Miami woke up to sticky, partly cloudy skies on Monday, June 1, 2026, with temperatures already in the low 80s. The rest of the day will stay hot and humid, with highs near 88°F, and the atmosphere primed for showers and thunderstorms after 1 p.m.
Afternoon Thunder Risk
Showers and thunderstorms are most likely after 1 p.m. Monday, June 1, with forecasters putting the chance of rain around 70% and new rainfall amounts of roughly a half to three-quarters of an inch possible. A few storms could bring brief heavy downpours and localized street flooding, and heat index values could climb toward 100 to 101°F in inland neighborhoods. Wind will be light from the southwest this afternoon, generally 5 to 8 mph, then shift direction later in the week, according to the National Weather Service Miami.
Midweek Outlook
Rain chances increase by midweek. Wednesday and Thursday are currently expected to be the wettest days as a slower weather pattern funnels more moisture into South Florida. Daytime highs should slip into the low 80s on those days, but rain will be more widespread and persistent. Boaters and beachgoers should plan on stronger onshore winds and choppier seas later in the week.
Heat And Commute Tips
With heat indices near or above 100°F in spots, it is a good day to keep water handy and avoid extended outdoor work during peak afternoon hours on Monday, June 1. If you need relief from the heat, Miami-Dade County maintains a list of public cooling sites and community centers. Check Miami-Dade County for locations and hours. Expect scattered downpours to slow evening commutes, so leave extra time and watch for standing water on lower-lying roads.
Tonight
Showers and thunderstorms are likely early Monday night, then should taper off after mid-evening, with lows near 80°F. Keep umbrellas within reach for any outdoor plans this evening, as lightning and brief heavy rain remain the main hazards overnight.
