San Antonio is heading into another brutally hot afternoon, with mostly cloudy skies early Thursday giving way to sunshine and a high near 99 degrees. The heat index could reach 106, making the day feel significantly hotter than the thermometer suggests.
Heat Peaks Thursday Afternoon
The National Weather Service forecast calls for mostly sunny skies, south-southeast winds of 5 to 10 mph and only a 2% chance of rain. Temperatures are expected to climb through the 90s before reaching their peak late in the afternoon, when outdoor plans will be most taxing.
Thursday night should turn mostly clear, with a low around 77 and southeast winds of 5 to 10 mph, including gusts as high as 20 mph. The forecast calls for only a slight chance of rain, and the National Weather Service has no active watches, warnings or advisories for the San Antonio area. The National Weather Service says most of South-Central Texas will remain hot and dry.
Little Relief Through Next Week
Friday and Saturday will bring mostly sunny skies and highs near 97, followed by another 97-degree day Sunday and Monday. Rain chances remain low, with any better opportunity for showers or thunderstorms mainly confined to the Coastal Plains.
The heat returns to the upper 90s Tuesday and Wednesday, when highs are forecast to reach 99 under sunny or mostly sunny skies. Overnight lows will stay in the upper 70s, offering some relief but not exactly a deep freeze.
Heat Safety Remains Important
Even without an advisory, a heat index near 106 is enough to make prolonged outdoor activity risky. San Antonio officials recommend staying hydrated, taking breaks in air conditioning and checking on older adults, young children, people with medical conditions and pets; the City’s hot-weather guidance also points residents toward local heat-relief resources.
