Miami woke up to clear skies and a warm start on Saturday, July 11, 2026, with Miami International Airport already sitting near 75°F at 5:30 a.m. EDT. That relatively comfortable morning air will give way to another hot, sticky afternoon, with highs expected near 91°F and humidity pushing feels-like temperatures into the triple digits. If you have outdoor plans, you will want to front-load them into the early morning or save them for the evening, with plenty of water and shade within arm’s reach.
Heat Advisory And What To Expect
A Heat Advisory is posted for metro Miami from 11 a.m. to 7 p.m. Saturday, and forecasters say heat-index values could climb to around 105–110°F during peak afternoon hours. The actual high should land near 91°F, with only a slight chance of brief, late-day showers or thunderstorms, mainly over inland areas. According to NWS Miami, anyone who has to be outside during the advisory window should take added precautions to avoid overheating.
Where To Find Relief
Miami-Dade and the City of Miami are keeping a network of cooling sites up and running, including libraries, parks, and community centers, and outreach teams are working to connect people experiencing homelessness with relief options. Hydration stations and temporary cooling areas are also set to pop up at some large event venues and fan-fest locations. For a full rundown of cooling-site locations and operating hours, check Miami-Dade County.
Storm Chances, Winds And The Week Ahead
Storm chances stay on the low side, with about a 20% chance of showers and thunderstorms developing after roughly 2 p.m., primarily inland. Any storms that do bubble up should be short-lived but could bring some gusty winds. East-southeast breezes are expected to run about 7–10 mph, and marine conditions should stay under roughly 3 feet outside of isolated convective squalls. The local forecast discussion also flags another plume of Saharan dust sliding into the region this weekend, which is expected to dry out the air a bit and keep rain chances limited while stretching out this hot pattern, according to NWS Miami.
Quick Safety Tips
Drink plenty of fluids, spend time in air-conditioned spaces when you can, and avoid prolonged or strenuous outdoor work from late morning through the early evening. Check in on older neighbors, young children, and pets, and keep an eye out for signs of heat illness such as heavy sweating, weakness, dizziness, or confusion, seeking medical help if symptoms worsen. If you are headed to an outdoor event, build in water and shade breaks and stay alert for sudden lightning with any afternoon storms.
