Miami is waking up warm, cloudy and sticky this Monday, May 4, 2026, with mid 70s on the thermometer and dew points lurking in the low 70s. Showers and scattered thunderstorms are in play through Tuesday, with the best shot for rain and rumbles this afternoon and early evening and highs near 80°F. A breezy north to northeast wind, gusting around 20 mph, will kick up choppy seas and a heightened rip current threat along the coast.
Afternoon Storm Timing
Rain chances build through the morning, with the prime window for showers and thunderstorms from late morning into the early afternoon on Monday, May 4, 2026. Any storms that pop could deliver brief heavy downpours and gusty winds. Expect north winds around 9 to 15 mph, with gusts near 20 mph, and localized rainfall of about a quarter to a half inch in the stronger cells. That forecast comes from the National Weather Service office in Miami, according to NWS Miami.
Beaches and Boating
Onshore winds and a returning northeasterly swell will keep the Atlantic looking rough. Palm Beach beaches are under a High Rip Current Risk, while Broward and Miami-Dade coastlines sit at a moderate risk. The northern Atlantic waters are under a Small Craft Advisory for Monday, May 4, 2026, with seas of 4 to 6 feet offshore. Boaters should stick to protected harbors, and swimmers should pay close attention to lifeguard flags. For a refresher on safety basics and what those flag colors mean, revisit when rip currents crashed a Miami Beach weekend.
Midweek Heat
By midweek, the pattern flips from soggy to steamy. Drier, hotter air will settle over South Florida, with inland highs expected in the low to mid 90s from Wednesday, May 6, through Friday, May 8, 2026. Coastal spots look a bit less intense in the upper 80s, but it will still feel hot. Apparent temperatures could push into the upper 90s to around 100°F, raising the risk of heat-related problems for outdoor workers and vulnerable residents. The National Weather Service is flagging an elevated heat risk for the middle to end of the week, according to NWS Miami.
Quick Tips
At the beach, swim only near lifeguards, and if a rip current grabs you, stay calm, float, and swim parallel to the shore until you can angle back in. If you are not an experienced mariner, skip the small boats while seas are up.
Later this week, when the heat cranks up, drink plenty of water, avoid heavy outdoor activity in the middle of the day, and check on older neighbors, children and pets who might struggle with the hotter conditions.
