San Antonio woke up clear and crisp this morning, with temperatures sitting in the mid 40s at Kelly Field (KSKF). Sunshine will do its thing today, pushing highs into the upper 70s to around 80 degrees. The warmup keeps building through the weekend, with the city climbing into the 80s on Saturday and topping out near 92 degrees on Sunday, March 15, 2026. Then a strong cold front barges in Sunday evening, flipping conditions to much cooler and blustery by Monday, March 16, 2026.
Heat Then A Swift Drop
High temperatures will climb quickly through the weekend, with readings near 80 degrees Friday, the mid 80s Saturday and roughly 92 degrees on Sunday. A dryline and persistent southerly flow are teaming up to pump warm, dry air across South Central Texas.
The front is expected to move through late Sunday and bring a sharp temperature drop along with a hard shift to northerly winds of 20 to 30 mph, with gusts that could reach 40 to 50 mph. Forecasters note that a Wind Advisory is possible, and that near critical to critical fire weather conditions are likely in portions of the Hill Country and some western counties, according to the National Weather Service Austin/San Antonio.
Local Fire Restrictions
Bexar County already has an outdoor burn ban in effect, and county officials are urging residents to hold off on any open burning while vegetation stays dry and winds ramp up. If you were planning yard cleanup, a brush pile burn, or even an overenthusiastic grilling session, it is safer to delay until the fire danger backs off and you have checked what is currently allowed. For up-to-date local rules and guidance, head to the Bexar County Fire Marshal.
What To Do
Before the front arrives Sunday evening, secure patio furniture, trash cans and any lightweight items that could turn into airborne projectiles once those gusty north winds kick in. If you are out and about late Sunday into Monday, give yourself extra travel time when winds are strongest.
Plan for a noticeably cooler feel Monday morning and dress in layers so you are not caught off guard after the weekend heat. Keep weather alerts enabled on your phone as forecasts are fine-tuned over the weekend, check official forecasts before any travel, and avoid outdoor burning until conditions improve and local authorities give the all clear.
