San Antonio woke up to mostly clear skies and a muggy start in the low 70s, the kind of morning where you notice the air before you check the temperature. The rest of the day trends warm, with a high near 91°F and a light south-southeast breeze. Humidity will keep things feeling sticky, especially early, so plan any outdoor time with that in mind.
Afternoon Outlook
As the day wears on, the sun takes over and helps push temperatures into the low 90s, with afternoon highs expected to top out near 91°F. Morning clouds and a few patchy fog spots along the coastal plain should fade, leaving San Antonio under partly to mostly sunny skies. Southeast winds stay on the gentle side, generally around 5-10 mph, so do not expect much help from a cooling breeze.
Storms Return Midweek
Rain chances edge back into the picture on Tuesday with a slight, roughly 20% chance of afternoon storms. That is just the warmup. Storm odds climb on Wednesday, Thursday and Friday, when showers and thunderstorms become more likely. Some pockets of rain could be locally heavy at times, but widespread flooding is not expected. Most of the action looks geared toward the afternoon and evening hours, so keep an eye on the sky and have a backup plan for outdoor events, according to the National Weather Service Austin/San Antonio.
Beat The Heat
The city keeps an interactive list of libraries, community centers and senior centers that residents can use as cool-down spots during hot stretches. You can find locations and hours on the City of San Antonio page or call 3-1-1 for assistance. If you are relying on public transit to get there, check VIA for any service alerts before you head out.
Bottom line: expect warm, humid conditions today and Monday, followed by a shift to more unsettled, storm-friendly weather from Tuesday through the weekend. Check the forecast before you leave home each day, and keep both a water bottle and an umbrella handy for midweek plans.
