Gillby MCP

Florida marine conditions for AI agents. Tides, waves, wind, marine forecasts, hazards, red tide, rip currents, depth-aware boat routing and 84 verified coastal spots, through one remote MCP server and a public HTTP API.

Connect any MCP-compatible agent (Claude, ChatGPT, Cursor, Windsurf, Claude Code) to Gillby, a guide to Florida water. Public data needs no API key, no login, no signup: point your agent at https://www.gillby.com/mcp and ask.

Why Gillby exists

I'm newer to boating. I'm not from Florida, but I've been down here for years. My wife said it first: it was way too hard to get a good read on the weather without checking five different things, and when we asked an AI, it didn't have good answers on its own.

So I built Gillby. It's a hobby and a passion project: one map and one clock for a day on Florida water, plus this MCP server so your assistant can answer from real water data instead of guessing. More in Why I built Gillby.

"Can I run Boca Inlet tomorrow morning?" · "Is the Gulf Stream close off Palm Beach?" · "Any red tide on the Gulf coast?" · "Will my 2.5 ft draft make it to the sandbar at low tide?"

What makes it different

• One map, one clock. Wind, waves, tide, radar and lightning line up on the same timeline, per spot.
• Chop for your boat. Ride comfort accounts for boat size and hull, so a 21-foot center console gets a different answer than a big sportfish.
• Bridge clearance at today's tide. 97 bridges, with charted clearance adjusted for the NOAA tide prediction and the nearest live water-level gauge when it passes checks.
• Calibrated rain and thunder chances. Probabilities are recalibrated against airport observations, so a stated chance matches how often it actually rains.
• A 16-day outlook with honest confidence. Ensemble ranges and a trend against normal. From day 10 on, every day is labeled "Low confidence: trend only."
• Sources stay attached. Every answer carries source names, observation times, freshness and anything unavailable.

Tools

105 tools on the hosted server, generated from the live tool reference. Start with list_spots and get_conditions with view=summary; that one result carries the forecast, tides, scores, advisories, hazards, lightning and source freshness.

All 105 tools by category

Start here (8)

Tool	What it does
get_briefing	A short headline + <=60-word body written from the live data (numbers validated against the fact sheet; falls back to a template when no model is available). source says claude/openai/template. Rate limited: may call an LLM on a cold cache.
get_conditions	The full conditions bundle for a named spot: current waves (ft, s, deg FROM), wind (kt), tide (ft MLLW), water temp (F), activity scores with reasons, 7-day hourly forecast, hi/lo tides, best windows, NWS alerts, rip/red tide/bacteria hazards, lightning and an AI briefing. Kitesurf: kiteboarding contains rider-specific weather screening and unverified launch status; supply kiteStyle, kiteExperience, kiteMinWindKt and kiteMaxWindKt. No overall kite score or verified launch is implied. Activities: kite, surf, skim (flatland), skim-wave (wave riding), paddle (flatwater paddleboard), sup-surf (SUP surf). Skim scores are absent without shoreline observations; do not substitute other activity scores. Prefer view=summary unless you need every hour. boat= adds boat-specific chop comfort. For an arbitrary lat/lon use get_point_conditions. Start here for a current spot question with view=summary: this single result includes forecast, tides, scores, advisories, hazards, lightning and source status. Avoid duplicate hazard/tide calls unless a needed detail is absent. For beach questions, sea-model wave heights and NWS breaking-surf heights measure different things; their difference alone is not a forecast conflict. A swim no-go must not be followed by a recommendation to wade. Interpretation: omit boat unless the user supplied or confirmed it. Describe lightning as flashes observed or not detected in the stated window, never a clear/safe guarantee. Report unavailable/QC-failed sources even when freshness.stale=false; fresh does not mean every source is usable. Model sea height is not breaking surf height. Tide heights at different local MLLW gauges do not establish relative channel depths. High tide is not necessarily slack current. For kitesurfing use get_conditions with kiteStyle (freeride/waves/foil), kiteExperience and rider-supplied kiteMinWindKt/kiteMaxWindKt. Read kiteboarding for weather screening, gust spread and explicitly unverified launch status. Never infer the rider wind range, legal launch access or rescue coverage. Activity keys: kite, surf, skim (flatland), skim-wave (wave riding), paddle (flatwater paddleboard), sup-surf (SUP surf). Skim suitability is unscored without shoreline observations; missing scores must not inherit another activity. Offshore wind can favor surf while increasing paddleboard drift risk. A point depth cannot prove route clearance. Do not invent detection percentages, future readings, vessel ownership, or app settings instructions.
get_data_coverage	Published dataset inventory and verified spot coverage; distinguishes unavailable data.
get_health	Rolls up whether the ingest worker is running, which feed families (ndbc, coops, nws, openmeteo, goes19, coastwatch...) have stale sources, government dataset status and the GLM lightning feed. status is ok | degraded | down; HTTP 503 only when down. Check this before trusting 'no data' from other tools. detail=true lists every source.
get_release_updates	Read the current Gillby release version, date, supported MCP protocol and dated changes shared by the API and MCP. API URL versions are separate from product release versions.
get_source_status	Fresh, stale, unavailable and QC-rejected sources used by spot conditions.
get_spot	A single spot record plus now.scores (go/caution/nogo per activity for the current hour) when the worker has scored it.
list_spots	Every named Florida spot the app scores, with its lat/lon, kind, region and the NOAA stations used for it. Use the returned id with conditions, forecast, tides, hazards and briefing tools. include=status adds the current-hour go/caution/nogo band per activity. Use this for a map of verified coastal spots: the MCP app panel renders an interactive Florida map with selectable spots, nearby camera markers and conditions. Coordinates are geographic locations, not safe navigation routes.

