BOCA RATON, FL (Boca Post) (Copyright © 2026) — Wednesday, May 20, 2026 BOCA RATON, FL (Boca Post) (Copyright © 2026) — Sunshine dominates today with a high near 85 and an east wind around 10–13 mph, gusting near 18 mph. The big headline is the beach: a high risk of rip currents continues along the Atlantic coast through this evening. It will stay warm tonight (near 79) with a light-to-moderate onshore breeze. Rain chances remain low overall, with only a small chance of a brief shower or storm late Thursday into the weekend
Boca Raton’s weather pattern is staying locked in place, and it’s a classic late-spring setup for South Florida: steady Atlantic high pressure at the surface keeps an onshore (east) breeze going, while a broad ridge of warmer air aloft sits over the region. That combination favors lots of sun for the east coast metros, including Boca Raton, and it also helps keep the ocean pushing toward the beach.
The National Weather Service notes a pocket of drier air a few thousand feet up is sliding in from the Atlantic side. In plain terms, that “dry layer” makes it harder for storms to grow tall and last long, even though there’s still enough low-level moisture for clouds to bubble up during the afternoon.
So while showers and thunderstorms will still be possible each day, the best focus for more active weather remains inland and toward southwest Florida where sea-breeze boundaries collide. For Boca Raton, that translates to mostly dry conditions with only a low-end chance of a quick, hit-or-miss shower or storm—mainly late day Thursday and again at times Friday through early next week.
If a storm does pop, the main concerns are lightning, a brief burst of gusty wind, and a quick downpour. Heat is the other story.
For the Boca Raton area waters (Jupiter Inlet to Deerfield Beach), expect east winds around 10–15 knots today and tonight with seas 2–3 feet. Boating conditions are generally manageable, but the intracoastal will run a moderate chop, especially in open stretches.
Winds stay up into late week, turning more southeast and increasing Friday into the weekend (15–20 knots) with seas building to 3–5 feet and occasionally higher offshore. Any thunderstorm can briefly kick up stronger gusts and rougher seas.
Along the beach, the onshore flow supports a high rip current risk through this evening—swim near lifeguards and avoid unguarded areas.
