San Antonio starts Thursday under lingering morning clouds, but skies clear out for a mostly sunny afternoon with a high near 93°F, light south-southeast wind at 0 to 10 mph, and zero rain chance — so get outdoor errands done early and keep the water bottle full once the sun takes over.
Today’s Setup
The National Weather Service in Austin/San Antonio says clouds move in overnight and hang around through late Thursday morning before burning off into mostly sunny skies. A stray shower or thunderstorm can’t be fully ruled out toward the Coastal Plains southeast of the city if an inverted trough near the Texas coast wobbles our way, but most of San Antonio, including Lackland and Fort Sam Houston, should stay dry with a high near 93°F.
Best Window To Be Outside
Morning, while those clouds are still hanging on, is your coolest and most comfortable stretch — think dog walks along the River Walk or errands before 11 AM CT. Once the clouds clear, afternoon heat builds fast with light wind offering little relief, so save yard work, jogging, or River Walk strolling for after sunset when temps ease back toward the mid-70s.
Heat Risk
No advisory is posted for today, but Friday’s heat index climbs as high as 100°F, so treat today as your warm-up. Pets and kids shouldn’t linger outside during peak afternoon hours, and anyone working outdoors around the bases or job sites should take regular shade breaks.
What To Wear Or Bring
An insulated tumbler 30oz keeps water cold through the afternoon, and an anti-frizz hair serum helps against South Texas humidity. If a pool day is in the cards, the 2-Person Intex Floating Lounge with Cooler is just $24 on Amazon and perfect for backyard cooling off.
Holiday Weekend Events
Ye Live in San Antonio hits the Alamodome on Saturday, July 4, with the forecast calling for a mostly sunny, dry, 95°F day — grab a Ye t-shirt, Ye hoodie, or Ye hat before the show. Same night, Willie Nelson’s 4th of July Picnic and Fireworks lights up Germania Insurance Amphitheater; tickets on SeatGeek if you’re heading out. And on July 6, Joji brings SOLARIS to Moody Center ATX — tickets on StubHub, and a Joji t-shirt makes a solid concert layer once the sun goes down.
Tonight’s Meal Idea
It’s too hot to fire up the stove tonight, so lean into a cold Thai noodle salad, a build-your-own wrap bar, or smoothie bowls — a high-powered blender makes quick work of the smoothies, and that insulated tumbler 30oz keeps drinks cold on the patio. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Friday repeats today’s pattern — morning clouds, afternoon sun, highs in the mid-90s, and a heat index up to 100°F, with an isolated shower or storm possible as far north as the I-35 corridor. Independence Day itself stays dry and sunny near 95°F for the Alamodome show and backyard cookouts, but the NWS expects rain chances to return late Saturday night into Sunday and Monday afternoons as an upper-level disturbance moves in over the Edwards Plateau and Rio Grande Plains — worth watching if your holiday plans stretch into the weekend.
