Coastal Waters Forecast for Florida
National Weather Service Tampa Bay Ruskin FL
301 AM EDT Sat Oct 11 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-
301 AM EDT Sat Oct 11 2025

.SYNOPSIS...

Hazardous marine conditions continue across coastal waters as gusty
winds of 20 to 25 knots build seas up to 8 feet offshore, making
conditions hazardous for small craft. Winds are forecast to begin
subsiding overnight, and seas will gradually subside in response.
However, this will take several hours, and slightly lighter but
still gusty winds on Sunday still favor conditions requiring small
craft to exercise caution on Sunday. As winds and seas become
lighter during the workweek, marine conditions will improve.
