Today's Weather - Monday, May 4, 2026
BOCA RATON, FL (Boca Post) (Copyright © 2026) — Breezy northeast winds will be a big part of the story today, along with periods of showers and thunderstorms—especially late morning into the afternoon. Some storms could bring heavy rainfall in a short time, so watch for ponding on roads and reduced visibility during downpours. Highs top out near 80 in Boca Raton, with gusts around 20–25 mph near the coast. Beach conditions are hazardous: Palm Beach County has a high rip current risk through this evening
South Florida is still dealing with a nearby front that has been lingering just to our south, and that setup is keeping showers and thunderstorms in the forecast through Tuesday. The National Weather Service notes an upper-level disturbance moving off the Florida Peninsula early this morning, which is helping air rise and supporting scattered storms over the Atlantic and along the east coast.
A weak area of low pressure is expected to form along the front near the northwestern Bahamas and then move away to the northeast as the day goes on. For Boca Raton, that matters because winds on the back side of that system turn and strengthen out of the northeast, pulling in some drier air from the north while still leaving enough moisture for storms to pop up.
Cloud cover is a key wildcard today. If skies stay mostly gray, storms may be more limited.
If we get a few breaks of sun, the extra heating can quickly boost storm coverage and intensity. Even with only modest instability, the forecast still highlights the potential for heavy rainfall in stronger cells.
Boaters and beachgoers should plan for rougher Atlantic conditions today. Northeasterly winds increase this morning, running about 15–20 knots with gusts up to 25 knots, and seas build to 5–7 feet (occasionally higher) offshore of Boca Raton.
Intracoastal waters will be choppy in exposed areas, and winds and seas can spike quickly near thunderstorms. Conditions improve tonight into Tuesday as winds ease and seas subside to 2–4 feet.
Along the coast, the onshore wind and swell are also driving a dangerous rip current setup, especially for Palm Beach County beaches. If you’re heading to the beach, swim near lifeguards and avoid entering the water if you’re not a strong swimmer.
