Miami woke up to a murky cocktail of haze, smoke and humidity on Tuesday, June 23, 2026, with temperatures already stuck in the low 80s before most people finished their first coffee. Patchy smoke is hanging over parts of the metro, and the rest of the day is set to be plain hot, with forecast highs near 90°F and heat indices well over 100°F. It is not exactly ideal weather for a long jog or a sunbaked errand run.
Heat Advisory In Effect
The National Weather Service has a Heat Advisory in place for coastal and metro Miami-Dade and Broward counties from 11 a.m. to 6 p.m. on Tuesday, June 23. Forecasters expect heat index values to climb as high as 105°F, with actual afternoon highs near 90°F and only limited overnight relief as coastal lows linger in the low 80s. For official details and hourly updates, head to the National Weather Service Miami.
Where To Cool Off
To help people ride out days like this, Miami-Dade County operates a network of cooling sites, including libraries, community centers and park facilities, during the heat season. Anyone who needs air conditioning or a place to hydrate can use them, although hours and specific locations vary, so it is smart to call ahead if possible. You can find the latest list of neighborhood locations and hours at Miami-Dade County cooling sites.
Haze, Smoke And Pop-Up Storms
Patchy smoke from nearby fires is cutting visibility in some spots, and an Air Quality Alert for fine particulates is in effect. People with asthma or heart and lung conditions are urged to take it easy outside or move activities indoors for the day.
Isolated to scattered showers and thunderstorms are possible this afternoon, mainly inland. Any stronger storm could deliver frequent lightning, brief downpours and gusty winds, a quick jolt of weather whiplash on an otherwise steamy day.
On top of that, a plume of Saharan dust is sliding in and helping to keep the skies hazy. For changing conditions, updated advisories and the latest forecast, check in with the National Weather Service Miami.