Forecast and conditions (23)

Tool	What it does
compare_spots	Compare current conditions for up to five verified comma-separated spot IDs. Partial failures remain explicit.
get_activity_scores	Hourly published activity scores with reasons and vetoes. Missing activity scores are unscored.
get_air_temperature	Air temperature for a verified spot over the next hours. Includes timestamp, source status and explicit nulls when unavailable. Water temperature is F; atmospheric visibility is mi, not underwater visibility; current sign follows the assigned station convention.
get_chop	Boat ride and chop (use get_chop_history for past trends) for a verified spot over the next hours. Includes timestamp, source status and explicit nulls when unavailable. Water temperature is F; atmospheric visibility is mi, not underwater visibility; current sign follows the assigned station convention. For chop history or trends use get_chop_history with a verified spot ID. Preserve recorded versus reconstructed provenance, native 0–10 index and labels, coverage and gaps. Never invent assistant-defined rough/calm thresholds or silently substitute wave/wind series for native chop.
get_chop_history	Gillby's native 0-10 chop series: the latest 72 hours publicly, up to 31 days with a free Gillby account (OAuth sign-in); daily mean/max, coverage and 7-day trends. Recorded outputs and historical model reconstructions are identified separately. Never replace these with assistant-defined Calm/Moderate/Rough cutoffs or fabricate gaps. For chop history or trends use get_chop_history with a verified spot ID. Preserve recorded versus reconstructed provenance, native 0–10 index and labels, coverage and gaps. Never invent assistant-defined rough/calm thresholds or silently substitute wave/wind series for native chop.
get_cloud_cover	Cloud cover for a verified spot over the next hours. Includes timestamp, source status and explicit nulls when unavailable. Water temperature is F; atmospheric visibility is mi, not underwater visibility; current sign follows the assigned station convention.
get_currents	Predicted inlet currents for a verified spot over the next hours. Includes timestamp, source status and explicit nulls when unavailable. Water temperature is F; atmospheric visibility is mi, not underwater visibility; current sign follows the assigned station convention.
get_departure_windows	Published best windows filtered by activity. No windows means none were supplied, not a guarantee that every other hour is unsafe.
get_forecast	Hourly forecast for a spot (or lat+lon) starting at time (default now) for hours hours: waves, swell/wind-wave split, wind, gusts, tide, current, precip/thunder chance, and go/caution/nogo scores with reasons per activity. Also returns 7 daily score rows and best windows.
get_gulf_stream	Approximate Gulf Stream edge for a verified spot. Preserve source sample dates and unavailable states. Satellite clarity is a relative index, not measured dive visibility.
get_history	Read stored observations or forecast history for source and var. Forecast source uses forecast:model and requires spot. Public access covers the latest 72 hours; a free Gillby account (OAuth sign-in) allows windows up to 31 days; up to 1000 points. Latest revision/run wins. Rejected and suspect rows are excluded; unreviewed rows retain quality metadata. This is a stored source archive. source=forecast:* returns model estimates or predictions, even when valid times are in the past; it does not establish observed rainfall. For measured historical daily precipitation use get_rainfall_history and preserve coverage. For chop trends use get_chop_history with recorded/reconstructed provenance and gaps.
