On the calendar, San Antonio is moving past the peak of its summer heat. Still, the next several days will feel much the same. Really hot.<\/p>\n
National Weather Service climate records<\/a> show Aug. 1-14 is historically the city\u2019s warmest stretch, with an average high of 97 degrees. That number begins to inch downward by mid-August, dipping to 96 degrees by Aug. 17 and 95 degrees by Aug. 23.<\/p>\n \u201cThat drop typically happens when the areas of high pressure over the southern United States begin to weaken or shift,\u201d said Eric Platt, a meteorologist at the National Weather Service\u2019s Austin-San Antonio office. \u201cTemperatures can still be quite warm, but we tend to see a more noticeable drop in October.\u201d<\/p>\n This year, that transition may arrive later than usual. Highs are forecasted<\/a> to range from 97 degrees to 100 degrees over the next week, with morning lows in the mid to upper 70s. Seasonal outlooks from the Climate Prediction Center<\/a> tilt toward above-normal temperatures and near-normal rainfall from September through November.<\/p>\n \u201cThat could mean the heat lingers a little longer than average this year,\u201d Platt said.<\/p>\n The summer heat fits a broader trend: The National Oceanic and Atmospheric Association ranked July 2025 as the third hottest July globally<\/a> since records began in 1850. Texas saw one of its warmest thirds of Julys<\/a> on record, and the Southern Region of the United States experienced significantly warmer-than-average overnight temperatures.<\/p>\n For residents hoping for relief, history offers some guidance. San Antonio\u2019s average high doesn\u2019t fall below 90 degrees until around Sept. 19<\/a>, and overnight lows often stay in the 70s well into early fall.<\/p>\n
