Orlando is cranking up the thermostat again on Tuesday, July 21, 2026, with mostly sunny skies and a high near 95°F. Thick humidity will push heat-index values into the low 100s. There is a slight chance of scattered showers and thunderstorms this afternoon, mainly between about 2 p.m. and 4 p.m., with south-southeast winds around 10–15 mph and gusts up to 25 mph. Any storm that does bubble up could bring frequent lightning and brief heavy downpours, so it is smart to keep an indoor backup plan for any outdoor meetups.
Afternoon Storms And Gusts
The National Weather Service in Melbourne expects isolated to scattered storms, most likely where sea-breeze boundaries collide across the peninsula this afternoon. Most showers should be brief, but forecasters note that stronger cells can pack frequent lightning and stronger wind gusts. The forecast calls for gusts up to about 25 mph under typical conditions, with locally higher gusts possible in the more intense storms. Activity should wind down after sunset, leaving mostly clear skies and lows near 77°F.
Why Winds And Rain Are Shifting
Tropical Storm Bertha in the northern Gulf is helping maintain a south-southeast flow over east-central Florida, which is allowing slightly drier air to creep north and trim rain chances through Thursday. That setup is expected to stick around through the work week, with moisture then increasing again this weekend and into early next week so afternoon storm chances return toward more typical levels by Saturday. Daytime highs will hover in the mid 90s, which means heat-index values will climb above 100°F across much of the area each afternoon.
Plan Ahead And Local Resources
Orange County is keeping its heat safety playbook active, with a list of cooling locations that includes libraries, recreation centers and splash pads. The county will also provide free LYNX bus rides to those sites when the heat index reaches 103°F. Check the full guidance and location list on the Orange County Newsroom.

Boating And Commute
Boaters and small-craft operators should expect choppy conditions this afternoon, with winds and 2–4-foot seas making for a rougher ride. On land, brief downpours under any storm could trigger soggy slowdowns for the evening commute. Build in some extra time, take it easy on wet roads and avoid driving through any flooded spots.
