Coastal Waters Forecast for Florida
National Weather Service Tampa Bay Ruskin FL
431 AM EDT Sun Oct 12 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-
431 AM EDT Sun Oct 12 2025

.SYNOPSIS...

As winds subside, wave heights will also decrease today. However,
small craft should continue to exercise caution through the morning
as it will take several hours for seas to subside, even as the winds
decrease. Quieter marine weather is expected for the next several
days as a northerly and eventually more northeasterly flow prevails
through the week. With the northeast flow especially, there will be
periods of gustier winds from near sunset through about midnight
each night. This favors seas increasing by about a foot or so
through the overnight hours before gradually decreasing towards
morning.
