Miami rolls into Thursday, May 14, 2026, on the steamy side, with clear skies, early morning temperatures near 77°F, and humidity already sticking around. It will be a hot one, with highs around 86 to 87°F under mainly sunny skies and only a slight shot at a shower or isolated thunderstorm later this afternoon.
Afternoon Storm Risk
A fading frontal boundary and a possible surface low off the east coast are just enough to stir the pot. That setup raises the odds for a few pop-up showers and maybe an isolated strong storm after about 2 p.m., especially where the sea breeze bumps into inland air. Most neighborhoods should stay dry, but the National Weather Service in Miami pegs the chance of afternoon showers at roughly 20 to 30 percent and notes that any storm that does form could briefly kick up gusty winds and heavy rain.
On the water, Atlantic seas are expected to run about 2 to 4 feet, with Gulf waters closer to 2 feet. Boaters are urged to stay alert, since conditions can flip quickly near any thunderstorm. These details come from the National Weather Service in Miami.
Beaches and Boaters
Beachgoers should keep an eye on the lifeguard flags and skip solo swims. The City of Miami Beach Ocean Rescue posts day-of conditions and flag warnings, so a quick check before you head out can save you some trouble.
Boaters can plan on a light to moderate breeze with generally manageable seas, but things can get choppy around any storm. A last-minute look at local beach or marina updates is a smart move before pushing off the dock.
This Weekend
Looking toward the weekend, the forecast settles into a classic early summer pattern for South Florida. Expect afternoon sea-breeze storms to bubble up inland, along with coastal showers popping up overnight, and daytime highs in the upper 80s to low 90s.
The National Weather Service in Miami expects daily afternoon storm chances to increase through the weekend as a weak upper-level pattern combines with an easterly flow that taps into Gulf and Caribbean moisture.
