Coastal Waters Forecast for Florida
National Weather Service Tampa Bay Ruskin FL
302 AM EDT Sat Oct 4 2025

Gulf coastal waters from Bonita Beach to the mouth of the
Suwannee River out to 60 NM.

Important notice to mariners...marine forecasts are issued at
least four times a day. Boaters on extended trips should
routinely monitor subsequent forecast issuances and updates for
the latest marine weather information.

The wave heights are forecast as significant wave height which is
the average of the highest one-third of the waves. The highest
waves may rarely be twice the significant wave height. The winds
and seas near thunderstorms may be higher than forecast.

Synopsis for the coastal waters from Bonita Beach to Suwannee River-
302 AM EDT Sat Oct 4 2025

.SYNOPSIS...

Dangerous conditions for small craft continue today as gusty winds
of 20 to 30 knots persist, driving peak offshore wave heights
anywhere from 5 to 8 feet high. Inland waters will also remain
choppy to rough, especially in areas with high wind exposure. There
is a 20% to 30% chance for mainly showers across coastal waters,
primarily in nearshore and inshore waters during the afternoon to
early evening hours. While winds are forecast to decrease somewhat
tomorrow, seas will still take longer to subside; and even though
the forecast calls for lighter winds next week, the winds are
forecast to remain elevated enough that seas of 2 to 4 feet will
likely persist.
