South Florida residents are gearing up for another classic summer day filled with intense heat and the possibility of refreshing afternoon thunderstorms. A Heat Advisory has been issued for Miami-Dade and Broward counties, running from 11:00 a.m. to 6:00 p.m. on Friday, August 21, 2026, as temperatures climb into the low 90s with heat index values making it feel even hotter outdoors.
Meteorologists are reminding South Floridians to take the heat seriously and make the most of the season by planning outdoor activities during the cooler morning hours. Staying hydrated, wearing lightweight and light-colored clothing, and seeking shade during peak afternoon hours are all great ways to enjoy the summer while keeping safe.
