Coastal Waters Forecast for Florida

National Weather Service Tampa Bay Ruskin FL

High pressure will hold over the waters through the period with relatively light winds and seas. The main hazard will be scattered showers and thunderstorms which may produce locally gusty winds and rough seas, mainly during the overnight and early morning hours.

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.
