Treasure Coast Heats Up This Week, Temps Flirting With 90 by Thursday

TODAY: A comfortable, partly sunny Wednesday on the Treasure Coast with highs in the mid-80s. East winds at 5 to 10 mph keep conditions pleasant onshore. No rain expected — a rare clean slate heading into the workweek's close.

TONIGHT: Partly cloudy skies with lows dropping to the lower 70s. Southeast winds around 5 mph shift south after midnight, signaling the warmer air mass already building to the southwest, forecasters said.

THIS WEEK: Thursday is the headliner — highs surge into the lower 90s, the warmest readings of the week and a notable jump for early May. South winds at 5 to 10 mph gust near 20 mph late in the afternoon, particularly near and after sunset. That wind shift warrants attention for anyone with afternoon plans offshore. Thursday night brings mostly clear skies, lows in the mid-70s, and gusty southwest winds before calming after midnight. Friday settles back to around 90 degrees with a variable wind pattern — north early, pivoting east by late afternoon. No significant rain appears in the forecast, though the building heat and humidity are characteristic of late dry-season conditions on the Treasure Coast, typically the last few weeks before the June rainy season arrives and afternoon thunderstorms become daily.

ON THE WATER: Wednesday's east winds at 5 to 10 mph make for a smooth inshore morning — ideal for working the flats around the St. Lucie Inlet or running the Indian River Lagoon. Thursday's afternoon wind gusts up to 20 mph will build chop on nearshore Atlantic waters, so plan to return to the dock before 3 p.m. The morning fishing window both days looks significantly better than the afternoon. This light east-wind pattern resembles conditions from the same week last year, when snook activity picked up along Stuart's south seawall ahead of the first summer fronts.

ALERTS: No active National Weather Service watches, warnings, or advisories are in effect for Martin, St. Lucie, or Indian River Counties at this time.