get_observations	Actual buoy and station observations for a spot with timestamps. These may differ from blended forecast conditions.
get_pressure	Air pressure for a verified spot over the next hours. Includes timestamp, source status and explicit nulls when unavailable. Water temperature is F; atmospheric visibility is mi, not underwater visibility; current sign follows the assigned station convention.
get_rain	Rain forecast probability and amount for a verified spot over the next hours. Includes timestamp, source status and explicit nulls when unavailable. Water temperature is F; atmospheric visibility is mi, not underwater visibility; current sign follows the assigned station convention.
get_rainfall_history	Observed daily precipitation from NOAA NCEI GHCN-Daily at one of six selected Florida airport stations, not archived forecasts. Required station, start and end (YYYY-MM-DD); completed dates only, 1900 onward, at most 366 inclusive days per request. Public, no API key. Returns daily values in inches, original flags, coverage, monthly summaries and totals. totalIn is null for incomplete coverage; partialTotalIn is only the sum of accepted reported values. Trace is not dry. Presumed-zero, incomplete-period and quality-flagged reports are excluded. Reporting dates are station climate days, not UTC hours. A station does not measure rainfall at a nearby beach, inlet or across a region. Recent records may lag or be revised. Use for how much precipitation fell: NOAA observed station records, not forecast archives. Preserve station, reporting dates, trace days, missing/excluded counts and coverage. Never present partialTotalIn as a complete monthly/yearly total. Station rainfall is not an area-wide measurement. Use get_rain for future amounts and get_history source=forecast:om_weather_best var=precip_in only for archived model estimates.
get_surf_forecast	NWS surf zone forecast for a verified spot. Preserve source sample dates and unavailable states. Satellite clarity is a relative index, not measured dive visibility.
get_thunder_forecast	Thunderstorm forecast for a verified spot over the next hours. Includes timestamp, source status and explicit nulls when unavailable. Water temperature is F; atmospheric visibility is mi, not underwater visibility; current sign follows the assigned station convention.
get_uv_forecast	UV forecast for a verified spot over the next hours. Includes timestamp, source status and explicit nulls when unavailable. Water temperature is F; atmospheric visibility is mi, not underwater visibility; current sign follows the assigned station convention.
get_visibility	Atmospheric visibility for a verified spot over the next hours. Includes timestamp, source status and explicit nulls when unavailable. Water temperature is F; atmospheric visibility is mi, not underwater visibility; current sign follows the assigned station convention.
get_water_temperature	Water temperature for a verified spot over the next hours. Includes timestamp, source status and explicit nulls when unavailable. Water temperature is F; atmospheric visibility is mi, not underwater visibility; current sign follows the assigned station convention.
get_wave_models	Published wave-model series and model spread for a spot; absent models stay unavailable.

get_wind	Wind and gusts for a verified spot over the next hours. Includes timestamp, source status and explicit nulls when unavailable. Water temperature is F; atmospheric visibility is mi, not underwater visibility; current sign follows the assigned station convention.

Tides, hazards and alerts (11)

