The morning warmth is already settling over South Texas, and the sun is quickly taking over the skyline. Pavement is heating up, the air feels increasingly humid, and another stretch of midsummer heat is unfolding across the San Antonio metro.
San Antonio, Texas – Temperatures continue climbing through late Monday morning, with afternoon highs expected to reach 96 degrees. According to the National Weather Service in Austin/San Antonio, humidity will push the heat index as high as 101 degrees, making it feel significantly warmer during the afternoon commute and outdoor activities.
Skies become mostly sunny through the day as a light southeast wind turns southerly near 5 mph. Travelers along Interstate 35, Interstate 10, Loop 410, and U.S. Highway 281 should expect intense sunshine and increasing heat during the afternoon. While no widespread hazardous weather is expected today, anyone working outside should schedule frequent breaks, wear lightweight clothing, and stay hydrated.
Tuesday brings another hot day with a high near 96 degrees and heat index values around 100 degrees. The hottest period of the week arrives Wednesday when temperatures climb to 98 degrees under sunny skies. The prolonged stretch of warm afternoons could increase energy demand and place extra stress on those without reliable cooling.
By Thursday, the weather pattern begins to change slightly. A 20 percent chance of showers develops late Thursday night as Gulf moisture slowly returns. Isolated showers and thunderstorms remain possible into Friday, though most of the day will still be warm with highs near 95 degrees.
Across Texas, above-average temperatures continue to dominate much of the region this week beneath a persistent ridge of high pressure. While stronger storm systems remain well north of South Texas, residents should continue monitoring the latest weather updates as rain chances gradually increase late in the week.
