San Antonio, Texas – A blistering heat wave returns to San Antonio this Wednesday, July 30th, with temperatures soaring to near 100°F and roadways like Loop 410 and I-10 expected to feel the brunt of the summer sun. Afternoon highs combined with minimal wind will create stifling conditions, prompting city officials and health experts to urge residents to limit outdoor activity and stay hydrated.
According to the National Weather Service, sunny skies and a steady southeast breeze of 5 mph will dominate the area Wednesday, pushing “feels-like” temperatures into the triple digits. Public health officials warn that heat exhaustion is a serious risk, especially for children, seniors, and outdoor workers. Drivers should use caution as extended heat can cause pavement and tire blowouts, particularly along busy corridors like I-35 and Loop 1604.
Neighborhoods across Bexar County will see little relief at night, with lows only dropping to the upper 70s. Air conditioners will be working overtime—be sure to check on neighbors and never leave children or pets in vehicles. Water usage and electricity demand may spike, so local utilities recommend conserving power during peak afternoon hours.
Heading toward the weekend, San Antonio faces slightly cooler but still above-average highs near 97°F on Friday, August 1st, with a 20 percent chance of thunderstorms by late afternoon. Outdoor events and travel plans should include backup options for shelter and water breaks. The heat wave continues into early next week, so it’s crucial to monitor weather updates and heed all local advisories.