Tool	What it does
get_derelict_vessels	Reported derelict vessels from the published agency dataset, with source and availability. Empty reports do not establish safe conditions.
get_hazards	Active NWS marine/coastal alerts (small craft, rip current, high surf, special marine, waterspout...) plus water hazards for a spot or lat+lon: rip current risk, red tide (FWC samples), bacteria (FDOH), sargassum, water clarity, king tide, Gulf Stream distance, lightning. Use before recommending swimming, diving or running an inlet. Interpretation: omit boat unless the user supplied or confirmed it. Describe lightning as flashes observed or not detected in the stated window, never a clear/safe guarantee. Report unavailable/QC-failed sources even when freshness.stale=false; fresh does not mean every source is usable. Model sea height is not breaking surf height. Tide heights at different local MLLW gauges do not establish relative channel depths. High tide is not necessarily slack current. For kitesurfing use get_conditions with kiteStyle (freeride/waves/foil), kiteExperience and rider-supplied kiteMinWindKt/kiteMaxWindKt. Read kiteboarding for weather screening, gust spread and explicitly unverified launch status. Never infer the rider wind range, legal launch access or rescue coverage. Activity keys: kite, surf, skim (flatland), skim-wave (wave riding), paddle (flatwater paddleboard), sup-surf (SUP surf). Skim suitability is unscored without shoreline observations; missing scores must not inherit another activity. Offshore wind can favor surf while increasing paddleboard drift risk. A point depth cannot prove route clearance. Do not invent detection percentages, future readings, vessel ownership, or app settings instructions.
get_hurricane_history	Search 26 completed seasons of NOAA NHC HURDAT2 best-track history (2000–2025), Atlantic and eastern/central Pacific. Includes tropical cyclones, not only hurricanes. Filter by basin, year range, name, storm ID, hurricane strength or recorded landfall. Paginated summaries by default; includeTrack=true returns UTC positions, sustained wind kt, pressure mb, status, special-event flags and 34/50/64 kt wind radii in nautical miles ordered NE, SE, SW, NW. Missing measurements are null. Landfall flags cover any coastline, not specifically the US. Finalized retrospective tracks are not forecasts; current 2026 advisories use get_hurricanes. Historical tracks alone do not measure local damage or future risk.
get_hurricanes	Active NHC tropical cyclones in the Atlantic and eastern/central Pacific. Returns position, maximum sustained wind (kt), pressure (mb), movement (degrees toward and kt), advisory timestamps and official advisory/forecast/cone links. Preserve stale/unavailable status. An empty active-storm list does not rule out developing systems or local hazards. The cone is not an impact boundary. Follow official local warnings.
get_king_tide	King tide forecast for a verified spot. Preserve source sample dates and unavailable states. Satellite clarity is a relative index, not measured dive visibility.
get_lightning	GOES-19 GLM lightning. With lat+lon: level (clear | watch 10-25 mi | danger < 10 mi in the last 5 min), nearest strike distance (mi) and time, strikes in 15 min, all-clear time (30 min after the last strike within 10 mi), SPC thunder outlook, and the last 30 min of flashes. Without lat/lon: status per spot. When the feed is stale, status is null and unavailableReason explains why (never a false 'clear'). Prefer list_spots for named spot coordinates. State no flashes detected in the observed window rather than no lightning exists. Stale/incomplete coverage means unknown. Do not supply detection rates that are absent from this result. Interpretation: omit boat unless the user supplied or confirmed it. Describe lightning as flashes observed or not detected in the stated window, never a clear/safe guarantee. Report unavailable/QC-failed sources even when freshness.stale=false; fresh does not mean every source is usable. Model sea height is not breaking surf height. Tide heights at different local MLLW gauges do not establish relative channel depths. High tide is not necessarily slack current. For kitesurfing use get_conditions with kiteStyle (freeride/waves/foil), kiteExperience and rider-supplied kiteMinWindKt/kiteMaxWindKt. Read kiteboarding for weather screening, gust spread and explicitly unverified launch status. Never infer the rider wind range, legal launch access or rescue coverage. Activity keys: kite, surf, skim (flatland), skim-wave (wave riding), paddle (flatwater paddleboard), sup-surf (SUP surf). Skim suitability is unscored without shoreline observations; missing scores must not inherit another activity. Offshore wind can favor surf while increasing paddleboard drift risk. A point depth cannot prove route clearance. Do not invent detection percentages, future readings, vessel ownership, or app settings instructions.
get_marine_alerts	Active and upcoming alerts for a spot, retaining start/end times and source links.
get_navigation_notices	USCG local notices to mariners from the published agency dataset, with source and availability. Empty reports do not establish safe conditions.
get_park_alerts	Coastal national park alerts and closures from the published agency dataset, with source and availability. Empty reports do not establish safe conditions.
get_rip_risk	Rip current risk for a verified spot. Preserve source sample dates and unavailable states. Satellite clarity is a relative index, not measured dive visibility.
get_tides	Predicted high and low tides (ft above MLLW, NOAA CO-OPS) for the next days days at a spot or lat+lon, the hourly tide height curve and inlet current (kt, + flood / - ebb), plus sunrise/sunset and moon phase. Times are ISO with the Eastern offset. Interpretation: omit boat unless the user supplied or confirmed it. Describe lightning as flashes observed or not detected in the stated window, never a clear/safe guarantee. Report unavailable/QC-failed sources even when freshness.stale=false; fresh does not mean every source is usable. Model sea height is not breaking surf height. Tide heights at different local MLLW gauges do not establish relative channel depths. High tide is not necessarily slack current. For kitesurfing use get_conditions with kiteStyle (freeride/waves/foil), kiteExperience and rider-supplied kiteMinWindKt/kiteMaxWindKt.

