Marine Weather and Tide Forecast for Belleair Beach, FL

DISCUSSION
Issued at 300 AM EDT Tue Apr 21 2026

W/NW flow aloft overspreads the local area this morning between upstream C U.S. ridging and W Atlantic troughing. E/NE surface and low level flow continues locally between Srn U.S. ridging and a remnant frontal boundary over far S FL, with the associated gradient responsible for continued breezy to gusty conditions expected across WC/SWFL today into early Wednesday before gradually diminishing. Dry air advection into the peninsula behind the S FL frontal boundary coupled with elevated winds will lead to critical fire conditions locally today as a Red Flag Warning remains in effect from 11 AM to 8 PM for all of WC/SWFL. As such, outdoor burning is strongly discouraged as any fire that develops will pose a risk of rapidly spreading. Mostly clear skies likely otherwise with seasonably warm temps with highs in the low/mid 80s. Winds gradually diminish mid to late week while moisture gradually increases, lessening overall fire concerns, however rain chances remain rather limited offering little relief to ongoing drought conditions. PoPs increase slightly over the weekend mainly across the interior, with a slight chance of an afternoon or early evening shower or storm, otherwise the only other notable change will be a late week warming trend, with temps warming from the low/mid 80s mid week into the upper 80s to around 90s this weekend, and upper 80s/low 90s early next week.

FIRE WEATHER
Issued at 300 AM EDT Tue Apr 21 2026

Fire weather concerns remain elevated as conditions continue to be dry and windy, warranting a Red Flag Warning today from late morning through early evening.

However, minimum RHs reaching critical thresholds for a few hours remain likely on Wednesday afternoon for areas north of I-4 and west of I-75.
