Miami stepped out into a sticky start Thursday, with mostly clear skies and a muggy 76°F at Miami International Airport before sunrise. The sun is expected to hang around through the day, sending coastal highs into the upper 80s and inland neighborhoods into the low 90s. With humidity already running high, overnight lows will stay warm, offering little relief once the sun goes down.
Above average temperatures are projected to hold through the weekend, and forecasters are flagging a growing risk of heat related impacts across the metro area. Inland communities may reach the low to mid 90s while coastal spots top out in the upper 80s, and heat index values could climb into the upper 90s to around 100°F at times. Overnight lows are likely to remain in the upper 70s. This guidance comes from the National Weather Service.
This Week's Timeline
Mostly sunny, dry weather is expected through the weekend, with the most intense heat arriving Saturday and Sunday for many inland neighborhoods. Rain chances stay on the low side until early next week, when a frontal boundary could nudge showers and isolated thunderstorms into the area, mainly during Monday and Tuesday afternoons. If that front slows down or misses South Florida altogether, the heat will linger into midweek with only modest relief.
Afternoon Winds And The Coast
Daily sea breezes should keep oceanfront areas a few degrees cooler than the urban core, but those breezes will also kick up in the afternoons. South winds of roughly 5 to 13 mph are expected, with gusts up to around 18 mph possible over the weekend in some locations. Marine conditions are otherwise fairly tame, with typical onshore chop near 1 to 3 feet.
Heat Safety And Where To Cool Off
With heat index values flirting with the triple digits at times, it is a good idea to limit strenuous outdoor activity during peak afternoon hours, drink water often, and check on neighbors who may be more vulnerable to the heat. The City of Miami operates a network of cooling centers and park sites during the Extreme Heat Season, with locations and hours listed on the city website. If you do not have air conditioning, consider heading to a cooling center or calling 311 for assistance, and you can sign up for local heat alerts by texting ALERTMIAMI to 888777.
