San Antonio woke up to bright sun and a chill in the air on Thursday, March 12, 2026, with morning temperatures in the mid 50s. The National Weather Service is calling for a high near 69°F, along with a breezy start to the day before winds ease later this afternoon. The rest of the week stays dry, with a strong warmup into the weekend followed by a sharp cold front early next week.
Afternoon Winds Pick Up
According to the NWS Austin/San Antonio, northerly winds will stay gusty through the morning, and a few spots could briefly flirt with wind advisory levels before speeds drop back to around 5 to 15 mph later today. There are no watches or warnings in effect for the San Antonio area right now, although forecasters did flag a short window of elevated fire weather potential where humidity could fall into the low 20s. It is a good idea to secure loose outdoor items and allow a little extra time for the morning commute while the gusts hang around.
Weekend Warmup And Sunday Front
Temperatures climb quickly, with highs near 78°F on Friday, about 85°F on Saturday, and close to 91°F on Sunday, March 15, 2026. A strong cold front is expected to arrive Sunday evening, which should knock afternoon highs back into the 50s on Monday, along with gusty north winds and chilly morning lows in the 30s across the Hill Country.

If you have outdoor plans, look for warm, dry conditions Saturday and Sunday, but keep an eye on late Sunday timing if your events run into the evening or night.
What To Know This Week
Dry air combined with gusty winds could briefly drop relative humidity into the low 20s along the I 35 corridor this afternoon, creating short lived elevated fire weather conditions. Avoid open burning and think twice about grilling in high risk spots. Tie down patio furniture and secure yard items before the stronger morning winds arrive, and keep checking updated forecasts if you are planning to be outside over the weekend. Look to the latest products from the National Weather Service in case conditions change.
