Head out or stay home — the answer before you leave the house

For jet skis and small boats: pick your area and your point — a public ramp, a pass, a waterfront — and get one plain-language verdict — GO, BORDERLINE or NO-GO — computed live from the official marine forecast, the nearest real buoy, the tide, and satellite water clarity. The ride home counts as much as the ride out.

Today at your point — live

Pick an area, then a point in it — a public boat ramp, a pass, a waterfront. The verdict below is computed right now, in your browser, from the current NWS marine forecast for that point's waters, cross-checked against the nearest buoy and tide station to the point. Your pick is remembered on this device.

The index: Florida's official artificial-reef list (FWC — every published site, with its material, depth and year) plus the public ramps, passes and waterfronts in the areas below. Tap a result and the full panel — forecast, nearest buoy, tides, water temperature, satellite clarity — opens for that exact point.

The days ahead at your point

The same verdict, day by day, from the official NWS zone forecast for your point's waters — for as many days as the forecast runs: usually about five, a full week when the source publishes one. Each day pairs its daytime and night periods and is judged by the worst of them, with the same thresholds as today's card. Pick a different point above and this strip follows it.

Areas and their points — live

Coverage areas anchored to public places — towns, passes, public boat ramps and waterfronts. Each area holds a few public points; tap a point and its card runs the full live check: the NWS forecast for the point's own waters, the nearest buoy and tide station picked by distance, and the thresholds below. The weather is whatever NWS and NOAA say right now.

Not in Florida? Pick your own waters

The same official data covers every US coast. Choose your marine zone below — zones are named the way a person would say them: the stretch of coast and how far out the water runs. If yours isn't listed, type its code (you'll find it on any NWS marine forecast page).

…

The map behind the codes — in plain words

Forecasts and buoy reports come with codes like GMZ853 or 42013. Nobody memorizes those. On this page every station is named in words first, with the code in parentheses for anyone who wants to check the source — and every point and every picked zone gets its nearest stations chosen by distance, automatically.

The zones behind the areas

  • Englewood to Tarpon Springs, out to 20 nautical miles (zone GMZ853) — the home-coast zone: it decides the Anclote & Tarpon Springs, Clearwater, Dunedin and St. Petersburg areas.
  • Biscayne Bay (zone AMZ630) decides Miami; the Straits of Florida off the Keys (zone GMZ075) decides Key West; Galveston Bay (zone GMZ335) decides Galveston. Every area on this page is labeled with the zone that actually forecasts its waters.

Each point sits in exactly one marine zone, and the verdict reads that zone's official forecast. A zone forecast is an average over a big stretch of water — your point can sit in the rough part of it, which is why the buoy cross-check below matters.

Buoys and tide stations — picked by distance

  • For the home coast the pick usually lands on the shelf buoy west of the Tampa Bay entrance, in about 80 ft (25 m) of water (station 42013) — what the wind and waves are actually doing offshore right now, not what was forecast.
  • Pick any other area or zone and the page measures from that point to every major buoy and tide station in its built-in tables, then reads the closest ones — and says how far away they are. If the nearest station is more than 150 nautical miles off, the card says so honestly and the verdict runs on the forecast alone.

Small Craft Advisory means the weather service is officially warning small boats: winds around 20 knots or more, or seas of 7 ft and up, expected. On this page an active advisory for your waters is an automatic NO-GO — no threshold math overrides it.

Water clarity from satellites — last 3 days

True-color satellite photos of the water around your selected point, one per day. Read them at the point (yellow dot): a green, milky band along the shore is churned-up water — poor visibility offshore. Dark blue is clear water. Frames load live from NASA; if today's pass isn't published yet, the strip honestly shows the latest frame that exists and labels it with its real date.

Three satellite frames of the Anclote coast, Oct 23–24

The storm check, Oct 23–24, on the home coast: Friday morning (left) the murk is a thin green strip along the islands and the water offshore is dark blue. By Saturday morning (center, and again in the afternoon pass, right) the green band has widened and pushed seaward — Tarpon Springs and Dunedin sit inside it. Water clarity offshore was already falling a day before the wind peaked. No frame for Sunday the 25th existed yet at check time — the morning Terra pass comes around 10:30 AM. The strip above always shows the three most recent days for your point.

The rules behind the decision

No magic: a verdict is a check against a few hard thresholds. They weren't written by a marketer — they were written by a man an east wind nearly left in the Gulf once. The live cards above run exactly these rules.

≤ 10 kt

Offshore wind (off the land)

East, northeast, southeast: ≤10 knots, gusts ≤14 as the base limit. The farther out your point, the stricter it gets: beyond 6 miles offshore — ≤8 / gusts 12; only inside 3 miles is ≤12 / gusts 16 allowed. Every knot of offshore wind is a headwind on the way home.

≤ 12 kt

The ride home

A following sea on the return leg: ≤12 knots, gusts ≤16. The verdict is computed for the trip home, not the trip out: riding out downwind is always easy — the question is what it looks like three hours later.

≤ 2 ft

Wave height and period

Height ≤2 ft (0.6 m). If the period is ≤4 s, only ≤1.5 ft (0.45 m): short chop hits more often and swamps you worse than a taller, longer swell.

2 days

The visibility wait

After wind over 15 knots, the water turns murky. Wait two calm days for the sediment to settle — and check the satellite strip above: green at your point means the wait isn't over.

1–2 PM

Storms — a hard deadline

If scattered thunderstorms are in the afternoon forecast, the verdict carries a deadline: be back by 1:00–2:00 PM — not a suggestion, but the time the whole trip is built around.

NWS

Marine forecast only — and advisories rule

The source is the NWS marine zone forecast and NDBC buoys — not land weather and not a “model average.” An active Small Craft Advisory for your waters is an automatic NO-GO.

The east-wind trap

Off the Anclote coast, the open water lies to the west of every ramp. An east wind pushes you out on a following sea — fast and fun. The way back is straight into wind and waves, on a tired rider, sometimes under a building storm front. That's why every verdict here weighs the ride home on its own — and downgrades because of it, even when the ride out looks perfect.
