Miami rolled out of bed to mostly clear skies and swampy humidity on Sunday, April 26, 2026, with temperatures starting in the low to mid 70s and a light southeast breeze. The rest of the day looks warm and muggy, with highs near 83°F and the chance that scattered showers or a few thunderstorms pop up later, mainly away from the coast. If you are banking on sunshine for outdoor plans, keep one eye on the radar, since South Florida storms tend to be hit or miss and can ramp up in a hurry.
Afternoon Storms Possible
The National Weather Service expects showers and thunderstorms to start trying to fire after about 3 p.m., with the best chances across interior neighborhoods where colliding sea breezes often light the fuse on storms. The overall odds of rain during peak afternoon heating sit around 25 to 30%, according to National Weather Service Miami. Any storm that does form could bring brief heavy downpours that cut visibility and make roads slick. Winds should stay on the light side from the south at about 6 to 9 mph, although stronger cells could kick up some gustier pockets.
Stronger Storms Can't Be Ruled Out
The forecast discussion from the Miami office highlights a secondary impulse sliding in Sunday afternoon, which could help a few storms flex a bit more, with the potential for gusty winds and some small hail in the healthiest cells. Widespread severe weather is not on the table, but it is worth keeping tabs on the sky if you are inland, as noted in the NWS forecast discussion. Storm coverage should ease after sunset, with overnight lows settling back into the low to mid 70s. Out on the water, mariners can expect seas around 2 feet or less, though any isolated storm over the local waters could briefly stir things up.
What This Means For Your Plans
It is a good day for flexibility. Toss a lightweight rain jacket in the bag and have a backup plan for late-day outdoor activities. Plenty of neighborhoods will stay dry, but a single passing storm can wash out an hour of your schedule. Beachgoers should stick close to lifeguard stands and pay attention to the flags, since onshore winds and scattered storms can lead to choppier surf and lower visibility. Drivers should slow down anywhere water pools on the road and avoid trying to push through any flooded stretches.
Quick Forecast
Today: High near 83°F with a 25 to 30% chance of afternoon showers or thunderstorms.
Tonight: Any showers should wind down after sunset, with lows around 73 to 74°F. Seas and bay waters stay generally calm at about 2 feet or less through the rest of the weekend.
