Miami woke up mostly cloudy and around 79°F at Miami International Airport this morning, and the heat is only climbing from there. Saturday, May 2, 2026, is on track to be a scorcher, with afternoon highs pushing into the lower 90s and heat index values flirting with 100°F. Gusty southerly winds are expected to kick up later today, and officials are already flagging increased marine and fire risks for parts of South Florida. Anyone with outdoor plans should build in extra water breaks and absolutely avoid leaving children or pets in parked cars, even for a short time.
Afternoon Heat And Hazards
Across the metro, temperatures are forecast to reach the low 90s, with Miami International expected to top out near 93°F. The heat index is projected to climb into the upper 90s to around 100°F, which means prolonged time outside could lead to heat-related illness for people who are not careful. The National Weather Service in Miami has issued a special weather statement that calls out the dangerous heat and the potential for heat stress, and forecasters are also highlighting afternoon wind gusts that will worsen marine and fire weather conditions.
A Red Flag Warning is posted from 11 a.m. to 7 p.m. for some inland areas where dry fuels and gusty winds could make fires spread quickly. Offshore, Small Craft Advisories are up for the northern Atlantic waters today as building seas and stronger winds create rough conditions. Boaters, anglers and anyone planning time on the water should keep up with the latest forecast discussion and current advisories from the National Weather Service in Miami.
Local Resources And Safety
For residents without reliable air conditioning, Miami-Dade County maintains a network of cooling sites and library locations during the hot season. You can call 2-1-1 or check local listings to find the closest option and the hours of operation. Health officials recommend keeping outdoor activities short, wearing light and loose-fitting clothing, drinking water frequently rather than waiting to feel thirsty, and checking in on elderly or medically vulnerable neighbors.
At the coast, lifeguards are warning about elevated rip currents along the Palm Beaches and a moderate rip current risk along Broward and Miami-Dade beaches. Swimmers are urged to stay near staffed lifeguard towers and to avoid going into the water alone, especially if they are not strong swimmers. Details on county cooling locations and hours can be found through the Miami-Dade County cooling sites information page.
Sunday Storms And Timing
A frontal boundary is expected to slip south overnight into Sunday, May 3, and it will bring a big jump in rain and storm chances. Forecasters have rain probabilities near 90 percent on Sunday, with the setup supporting showers and thunderstorms capable of locally heavy downpours. Most neighborhoods should only see modest rainfall totals, but mesoscale guidance points to isolated pockets of 1 to 3 inches where storms repeatedly track over the same east coast metro areas, which could trigger brief urban flooding on poor-drainage streets.
Behind the front, temperatures are projected to ease back into the low 80s on Monday, offering a bit of relief after the weekend heat. Residents are encouraged to monitor updated forecasts and any new alerts from the National Weather Service in Miami as the exact timing of the front and storms becomes clearer.
