Miami woke up into a wall of humidity on Wednesday, June 10, 2026, with temperatures around 80°F at Miami International Airport, dew points near 75°F, and air that felt downright oppressive. Mostly cloudy skies this morning will be paired with an east breeze that strengthens through the day, and highs are expected to top out in the mid 80s. There is a slight chance of showers and a few thunderstorms from late morning into early afternoon, so a light rain jacket or umbrella is not a bad idea if you are headed out. Heat indices are forecast to reach into the low to mid 100s through the end of the week, so plan for extra breaks if you need to be outdoors.
Afternoon Storms Could Clip Outdoor Plans
Forecasters call for a slight chance of showers and thunderstorms between about 11 a.m. and 2 p.m. Wednesday, with a high near 86°F and east winds around 10 to 13 mph. Official rain chances sit near 20%. Most activity should be typical early summer storms, capable of brief heavy downpours and gusty winds, although an isolated severe storm cannot be ruled out. If you have outdoor plans in that late morning to mid afternoon window, keep a backup plan handy and stay alert for lightning and sudden wind shifts, according to the National Weather Service Miami.
Heat And Beach Impacts
Humidity will pin overnight lows near 80°F and make afternoons feel hotter than the thermometer suggests, with heat indices in the low to mid 100s likely. That raises the risk of heat exhaustion for people working or playing outside without shade or hydration. Along the Atlantic beaches, a moderate rip current risk continues. Seas are generally around 2 feet or less but can build near any storms that roll through, so stick close to lifeguard stands and follow posted flag warnings. The City of Miami maintains a list of cooling centers and public air conditioned spaces if you need a place to cool down; you can find the list from the City of Miami.
What To Do Today
Keep water with you, ease up on intense exercise during the midday heat, and, when you can, shift outdoor plans to the morning or evening. Through the late morning and early afternoon, watch the sky and local radar for building showers, and get off the water or beach if thunderstorms develop nearby. If you or someone around you starts to feel faint, dizzy, or very weak, move to shade or air conditioning, sip cool fluids, and call 911 if symptoms get worse instead of better.
