Marine Weather and Tide Forecast for Palm Harbor, FL

DISCUSSION
Issued at 250 AM EDT Wed Mar 18 2026

The upper level trough will continue to move slowly east across the eastern U.S. and eventually out into the western Atlantic Ocean late in the week. A couple of shortwaves moving through this trough will move over the region tonight and again Thursday night bringing just some mid and high clouds.

Meanwhile at the surface, high pressure moving across the eastern U.S. will continue to build into the area through the work week and eventually settle over the region this weekend into early next week. The somewhat breezy northeast to north low level flow will persist across the area into Thursday, then diminish Friday and become rather light over the weekend into early next week with an afternoon sea breeze developing each day.

We'll see a gradual moderating trend through the weekend into early next week and with a rather dry airmass holding across the area the next slim chance of rain is not until next Tuesday.
Daytime high temperatures will get back to near normal by Friday and then a few degrees above normal this weekend into early next week. Overnight lows however will take until Sunday, if not Monday, to climb back to near normal, thanks to the rather dry airmass across the region.

A dry air mass will remain over the region with relative humidity values dipping to critical levels from around the Tampa Bay area north across the Nature Coast this afternoon, and across Levy and Citrus counties Thursday afternoon. However, no Red Flag issues are expected as sustained 20 foot winds remain less than 15 mph and the Significant Fire Potential is low. The rather dry airmass will remain across the area through the weekend with temperatures gradually moderating back to near to a few degrees above normal.
