Miami is starting sunny but turning stormy today, with a high near 91°F, a 45% chance of afternoon and evening thunderstorms, and heat index values climbing as high as 108°F — get outdoor errands and beach time done before lunch, because the National Weather Service in Miami says the risk window opens after 2 PM.
Today’s Setup
High pressure is weakening today, letting deeper tropical moisture stream into South Florida. The Area Forecast Discussion notes PWATs near 2.0-2.3 inches and CAPE around 2000 J/kg — plenty of fuel for scattered to numerous storms this afternoon and evening, favoring interior and eastern neighborhoods. Winds run southwest at 6 to 14 mph. Tonight stays muggy with a low around 83°F and a lingering 40% storm chance before 9 PM.
Best Window To Be Outside
Morning through early afternoon is your safest bet — think a walk in Coconut Grove or a paddle off Key Biscayne before the cap breaks. Once storms fire after 2 PM, the NWS warns any cell could bring strong wind gusts, frequent lightning, heavy downpours, and small hail. Slow-moving storms also raise a localized flooding risk on low-lying streets, so keep an eye on radar if you’re driving through Brickell or the Grove late afternoon.
Weekend Games & Events
Tonight’s outdoor show, Lynyrd Skynyrd at iTHINK Financial Amphitheatre, falls right in that late storm window — pack ponchos, not umbrellas, given the wind gusts in play. Saturday brings the World Cup Third Place match between France and England at Hard Rock Stadium, with a much lower 20% storm chance and a high near 89°F, so tailgating conditions look far better than today’s. Get tickets on SeatGeek or Find tickets on StubHub, and pick up Official team gear on Fanatics before kickoff. Prefer music indoors? Megan Moroney plays Amerant Bank Arena Saturday, where weather won’t be a factor.
What To Wear Or Bring
With heat index near 108°F, hydrate constantly — an insulated tumbler 30oz keeps water cold on the sideline or the sand. Beachgoers should grab quick dry swim trunks for a quick morning swim, and if you’re grilling before storms roll in, a portable propane grill lets you get lunch done early. Storms plus gusty wind also mean it’s worth securing loose patio items with outdoor furniture covers. If you’re tackling yard work first, the EGO Power+ 56V battery deal is worth a look before you mow ahead of the afternoon storms.
With heat index values this high, cooking indoors over a hot stove isn’t appealing — a cold Thai noodle salad or smoothie bowls made in a high-powered blender beat standing over a grill in the heat. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Saturday looks drier overall — mostly sunny with a high near 89°F and just a slight chance of storms after noon, dropping to a low around 83°F Saturday night with mostly partly cloudy skies and a low 8% rain chance. The active, moisture-rich pattern continues into the weekend, so keep storm plans flexible and check back before heading to Hard Rock Stadium Saturday.
