San Antonio, TX – Dangerous heat will grip South Central Texas on Thursday as temperatures climb near 99°F, pushing heat index values up to 102°F. The hottest conditions are expected between 2 and 6 p.m., raising risks for heat exhaustion during outdoor activities.
According to the National Weather Service, a strong ridge of high pressure will keep skies mostly sunny, with only light south-southeast winds at 5 to 10 mph offering minimal relief. Communities across Bexar County, including Alamo Heights and Converse, should take precautions by limiting strenuous outdoor work and staying hydrated. City services are reminding residents that cooling centers will be available during peak afternoon hours.
Friday will remain hot, topping out near 98°F, before a slight chance of showers and thunderstorms returns Saturday afternoon. While the rain may offer some relief, humidity will keep the heat index elevated.
The prolonged heat stretch could lead to higher electricity demand as residents run air conditioning. Officials recommend checking on elderly neighbors, keeping pets indoors, and avoiding car travel with children or animals during the afternoon peak. Heat advisories may be extended if temperatures remain above normal through Sunday.
