Miami is waking up to another scorching Wednesday, with temperatures climbing near 90°F and a Heat Advisory already in effect for coastal and metro Miami-Dade and Broward County — keep that insulated tumbler 30oz full and within arm’s reach all day.
Today’s Setup
The National Weather Service is flagging serious heat this morning. By afternoon, the heat index could feel as high as 105°F, with south winds at 6 to 13 mph offering little relief. Skies start sunny across the area, but scattered thunderstorms will fire up after 3 PM ET, developing first over inland Miami-Dade before tracking northeast through Broward. NWS forecasters note that mid-level dry air may limit overall coverage, but low-lying neighborhoods like Overtown and areas along the Palmetto Expressway remain at risk of localized urban and poor drainage flooding. If you’re commuting home through rush hour, add extra time.
One more concern for today: wildfire smoke from active fire in central Miami-Dade County is expected to drift northward and could degrade air quality to hazardous levels for sensitive populations. If you have asthma, heart conditions, or any respiratory sensitivity, stay indoors with windows closed during peak smoke hours.
Best Window To Be Outside
Early morning is your only real window. Head to Crandon Park, Bayfront Park, or anywhere along Biscayne Bay before 10 AM. After noon, the combination of heat and smoke makes conditions genuinely dangerous — especially for children, seniors, and anyone working outdoors.
Events This Week
If you’re looking to escape the heat this week, there’s no shortage of indoor options. Tomorrow night (June 18), The Red Clay Strays play Hard Rock Live in Hollywood — a covered venue means zero weather stress. Find tickets on StubHub before the show fills up.
Juneteenth weekend brings the Miami Marlins hosting the San Francisco Giants at loanDepot park on both June 19 and June 20. The retractable roof handles afternoon storms without missing a pitch, but the parking lots will be scorching — arrive early. Gear up in a Miami Marlins jersey and a Miami Marlins fitted cap, and Get tickets on SeatGeek if you still need seats. Also on June 20, the Josh Groban with special guest Jennifer Hudson show hits Hard Rock Live — perfect air-conditioned refuge from the summer heat.
