San Antonio woke up to a cloudy, muggy blanket of air this morning, with temperatures near 70°F at about 5:10 a.m. CDT on Tuesday, March 31, 2026. Skies are expected to break into partly sunny conditions this afternoon, sending the high to around 89°F. South-southeast winds of 5–15 mph, with gusts up to 25 mph, will keep things on the breezy side across the city.
Afternoon Heat Cranks Up With Gusty Winds
The warmest stretch of the day will be this afternoon, when the forecast high of about 89°F could feel closer to the low 90s in some inland neighborhoods. The south-southeast breeze will strengthen as the day goes on, with gusts up to 25 mph in more exposed spots. National Weather Service forecasters say a thermal ridge will keep temperatures running above normal through Saturday, so the early spring warmth is not going anywhere just yet.
Storm Chances Build Wednesday Night Into Thursday
Rain chances pick up Wednesday night into Thursday, with a slight chance of showers and a few thunderstorms after about 1 a.m. on Thursday, April 2. Thursday itself brings higher odds for storms, especially in the afternoon, with scattered showers and some pockets of heavier rain in the mix. Gusty south-southeast winds may reach 30 mph inside stronger storms, and a few stronger cells cannot be completely ruled out.
Stormy Weekend On Deck
A stronger system is on track to move in Friday night into Saturday, bringing the best shot at more widespread showers and thunderstorms through the weekend. Saturday’s high is forecast near 83°F with a wet, breezy setup and showers likely Saturday night. After that, temperatures tumble, with Easter Sunday, April 5, shaping up to be noticeably cooler and below average for this time of year.

Plan Ahead
This is a good week to keep outdoor plans flexible. Tie down or bring in lawn furniture, keep rain gear handy for evening plans, and be ready for slower travel if heavier cells roll through at the wrong time. Stay tuned to updated forecasts and sign up for weather alerts so phones and official NWS messages can give you the latest timing if storms start to strengthen. If you have large outdoor events on the books for the weekend, it is worth lining up an indoor option or a backup date now.
