San Antonio woke up in a sweat Sunday, with muggy air, mostly cloudy skies and temperatures already near 77°F, while dew points hovered in the low 70s. By this afternoon, the heat is set to crank up to around 92°F, with south-southeast winds that could gust up to 30 mph.
Afternoon Heat And Gusty Winds
The National Weather Service is calling for a hot and breezy day, with highs near 92°F and south-southeast winds of 10-15 mph, gusting to around 30 mph. A stray late-day shower or isolated thunderstorm may pop up, but most neighborhoods should stay dry, with any new rainfall generally under a tenth of an inch.
Monday looks similar but a notch hotter, and heat index values could push into the low 100s in some spots, especially across the Rio Grande Plains and Winter Garden areas, according to the National Weather Service.
Stay Cool And Plan Ahead
If you are spending time outside, try to avoid heavy exertion during the peak afternoon heat, sip water often and grab shade or air-conditioning whenever you can. The San Antonio Metro Health heat plan lists cooling locations and explains how local heat-alert levels work, with libraries, community centers and senior centers often serving as daytime cooling spots.
For localized heat resources or to report heat-related illness, you can call 211 or check the San Antonio Metro Health heat plan.
What To Expect Next Week
Looking beyond the weekend, forecasts show a more active and wetter pattern settling in early next week. Scattered storms are expected to increase Monday night, with showers and thunderstorms likely from Tuesday night into Thursday.
Some storms could drop heavy downpours and cause brief, localized flooding if they move slowly or repeatedly track over the same areas. If you have outdoor plans later in the week, it is worth building in some flexibility and checking updated forecasts and local alerts before you head out.
