Tampa is starting Saturday clear and already sticky, with temperatures around 81°F and humidity near 91% before sunrise. Sunshine will dominate most of the day, but the heat index could reach 103°F as the thermometer climbs to about 94°F. Rain odds stay low today, making this the easier half of the weekend for outdoor plans—provided you beat the heat.

Mostly Sunny Saturday, With Serious Heat

A south-southwest breeze between 2 and 10 mph will offer only modest relief as temperatures rise through the afternoon. The National Weather Service Tampa Bay Ruskin office says conditions will remain hot and humid, though no watches or warnings are posted for Tampa or the Gulf waters.

Sunday Brings The Weekend’s Better Storm Chance

Sunday will be slightly cooler, with a high near 92°F and heat-index values reaching about 101°F. Scattered showers and thunderstorms are most likely between 7 a.m. and 4 p.m., with a 50% chance of rain before skies turn partly cloudy Sunday night and temperatures settle near 77°F.

Drier Monday And Tuesday, Then Rain Chances Rebuild

Monday and Tuesday look like the week’s drier stretch, with highs around 92°F to 94°F and only scattered or isolated afternoon storms. Rain chances rise again Wednesday through Friday as highs reach the mid-90s, climbing from 40% Wednesday to 50% Thursday and 60% Friday.

Heat Still Matters Even When Rain Does Not

Even without an advisory, the combination of heat and humidity can make errands, exercise and outdoor work feel harder than the thermometer suggests. Drink water, take breaks in shade or air conditioning, and never leave children or pets in a parked vehicle.
