San Antonio, Texas – San Antonio is bracing for another surge of extreme summer heat, with temperatures climbing to near 99°F by Thursday and heat index values topping 102°F, creating dangerous conditions for anyone outdoors. Relief remains elusive as overnight lows barely dip below the upper 70s, providing little chance for the city to cool down.
According to the National Weather Service in San Antonio, the worst of the heat will grip the region through Thursday, with high pressure keeping skies clear and driving humidity up. Highs are expected to reach 98°F to 99°F through Saturday, while “feels-like” temperatures could push past 100°F each afternoon. Winds will be light and southeast, offering little comfort from the sweltering sun.
Residents in downtown San Antonio and surrounding communities, including Helotes and Leon Valley, should avoid strenuous activity outside during peak afternoon hours. City officials urge everyone to check on elderly neighbors, stay hydrated, and keep pets indoors as the heat wave lingers. With little overnight cooling, power grids may also face extra strain as air conditioners run continuously.
Hot, sunny weather continues through the weekend, with only minor breezes and no significant rain in sight. Authorities warn the heat threat will persist into early next week, and more advisories may follow if conditions intensify.
