Synopsis for the coastal waters from Bonita Beach to Suwannee River
923 AM EST Wed Feb 11 2026

SYNOPSIS

Rather quiet marine conditions will continue through the week with the only concern being the potential for sea fog development, especially off the Nature Coast north of Tampa Bay. Otherwise, southerly winds begin to increase Sunday as a cold front moves toward the waters, likely reaching advisory criteria Sunday afternoon into Sunday night. Showers and a few thunderstorms will be possible ahead of this boundary Sunday into Sunday night, then winds veer to northerly behind the front and diminish Monday with pleasant marine conditions returning early next week.
