Miami woke up Friday, July 10, 2026, already sweating. Skies were mostly clear, humidity was cranked up, and temperatures sat in the mid-80s before many people even grabbed their first coffee. By afternoon, the actual high will hover near 90°F, but it will feel far hotter, with the heat index expected to spike into the 105–110°F range. A southeast breeze may kick up at times, and scattered showers or thunderstorms later in the day could bring brief, very localized relief.
Heat Advisory In Effect
The National Weather Service has a Heat Advisory in place for metro Miami from 11 a.m. to 7 p.m. Friday, warning that the mix of high humidity and daytime heat can be hazardous for outdoor workers and anyone stuck in the sun for long stretches. Forecasters are calling for highs near 90°F with heat-index readings up to 108°F, with southeast winds around 14 mph and gusts that could reach about 20 mph. Officials urge people to take frequent water breaks, stay in air-conditioned spaces when possible, and check on vulnerable neighbors, according to NWS Miami.
Afternoon Storms Could Bring Brief Relief
As the sea breeze pushes inland, showers and thunderstorms are likely to pop up after about 2 p.m., with the best chances inland and to the southwest of the metro. Any storms that fire could deliver gusty winds and brief heavy downpours, but they are not expected to be widespread. Most spots that see rain will pick up less than a tenth of an inch, although slow-moving cells can still cause localized street flooding. Boaters and anyone planning outdoor events should keep an eye on radar and be ready to pause or reschedule if storms roll through.
Cooling Options And Safety Tips
Miami-Dade and the City of Miami run cooling centers and other community locations for people who need a reliable blast of air conditioning. During heat activations, some libraries and parks may open designated cooling areas. If your home does not cool down well, consider heading to a cooling site, drink plenty of water, and avoid strenuous outdoor work during the advisory window. For a full list of local cooling sites and their hours, see Miami-Dade County.
What To Expect Next
This hot, swampy pattern is expected to stick around into the weekend and early next week, keeping overnight lows uncomfortably warm and allowing afternoon heat-index values to routinely climb above 105°F. Scattered afternoon storms will remain the main source of short-lived relief, and forecasters say more heat advisories are possible if the pattern holds.
