Today's Weather - Thursday, July 9, 2026
BOCA RATON, FL — Expect a mostly sunny, steamy Thursday with a high near 91 and heat index values up to about 106. A Heat Advisory is in effect, and the hottest part of the day will be late morning through late afternoon. Rain is unlikely today, so there won’t be much natural relief from the heat. Tonight stays mostly clear and warm, with lows around 83 and a steady southeast breeze
South Florida’s weather pattern today is set up to favor heat over storms. The National Weather Service notes a ridge of high pressure over Florida, with a steady southeast breeze coming in off the Atlantic.
That wind direction keeps the air moving, but it also helps feed low-level humidity into the area. At the same time, a dusty, drier layer of air moving in from the Sahara is sliding across the region today.
In plain terms, that “dusty air” tends to cap off cloud growth and makes it harder for afternoon thunderstorms to get going. That’s why Boca Raton’s forecast leans strongly sunny with little to no rainfall expected.
Even with that slightly drier layer overhead, the heat remains the main concern. The forecast calls for heat index values generally in the 105–110 range across South Florida, and Boca Raton is expected to top out near 106 this afternoon.
For the Boca Raton area beaches and nearshore waters (Jupiter Inlet to Deerfield Beach), southeast winds run about 5–10 knots today with seas around 2 feet. Tonight and Friday, winds increase to 10–15 knots, with seas 2–3 feet and a choppier Intracoastal at times.
Boaters should plan for locally higher winds and rougher conditions near any thunderstorms Friday into Saturday. Beachgoers should also keep an eye on building afternoon breezes and the heat on the sand; if storms develop later this week, get out of the water quickly when thunder is heard.
