Treasure Coast Heats Up Through the Weekend, Saturday Gusts to 25 MPH

TODAY: Partly cloudy skies Thursday with highs climbing into the upper 80s. West winds of 5 to 10 mph will shift south at 10 to 15 mph by late afternoon, according to the National Weather Service. No rain is in the forecast.

TONIGHT: Partly cloudy and comfortable. Lows dip into the upper 60s — one of the last genuinely cool nights before summer's grip tightens. Southwest winds of 5 to 10 mph turn westerly after midnight.

THIS WEEK: The heat builds. Friday brings mostly sunny skies with another upper-80s high and a wind shift back to the southeast by evening — a pattern that tells fishermen the sea breeze is reasserting itself ahead of the weekend. Friday night lows hold in the lower 70s. By Saturday, temperatures push into the lower 90s, making this the warmest stretch of the spring so far on the Treasure Coast, forecasters said. That's roughly five to seven degrees above the late-April historical average for the region — a notable early-season heat surge.

ON THE WATER: Thursday afternoon's south-to-southwest flow at 10 to 15 mph will build a light chop on the nearshore Atlantic, keeping conditions manageable for smaller vessels. Saturday is the day to watch: southwest winds at 10 to 15 mph with gusts up to 25 mph will roughen the inshore waters and push seas on the open Atlantic into the two- to four-foot range. Morning hours Saturday offer the best fishing window before the wind builds — the jetties at Fort Pierce Inlet and the flats off Sewall's Point typically calm down faster than open-water spots. Boaters planning a Saturday run offshore should check the latest marine forecast and file a float plan.

ALERTS: No active National Weather Service watches, warnings or advisories are in effect for Martin, St. Lucie or Indian River counties as of Thursday morning.
