San Antonio is looking at a mostly sunny Saturday with a high near 95°F and heat index values as high as 100 degrees, according to the National Weather Service — so get your outdoor plans done early and treat the afternoon as shade-and-water time.
Today’s Setup
A mid-level ridge parked over the Four Corners into the Texas and Oklahoma panhandles is steering a light southerly flow into the Alamo City, and forecasters say that means a seasonably hot, humid pattern through the weekend. Expect some low clouds and stratus to linger into the morning from residual soil moisture before skies clear out to partly-to-mostly sunny by afternoon. Winds stay light out of the south-southeast at 5 to 10 mph, and rain chances are essentially zero.
Best Window To Be Outside
Morning is the move — before 10 or 11 a.m., while temperatures are still climbing out of the overnight low near 77°F. A walk along the River Walk or a loop near Fort Sam Houston or Lackland stays comfortable early, but by mid-afternoon the heat index near 100 makes prolonged sun exposure rough on kids, pets, and anyone in uniform training outdoors. Fishing around Hill Country lakes is also best tackled at first light.
Heat Risk And Water Levels
Heat is the headline risk this weekend, not storms — no severe weather is expected and the excessive rainfall outlook doesn’t flag South-Central Texas today. One item to watch: the Nueces River at Asherton is still slowly receding within moderate flood stage, a reminder that Flash Flood Alley conditions can linger even without new rain, so stay cautious near area waterways.
What To Wear Or Bring
Light, breathable clothing, sunscreen, and constant hydration are non-negotiable. Anglers heading out early should grab the Score a UPF 50+ Sun Hoodie for Just $5 This Fishing Season deal for sun protection on the water, and a soft cooler backpack keeps drinks cold on the go.

Around Town This Week
Staying cool indoors tonight? Hot Wheels Monster Trucks Live Glow-N-Fire roars into Frost Bank Center this evening — grab tickets on SeatGeek. Frost Bank Center also hosts Lionel Richie and Earth, Wind & Fire on July 28; read our full concert weather preview and find tickets on StubHub, plus a Lionel Richie t-shirt for the show. Hamilton (Touring) opens at the Majestic Theatre San Antonio on July 29 — both are indoor venues, so heat won’t be a factor once you’re inside.
Dinner Idea
With dry, sunny skies through the evening, tonight is prime grilling weather — burgers, steaks, or grilled chicken with corn on the cob all work well. An instant-read meat thermometer and a grill brush and scraper set make cleanup and doneness a lot easier in this heat. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Sunday climbs even hotter, with a high near 96°F and heat index values up to 102. The ridge holds firm into next week, keeping South-Central Texas rain-free with highs ticking up a few more degrees by week’s end, per the National Weather Service.
