Today's Weather - Sunday, May 10, 2026
BOCA RATON, FL (Boca Post) (Copyright © 2026) — Partly sunny skies will carry Boca Raton through the morning and early afternoon, but it will feel noticeably hotter than the thermometer thanks to high humidity. Highs reach the upper 80s, with heat index values pushing near 100 during the peak of the afternoon. A brief shower or thunderstorm can’t be ruled out late today, with the better odds closer to late afternoon and early evening. Tonight stays warm and muggy with increasing clouds and only a small chance of a late-evening shower or storm
South Florida stays under a broad “lid” of warm air aloft today and Monday, which helps keep the first half of the day fairly quiet but also allows heat and humidity to build quickly. The National Weather Service notes high pressure at the surface remains in control, while southerly winds continue feeding moist air into the region.
In plain terms: it’s a classic steamy May setup, and it won’t take much sunshine for conditions to turn uncomfortable. For Boca Raton, the forecast calls for a high near 88 today with heat index values as high as 100.
The Weather Service is highlighting a high chance of heat-related impacts across South Florida through Monday, even though no formal heat advisories are posted. If you’re outdoors this afternoon, plan extra water and breaks, and try to schedule strenuous work or exercise earlier in the day.
Storm chances are still on the lower side today, but they’re trending upward. With plenty of low-level moisture in place, scattered thunderstorms may pop up late in the day, especially from mid-afternoon into early evening.
Boaters and beachgoers along the Boca Raton coast can expect generally manageable marine conditions today into early week, with light to moderate southerly winds. The local Atlantic waters nearshore run around 2 feet today, with intracoastal waters at a light chop.
Winds increase a bit tonight (around 10 to 15 knots), then remain mostly around 10 knots Monday. Keep an eye on the sky each afternoon: scattered thunderstorms can create sudden, locally hazardous gusts and choppy seas.
By midweek, seas may build notably offshore (the marine forecast shows higher seas Wednesday), which could mean rougher conditions for small craft and a more challenging surf zone.
