Tuesday, July 21, 2026, is starting off sticky in Tampa. Skies are partly cloudy, the humidity is already uncomfortable, and temperatures hover near 81°F. The National Weather Service has flagged a high risk of rip currents along Gulf beaches through 8 p.m., and bands of showers with scattered thunderstorms are expected to roll through into the afternoon. Highs should reach around 93°F, with heat index values topping 100°F, and gusty south winds could turn both boating and beach swimming into a hazardous proposition.
Afternoon Storms And Sweltering Heat
Scattered showers and thunderstorms are most likely from about 9 a.m. to 4 p.m., as sea-breeze boundaries spark waves of storms. The high will land near 93°F, with the heat index pushing roughly 100 to 103°F. Expect south winds of 5 to 14 mph, with gusts up to 24 mph. Any storms that pop could unleash brief heavy downpours, dropping a tenth to a quarter inch of rain in spots and quickly cutting visibility on wet roads. If you are planning to be outside, be ready to duck for cover. NWS Tampa Bay Ruskin
Beach Dangers And Rough Marine Conditions
Rip currents will be a serious concern along beaches in Pinellas, coastal Hillsborough, Manatee and Sarasota counties through 8 p.m. Tuesday, July 21, 2026. Swimmers are urged to pay close attention to lifeguards and warning flags. Out on the water, conditions are no friendlier: choppy, elevated seas and unsettled weather have triggered Small Craft Advisories across much of the coastal waters. Storm bands nearshore may bring sudden wind gusts around 40 mph. If you have boating or nearshore plans, it may be wiser to postpone or stay inside protected harbors until the weather settles down.

Bertha’s Nearby Spin And The Days Ahead
Tropical Storm Bertha is spinning in the eastern Gulf, well west of Tampa but close enough to sling extra moisture into the region and fuel those passing bands of rain. Forecasters are tracking its path and strength for potential broader impacts around the Gulf. As Bertha shifts westward away from the peninsula from Tuesday night into Wednesday, some drier air should move in, afternoon storm coverage is expected to shrink, and high temperatures are forecast to climb back into the mid 90s later in the week. For the latest storm position, check the National Hurricane Center, and see our July 19 storm briefing for the prior local overview.
How To Stay Out Of Trouble
If you are heading to the shore, skip unguarded beaches, keep kids within arm’s reach in the water, and listen to lifeguard instructions. On the roads, be ready for brief heavy rain and reduced visibility in fast-moving downpours. Boaters should delay trips or stick to protected harbors until advisories expire. With heat index values soaring in the afternoon, prolonged outdoor exertion will be risky for older adults and pets, so keep water and shade close and take it slow.