Activity keys: kite, surf, skim (flatland), skim-wave (wave riding), paddle (flatwater paddleboard), sup-surf (SUP surf). Skim suitability is unscored without shoreline observations; missing scores must not inherit another activity. Offshore wind can favor surf while increasing paddleboard drift risk. A point depth cannot prove route clearance. Do not invent detection percentages, future readings, vessel ownership, or app settings instructions.

Routes, depth and boats (7)

get_boat	A single boat record from the library.
get_depth	Actual NOAA ENC chart depth and optional DEM depth at a Florida coordinate, with charted hazards, channel context and restriction zones. A point check does not prove clearance along a route. Interpretation: omit boat unless the user supplied or confirmed it. Describe lightning as flashes observed or not detected in the stated window, never a clear/safe guarantee. Report unavailable/QC-failed sources even when freshness.stale=false; fresh does not mean every source is usable. Model sea height is not breaking surf height.

plan_route	Requires a free Gillby account (OAuth sign-in). Chart-aware water routing between from/to spot IDs or lat,lon. Supply a confirmed library boat ID or measured draft, with beam, airDraft, ukc, bridgeMargin and speed overrides in feet/knots. Checks chart depths and tides along the geometry, samples across supplied beam, identifies bridges and restrictions, checks predicted MHW bridge clearance when data permits, and adds route weather samples. Does not infer saved vessel settings. Supports ordered via stops and a hard corridor=icw constraint. Cold charts may take 110 seconds. Interpretation: omit boat unless the user supplied or confirmed it. Describe lightning as flashes observed or not detected in the stated window, never a clear/safe guarantee. Report unavailable/QC-failed sources even when freshness.stale=false; fresh does not mean every source is usable. Model sea height is not breaking surf height.

Includes official Boca Raton/Fort Lauderdale lifeguard-report links. Community records are not live beach warnings; no sightings does not establish absence. Man-of-war are siphonophores. Use bbox to narrow the sample; limit defaults to 20 (maximum 100). Shark, jellyfish and man-of-war records are dated published observations, not live tracking, beach warnings, abundance estimates or swimming-safety scores. Preserve observation dates, uncertainty, attribution and source availability. No records does not mean the animals are absent. Source checked time is not observation time. Man-of-war are siphonophores, not true jellyfish. Local lifeguard links are not ingested current warnings; check the source report date. Never apply NOAA's Chesapeake sea-nettle forecast to Florida.

Shark, jellyfish and man-of-war records are dated published observations, not live tracking, beach warnings, abundance estimates or swimming-safety scores. Preserve observation dates, uncertainty, attribution and source availability. No records does not mean the animals are absent. Source checked time is not observation time. Man-of-war are siphonophores, not true jellyfish. Local lifeguard links are not ingested current warnings; check the source report date. Never apply NOAA's Chesapeake sea-nettle forecast to Florida.
get_temperature_fronts	Satellite sea temperature fronts from the published agency dataset, with source and availability. Empty reports do not establish safe conditions.
get_usgs_water	USGS flow, local gauge height, salinity and water temperature from the published agency dataset, with source and availability. Empty reports do not establish safe conditions.
get_water_clarity	Satellite water clarity for a verified spot. Preserve source sample dates and unavailable states. Satellite clarity is a relative index, not measured dive visibility.

