Today's Weather - Sunday, June 14, 2026
BOCA RATON, FL — Mostly sunny and hot this morning, with a high near 90 this afternoon and heat index values pushing around 102. A few showers and thunderstorms are expected to pop up after about 2 p.m., with the best window for storms late afternoon into early evening. Any storm that forms can bring brief strong wind gusts and very heavy rain that quickly floods low spots. Tonight turns partly cloudy and warm, with a lingering storm chance early and a low near 78
South Florida’s familiar early-summer pattern stays in place today, and Boca Raton will feel it from the start: a quiet, bright morning followed by a stormier late day. The National Weather Service notes high pressure positioned over the Atlantic (with another weaker high over the eastern Gulf) is keeping the overall setup steady.
That means the sea breeze becomes the main trigger this afternoon, helping scattered thunderstorms develop from mid-afternoon into early evening. For Boca Raton specifically, rain chances are lower right on the coast than inland, but the metro can still get clipped—especially if storms drift east late in the day.
The bigger story is what happens if a storm moves over the same area for 20–40 minutes. The atmosphere is very humid, and the forecast discussion highlights deep moisture that supports high rainfall rates.
In plain terms: downpours can be intense enough to overwhelm storm drains, leading to quick street flooding in poor-drainage spots. A few storms could also briefly turn strong.
For Boca Raton’s coastal waters (Jupiter Inlet to Deerfield Beach), winds stay light this morning, generally south around 5–10 knots, with seas 2 feet or less. Tonight, south winds increase to about 10–15 knots with seas building to around 2 feet after midnight.
Monday brings a wind shift—west 5–10 knots early, then south 10–15 knots in the afternoon—still with low seas overall. The main marine hazard will be thunderstorms: brief squalls can create sudden gusty winds, choppy intracoastal conditions, lightning, and locally higher seas near storms.
If you’re boating, keep an eye on the sky after midday and have a quick plan to get to safe harbor.
