Marine Weather and Tide Forecast for St. Petersburg, FL

DISCUSSION
Issued at 1201 AM EST Tue Jan 20 2026 High pressure over the southeast U.S. will move to the mid Atlantic coast today. This will cause boundary layer winds across the Florida peninsula to veer to the northeast off the Atlantic which will allow the cold airmass currently over the forecast area to moderate significantly over the next couple of days...with temperatures climbing to around climatic normals on Wednesday, and above climatic normals Thursday through Saturday.

A cold front is expected to push across west central and southwest Florida Sunday and Sunday night with a chance of showers, mainly north and central. Canadian high pressure will build over the forecast area in the wake of the front early next week with drier cooler air advecting across the region.
