Wednesday, Feb. 25, 2026 — San Antonio started the day cool and calm in the low 50s, but the quiet morning will not last long. Temperatures are expected to rocket up to around 88°F this afternoon under mostly sunny skies, with a south-southwest breeze helping to dry things out. By late week, that mix of warmth, dry air and gusty winds will bump up the fire danger, especially in western and rural parts of the county.
Afternoon Heat and Winds
The National Weather Service is calling for a high near 88°F on Wednesday, with south-southwest winds around 5 to 10 mph and afternoon humidity dipping into the 20s in some areas, according to NWS Austin/San Antonio. The late afternoon commute should be mostly sunny, but expect some punchy gusts that could reach 20 to 25 mph in more exposed corridors. By tonight, temperatures slide into the upper 50s as the breeze eases.
County Rules And How To Stay Safe
According to Bexar County's burn ban order, outdoor open burning is off the table while the ban is in effect, so residents should cancel any planned burns and avoid activities that might spark dry grass or brush. The county order also notes that violations can be enforced as a Class C misdemeanor with fines, so it is smart to be extra cautious with power tools, trailers and any hot work.

Thursday's Fire Weather Threat
A dry front is expected to move through on Thursday, and spots ahead of the boundary could briefly spike toward or into the lower 90s before cooling down behind it. As the front passes, winds shift to the north and become breezier while humidity drops, a combo the National Weather Service says could lead to near-critical fire weather conditions across parts of South-Central Texas. If you have outdoor plans or burn permits later this week, it is a good idea to stay tuned to updated forecasts and any local advisories over the next 48 hours.
