Coastal Waters Forecast for Florida

National Weather Service Tampa Bay Ruskin FL

High pressure will generally remain over the waters for the next several days with benign conditions outside of showers and storms through the weekend and into next week with light winds and seas. The exception will be Monday and Monday night when a frontal boundary moves over the northern waters causing winds to be a bit elevated. Rain chances remain mostly low for the next several days.

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.
