Miami woke up steamy on Wednesday, with clear skies, sticky air and that familiar South Florida wall of humidity. Temperatures hovered near 75F at Miami International Airport, humidity sat around 89 percent, and a light southeast breeze near 12 mph kept visibility close to 10 miles while the Atlantic stayed warm. Sunshine should hold through the day, but inland neighborhoods are set to heat up even more as the week rolls on.
Today And The Week Ahead
Expect mostly sunny skies today with a high near 84F and a warm overnight low around 79F. Thursday turns up the dial a bit, with highs near 87F, and inland spots are poised to push into the low to mid 90s by late week. Most afternoons will feature an east-southeast sea breeze that keeps the coast a few degrees cooler than neighborhoods farther inland, so beachside will feel slightly less brutal than the suburbs.
Heat Risk Rises This Weekend
The warming trend sticks around into the weekend and early next week, raising the odds of heat-related impacts across the metro. The National Weather Service is highlighting probabilities of a Major HeatRisk of roughly 50 to 70 percent on Friday and 70 to 80 percent for Saturday through Monday, with heat indices climbing into the upper 90s to around 100F in spots. That means outdoor workers, athletes and anyone planning long stretches outside should plan on extra breaks and plenty of water, according to NWS Miami.
Beaches, Boats And Afternoon Breezes
There is a moderate rip-current risk along southeast Florida beaches this week, so swimmers should pay attention to the flags and lifeguard instructions instead of just the selfie lighting. Offshore, expect east-southeast winds with seas around 12 feet and afternoon sea breezes that can change local conditions quickly. Boaters and beachgoers should check in with local lifeguard updates before heading out.
How To Stay Cool
City resources are on standby during heat events, as the City of Miami maintains a network of cooling centers and community sites where residents can escape the worst of the heat. Stay hydrated, avoid strenuous activity during the hottest hours of the afternoon, check on older neighbors and never leave children or pets in parked cars. For locations, see the City of Miami.
Bottom line: it is a sunny, muggy start to Wednesday, and the heat will build into the weekend, so plan outdoor activities for the morning or evening and keep that water bottle close.