Datasets (2)

Tool	What it does
get_dataset	The latest payload of one dataset from list_datasets, including sharks and jellyfish. These marine-life records are dated observations, not live beach warnings; no records does not imply absence. bbox filters list datasets; category filters USCG notices (e.g. bridge,hazard); homeZone=true limits discharges to the home zone; geometry=true includes MPA polygons. 503 when the dataset has never loaded.

get_my_notification_settings	Read notification preferences and actual delivery availability. Requires your Gillby account and explicit account consent.
get_my_place	Read one saved place. Requires your Gillby account and explicit account consent.
get_my_settings	Read saved vessel, preferences and notification settings. Missing vessel measurements remain null. Requires your Gillby account and explicit account consent.
get_my_trip	Read one saved trip. Requires your Gillby account and explicit account consent.
get_my_vessel	Requires OAuth login to your Gillby account. Reads only your saved vessel and route clearance settings. No writes and no other account access.
list_my_places	Read your saved places and favorites. Requires your Gillby account and explicit account consent.
list_my_trips	Read your saved trips. Requires your Gillby account and explicit account consent.
plan_my_route	Requires OAuth login. Uses your saved vessel, draft, air draft, speed, under-keel and bridge margins for actual chart routing. Explicit measurements override saved values. Never guesses missing required measurements.
save_my_place	Save a place or favorite. Supply a unique requestId and reuse it when retrying the same save; reused IDs with different input are rejected. Requires your Gillby account and explicit account consent.
save_my_trip	Save a trip. Supply a unique requestId and reuse it on retry. Saving does not assess navigation safety. Requires your Gillby account and explicit account consent.
update_my_notification_settings	Save notification preferences. Hosted delivery is in-app only; this does not enable push, email or notifications on this AI client. Requires your Gillby account and explicit account consent.
update_my_place	Update specified saved-place fields. Requires your Gillby account and explicit account consent.
update_my_settings	Update only specified vessel or preference fields. Requires your Gillby account and explicit account consent.
update_my_trip	Update specified trip fields; this does not recheck route safety. Requires your Gillby account and explicit account consent.

Other (3)

Tool	What it does
get_fishing_heatmap	Published Florida mahi, blue/white marlin, tarpon and snook evidence: dated NOAA commercial catches and research/community occurrences, source/license credits, coordinate uncertainty, seasonal record counts and configurable 0.25/0.10/0.05/0.02/0.01/0.005-degree heatmap cells. Historical records are not live fish locations, migration tracks, abundance, catch rates or catch probabilities. Sampling/fishing effort is uncorrected; absent records do not establish fish absence. from/to are inclusive YYYY-MM-DD observation dates; month pools all selected years. Source check time is not observation time. Recency weighting defaults to recent: exponential 365-day half-life based on observation dates, not source retrieval. weighting=historical gives equal weights. No upstream downloads on tool calls. Preserve species, observation dates, source credits, coordinate uncertainty, query coverage, partial/stale flags and fishing-effort bias. Heatmap color is record density, never fish abundance or catch odds. Commercial catches and occurrences must remain distinguishable. No generated migration paths.

Hurricanes and historical tracks

Use get_hurricanes for active NHC cyclones and get_hurricane_history for 2000–2025 HURDAT2 history: 973 cyclones and 27,812 track records in the Atlantic and eastern/central Pacific. Set includeTrack=true to retrieve a storm's recorded track from its first observation to its last, with UTC positions, wind, pressure and landfall flags. Filter by basin, season, name or exact storm ID; paginate summaries before requesting many full tracks. No public-data login or API key.

{"name":"get_hurricane_history","arguments":{"query":{"id":"al122005","includeTrack":true}}}

Read the complete hurricane API/MCP guide, app and live input schemas. Finalized history ends in 2025; ongoing-season advisories use the active tool. Tracks are retrospective observations, not forecasts or damage estimates.

HTTP API

Everything is also available over ordinary HTTP GET. Public endpoints need no key; account endpoints, route planning and history older than 72 hours need OAuth with a free Gillby account.

curl --fail-with-body 'https://www.gillby.com/api/v1/conditions?spot=boca-inlet&view=summary'

• Developer guide, examples, error codes and versioning: https://www.gillby.com/developers
• OpenAPI schema: https://www.gillby.com/api/v1/openapi.json
• AI-readable docs: llms.txt and llms-full.txt

Rate limits. About 60 data requests per minute per client, shared between the API and MCP. Over the limit you get HTTP 429 with Retry-After; honor it and back off. A request without a spot returns 400 spot_required.

Data and credits

Data comes from NOAA and NWS (forecasts, marine zones, alerts), NDBC buoys, NOAA CO-OPS tides and water levels, NOAA GOES-19 lightning, Open-Meteo and ECMWF/GFS models, NOAA CoastWatch, USGS, FWC, FDEP, FDOH, USCG and other public sources. Each response names the sources it used.
