Miami starts Monday, May 18 under partly cloudy skies with a high near 84°F — but a 30% chance of afternoon showers and thunderstorms, mainly between 11 AM and 2 PM ET, means you’ll want a compact travel umbrella within reach before heading out. Check the Miami weather forecast for live radar updates throughout the day.
Today’s Setup
An upper-level low parked near the Bahamas is funneling in a brisk east wind around 16 mph with gusts up to 22 mph, boosting instability across South Florida. The National Weather Service says scattered storms will focus mainly on SW Florida, though an isolated storm is possible across the metro. Your cleanest outdoor window is before 10 AM ET — enjoy a morning walk along South Beach or through Coconut Grove before the atmosphere loads up. Precipitation chances climb to 40% overnight with another storm batch possible between 10 PM and 4 AM ET, so wrap up patio time before dark.
Rip Current Warning — Read This First
The National Weather Service has issued a HIGH RISK of rip currents along the east coast of South Florida through at least Tuesday evening. That persistent east wind is driving dangerous surf from Miami Beach northward through Sunny Isles and beyond. Swim only in lifeguarded areas, and if caught in a rip current, swim parallel to shore — not against it. Today is a wade-in-the-shallows day, not a swim-out-far day.
What To Wear or Bring
Toss a packable rain jacket in your bag for any midday run through Brickell or downtown — storms can pop fast and drench you before you reach cover. It’s still warm and humid, so light layers work best. Sunny breaks will appear between cells, so your SPF 50 sunscreen still earns a spot in your bag; 84°F and humidity is a burn risk even on a cloudy afternoon.
Marlins at loanDepot Park + Weekend Events
The Miami Marlins open a four-game homestand against the Atlanta Braves tonight at loanDepot park, running through Thursday, May 21. The stadium’s retractable roof takes the rain factor out of the equation, so game nights this week should be comfortable regardless of what the sky does outside. Show up in style with a Miami Marlins jersey or Miami Marlins fitted cap — and if you haven’t locked in seats, Get tickets on SeatGeek before first pitch.
Looking toward the weekend: Reggae Fest Presents Alkaline takes Kaseya Center on Friday, May 22, and the Carlos Vives - Tour Al Sol concert follows at Kaseya Center on Saturday, May 23. Find tickets on StubHub while they’re still available — both shows land mid-week in what looks like an unsettled forecast pattern, so indoor venues are a smart call.
Tonight’s Dinner
Stormy afternoon energy is a perfect excuse to let the kitchen do the heavy lifting. Load a programmable slow cooker with chili or black bean soup before you leave the house and come home to dinner ready and waiting. Prefer stovetop? An enameled cast iron Dutch oven is built for exactly this kind of low-and-slow beef stew weather. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Tuesday mirrors today — high near 84°F, east wind around 15 mph, and a 40% storm chance. The National Weather Service says rain chances will remain elevated through mid-week as the upper-level low lingers near the Bahamas. The rip current risk stays high through at least Tuesday evening.
