San Antonio rolled into the day under gray, sticky skies, with temperatures stuck in the mid-70s and humidity doing the heavy lifting. Things will heat up fast. Forecasters are calling for mostly sunny skies and an afternoon high near 94°F, with a heat index pushing close to 102°F. South to southeast winds will stay on the breezy side, and overnight lows in the mid-70s will not offer much of a cooldown for anyone without air conditioning.
Afternoon Heat And Gusty Winds
By mid-afternoon, the sun takes over. Expect mostly sunny conditions with highs around 94°F and heat-index readings peaking near 102 to 103°F between about 2 and 6 p.m. South winds around 10 to 15 mph, with gusts up to 25 to 30 mph, are in the forecast, especially along and east of I-35. Those gusts could send lightweight items tumbling and make pop-up shade structures and canopies a bit dicey if they are not secured.
There are no watches or warnings in effect for Bexar County this morning. A subtropical ridge is keeping things hot and dry into early next week, according to NWS Austin/San Antonio.
Plan Around The Heat
Outdoor plans are not off the table, but you will want to time them smartly. Try to avoid strenuous activity during the hottest part of the afternoon and shift events to earlier in the morning or later in the evening when you can. If you do not have reliable air conditioning, the City of San Antonio offers an interactive map of cooling locations and heat safety tips. Residents can call 311 or visit the city heat hub for locations and hours, according to the City of San Antonio.
Check in on vulnerable neighbors, keep pets out of the worst of the afternoon sun, and tie down or bring in loose outdoor furniture and event canopies before the gustiest period of the day.
The warm, dry pattern holds through the weekend, with high temperatures sticking in the mid-90s. We will share updates if the National Weather Service issues any watches or advisories. Until then, stay hydrated and grab frequent breaks in cool, shaded, or air-conditioned spots.
