Today's Weather - Monday, July 13, 2026
BOCA RATON, FL — Expect a hot, mostly sunny Monday with a hazy look to the sky and a high near 93. Heat index values may reach around 106, so plan outdoor time early and take frequent breaks in shade or A/C. Rain chances are low overall, but an isolated shower or thunderstorm could develop late this afternoon or early evening. Tonight stays mostly clear and warm, with lows near 81
South Florida stays under the influence of high pressure today, and that’s a big reason Boca Raton will run hot again. With that setup, winds are generally light early, then turn more southeast as the day gets going—enough to bring in a sea breeze, but not enough to guarantee widespread rain.
The other headline is the hazy air mass over the region. The National Weather Service notes Saharan dust is still in place, which can mute cloud growth and keep rain coverage lower than a typical July day.
Even with that drier air aloft, there’s still enough low-level moisture for a few storms to bubble up inland during the afternoon, then drift toward the metro areas near the coast around early evening. For Boca Raton specifically, the day-to-day impact is simple: lots of sun, very high heat, and only a small window for a brief storm.
The forecast calls for just a 20% chance of showers and thunderstorms today, with a high near 93. If a storm does form nearby, the drier mid-level air can sometimes help storms produce stronger wind gusts, so keep an eye out for quick-hitting downpours and sudden gusty winds late day.
For the Boca Raton and Deerfield Beach coastal waters, boating conditions stay fairly quiet today and tonight. Winds run generally south to southeast around 5 to 10 knots, with seas 2 feet or less and light chop on the Intracoastal.
While rain coverage is limited, an isolated late-day thunderstorm could still bring a brief burst of higher winds and lightning near the coast. Beachgoers should also remember that even on calmer surf days, rip currents can still occur—swim near a lifeguard and avoid going in alone, especially if storms approach.
