San Antonio started Wednesday, March 25, 2026, under a blanket of low clouds and patchy fog, but the cool look is not fooling anyone. Forecasters expect temperatures to race into the upper 80s and flirt with 90°F by mid to late afternoon. Morning readings sat in the upper 60s to low 70s with classic springtime mugginess, and skies are expected to turn mostly sunny by late morning. If you have outdoor plans, plan on a noticeably hotter afternoon than what we have seen earlier this month.
Afternoon Winds Pick Up
South southeast winds are set to flex a bit this afternoon, generally running 5 to 15 mph with gusts around 20 to 25 mph, especially in more open parts of the city. The National Weather Service is calling for this breezy pattern to hang on through Thursday, so it is a good idea to secure patio furniture, trash bins, and any other light items prone to flying away. Stronger gusts late tonight could briefly make driving tricky for high profile vehicles on exposed bridges and elevated roadways.
Fire Weather And Burn Ban
Forecasters warn that elevated fire weather is possible from Wednesday, March 25 through Friday, March 27, 2026, mainly across the Rio Grande plains. Drier afternoons paired with gusty winds could help any small fire spread faster than usual. Bexar County remains under a countywide burn ban that was extended in early February and runs through Monday, May 11, 2026. Violating the order is a Class C misdemeanor and can carry fines up to $500, according to KSAT. Residents are urged to skip open burning and use extra caution with grills, yard debris burning, and any fireworks while winds stay on the gusty side.
Rest Of The Week
High temperatures are expected to hover near 90°F through Friday, March 27, 2026, with very little rain in the cards. A modest cooldown should arrive Saturday, March 28, when highs dip to the mid 80s. Sunday, March 29 looks mostly sunny and dry with highs again in the mid 80s, before readings climb back toward the upper 80s and low 90s early next week. Anyone with outdoor events or travel later in the week will want to keep an eye on updated forecasts.
Plan Ahead
Make sure to drink plenty of water if you are working or exercising outside, and check on older neighbors and family members who do not have air conditioning as the heat ramps up. Secure lightweight outdoor items, postpone any open air burning while gusty winds persist, and keep tabs on the full forecast through the National Weather Service if conditions begin to change.
