San Antonio rolled into Friday, July 24, 2026, under muggy, mostly cloudy skies, with temperatures near 77°F and dew points in the mid-70s making it feel sticky before sunrise. A few lingering showers tied to the remnants of Bertha may hang on until about 7 a.m., but the rest of the day turns partly to mostly sunny with a high near 95°F and heat-index values pushing close to 104°F. South-southeast winds should run about 5-15 mph, with gusts around 20-25 mph, so it could feel a bit breezy during outdoor plans.
Morning Showers, Then Heat
Early Friday brings a shot at rain mainly before 7 a.m., focused along and south of the I-10 and Highway 90 corridor. Most spots that see showers will only pick up a few tenths of an inch, while an isolated thunderstorm could wring out up to around 2 inches in a short burst. By afternoon, the sun is back and so is the heat, with highs near 95°F and heat-index readings topping 100°F, so frequent water breaks and some time in the shade are a smart move.
Nueces River Flooding
Major to moderate flooding is still ongoing along the Nueces River near Asherton, and nearby roads, including parts of FM 190 and Highway 85, remain inundated, according to the NWS Austin/San Antonio. Officials continue to press the basics: do not try to cross flooded roads, and move livestock or property out of low-lying spots where you can. The river is forecast to slowly fall through the weekend, but some crossings and low-lying farms may stay impacted through Saturday, July 25.
Weekend Outlook
Saturday, July 25, and Sunday, July 26, look hot and mostly dry, with highs in the mid-90s and some afternoons feeling like 100°F or warmer once humidity is factored in. Early next week, temperatures edge up a bit more, with highs in the upper-90s and around 100°F possible on Tuesday and Thursday.

Plan Ahead
Hydration is key: bring water, aim for outdoor activities in the cooler morning or evening hours, and keep tabs on road conditions if you are headed toward Dimmit and Zavala counties. If you hit a flooded roadway, turn around and find another route; do not drive through standing or flowing water. Keep pets and livestock sheltered during the peak heat of the day, and check in with local authorities for the latest word on closures or any evacuation guidance.
