From June 25 to 28, 2026, Southwest Florida faces a stubborn, oppressive heatwave, according to the National Weather Service. Daytime highs will linger in the low-to-mid 90s, while humidity ramps up the heat index, so it’ll feel more like 103 to 111 degrees. Those peak “RealFeel” temperatures should hit hardest from late morning through afternoon, especially between 11 a.m. and 5 p.m.
Expect high temperatures between 92 and 95 degrees, whether you’re inland or along the coast. The humidity isn’t backing off, so the air will feel stiflingly hot, well over 100 degrees for most of the day.
Afternoon and evening storms are in the mix, too. These aren’t all-day washouts, but those scattered thunderstorms should bubble up inland and then drift toward the coast, sometimes unloading heavy rain in a quick burst.
Sun exposure is dangerous under these conditions. The UV Index will hit extreme levels, with numbers around 13, so skin can burn fast if you’re outside without protection.
Because the mix of heat and humidity makes heat exhaustion and heat stroke a real risk, expect the National Weather Service to issue Heat Advisories for the weekend. Don’t brush these off; take the warnings seriously and look out for yourself and anyone else stuck in this heat.
Tips for Beating the Heat
Surviving Florida’s brutal heat isn’t just about comfort; it’s about staying safe.
Start with water.
Don’t wait until you’re thirsty; sip water all day. Skip the sodas, coffee, and alcohol; they just make dehydration worse.
Stick to light, loose clothing, and go for pale colors that reflect the sun.
A wide-brimmed hat helps shield your face, and if you’re heading out, use sunscreen, at least SPF 30. Plan anything strenuous for early morning or after sunset, when the sun isn’t so unforgiving. Between 10 a.m. and 7 p.m., the outside heat can do actual harm. If you have to be outdoors, rest often in the shade, and cool off with a damp cloth around your neck or wrists.
While inside, don’t let the sun bake your living space.
Shut the blinds or curtains during the day. If you lose power or your place is too hot, find somewhere air-conditioned, like a mall, library, or movie theater. Never leave kids or pets in parked cars, even for a minute.
Take care of your animals, too.
Make sure they always have cool water and a shady spot, and check pavement before walks, as it gets hot enough to burn paws.
Watch for signs of heat exhaustion.
Signs to look for are heavy sweating, muscle cramps, pale skin, nausea, and dizziness. Move quickly to a cooler spot and use wet cloths to lower body temperature. If someone has a high fever (above 103°F), flushed or dry skin, a rapid pulse, confusion, or loses consciousness, that’s heat stroke. Call 911 immediately. Don’t take chances with the heat.
