San Antonio is facing dangerously hot conditions this weekend, with triple-digit heat index values and hazy skies making for a potentially hazardous Saturday. According to the National Weather Service (NWS), heat indices are expected to soar up to 102°F by mid-afternoon, raising concerns for outdoor workers, travelers, and anyone planning to be outside for long periods. This heat wave is expected to affect much of south-central Texas, including major roadways like I-35 and Loop 410, where high temperatures could create uncomfortable and unsafe conditions.
On Saturday, the high will reach around 96°F under mostly sunny skies, with light southeast winds blowing at 5 to 10 mph. While the winds may offer a bit of relief, the heat will be intense, especially during peak hours from 2 to 5 p.m. The NWS is urging residents to limit outdoor activities during these hours, stay hydrated, and ensure that vulnerable individuals—such as the elderly, children, and those with medical conditions—are checked on regularly.
The weather conditions will worsen on Sunday as hazy skies become more widespread. This haze could reduce visibility, which may complicate travel plans for early July, especially for drivers and travelers along highways. High temperatures will drop slightly to 93°F, but the haze will persist, making it feel even hotter than the actual temperature. While outdoor activities may seem tempting, it’s important to take precautions to avoid heat exhaustion or heat stroke.
Looking ahead to Monday and Tuesday, the weather will remain hot, with temperatures climbing back up to around 96–98°F. The haze will continue to affect air quality, and there’s also a chance of afternoon thunderstorms on Tuesday, which could provide some relief from the heat but might bring localized flooding in some areas. Residents should remain prepared for sudden changes in weather and keep an eye on any weather alerts issued by the NWS.
The latter part of the week, particularly on Wednesday and Thursday (July 2–3), will see isolated storms in the forecast, but highs will still hover near 97°F. While the storms may help cool things down a little, the overall pattern of hot, hazy weather will continue, making it important to plan any outdoor activities carefully and take the necessary precautions against heat-related illnesses.
For those in San Antonio and the surrounding areas, here is the updated five-day weather forecast:
Friday, June 28: Mostly sunny, with a high of 94°F.
Saturday, June 29: Mostly sunny, high of 96°F with heat index reaching 102°F.
Sunday, June 30: Partly sunny and hazy, high of 93°F.
Monday, July 1: Hazy skies with temperatures rising to 96°F.
Tuesday, July 2: Hazy conditions with a chance of storms, high of 98°F.
As we approach the weekend, it’s essential to stay aware of the heat, especially if you’re planning any outdoor activities. Remember to protect yourself from the heat, stay hydrated, and avoid prolonged exposure to direct sunlight during the hottest parts of the day. If you have travel plans, be mindful of the haze and reduced visibility, and take extra care when driving.
Stay informed and prepared, and be sure to follow safety guidelines to protect yourself and your family from the extreme heat expected in San Antonio.
