San Antonio is starting Friday near 80 degrees with sticky air, but the real heat is still loading in. Temperatures are expected to climb to about 98 degrees this afternoon, with the heat index reaching as high as 105. Mostly sunny skies and only a slight chance of rain will set the tone for a long, hot stretch.
Afternoon Heat Builds Quickly
The National Weather Service Austin/San Antonio forecast calls for temperatures to reach the upper 90s by midafternoon, with south-southeast winds of 5 to 15 mph and gusts up to 25 mph. A small 13% rain chance is possible, but most of the city should stay dry. Outdoor plans will be more manageable earlier in the day, before the hottest hours arrive.
Friday night will bring partly cloudy skies and a low around 79, though the heat index could remain as high as 102 during the evening. No watches, warnings or advisories are currently listed for the San Antonio area. The National Weather Service is urging residents to practice heat safety and stay hydrated.
Weekend Heat Turns Even More Persistent
Saturday is forecast to reach 99 degrees with a heat index near 106, followed by another 99-degree day Sunday. Monday and Tuesday should remain sunny and near 99, with rain chances falling to nearly zero. By Wednesday, the high could reach 101 before Thursday settles near 100.
Overnight lows will mostly stay in the mid to upper 70s, offering limited relief after sunset. The combination of repeated triple-digit-feeling afternoons and warm nights can make it harder for people, pets and homes to cool down. Check on older adults, young children and neighbors without reliable air conditioning.
Cooling Options Are Available Around The City
San Antonio officials recommend spending time in air-conditioned spaces, taking frequent water breaks and shifting strenuous outdoor work to the morning or evening. Residents can use the city’s hot weather resources to find cooling information and can call 311 for help locating nearby options. Pets also need shade, fresh water and protection from scorching pavement.
