San Antonio is gearing up for a hot, breezy Thursday, March 26, 2026, with mostly sunny skies and highs near 89°F. A muggy start in the morning will give way to drier air by afternoon as south-southeast winds kick up. Gusts into the mid-20s (mph) could have patio furniture and tents on the move, so keep outdoor setups and plans flexible.
Afternoon Winds Pick Up
South-southeast winds are expected around 5 to 15 mph, with gusts up to 25 mph and a daytime high near 89°F, according to the National Weather Service Austin/San Antonio. Forecast discussion from the office notes that relative humidity will drop into the mid-20s to mid-30s this afternoon and again Friday. That dry air, combined with gusty winds, could lead to locally elevated to near-critical fire weather in some spots, even though fuels are not unusually dry. It is a good day to secure loose yard items and go easy on outdoor grilling or any spark-producing work during the windiest hours.
Friday Front and Weekend Outlook
A cold front is expected to move through on Friday, March 27, 2026, turning winds northwesterly and bringing cooler temperatures for Saturday, with highs near 80°F. Rain is not currently expected with the front, but timing could still shift, so it is smart to keep weekend outdoor plans a bit flexible. By Sunday and early next week, warm southerly flow returns, and highs are forecast to climb back into the upper 80s and low 90s by midweek.
How To Prepare
Hydrate throughout the day, and if you can, schedule yard work or other strenuous chores for the morning or evening instead of the hottest, windiest stretch. Tie down or stow lightweight outdoor furniture and decorations before the gusts ramp up. For local heat safety guidance and information on community cooling resources, check the City of San Antonio. If you are planning controlled burns or using tools that can spark, it is best to hold off while humidity is low and winds are gusty.
