San Antonio, Texas, is preparing for a major heatwave this week, as temperatures are expected to reach near 98°F by Tuesday afternoon, July 29. The intense heat will be made worse by high humidity, pushing the heat index up to 102°F, making conditions even more dangerous, especially during the afternoon hours.
Dangerous Heat and High Temperatures
According to the National Weather Service, Tuesday will see plenty of sunshine and calm winds, which will combine to create unsafe heat conditions across Bexar County and nearby areas. This will mark the start of the hottest stretch of the week, with daily highs expected to reach 99°F from Wednesday through Saturday.
With the heat at dangerous levels, residents are urged to limit outdoor activities between 1 p.m. and 6 p.m., when the temperatures will be at their peak. Hydration is key, and it’s important to check on vulnerable neighbors, pets, and anyone at risk of heat-related illnesses.
Heat-Related Concerns on the Roads
As the temperature climbs, TXDOT warns that heat-related road issues, like pavement buckling, could become a problem, especially on busy roads such as I-35 and Loop 410. Drivers should take extra caution when traveling during the heat of the day.
Forecast Details
Tuesday’s weather will be hot, with sunny skies and light southeast winds up to 5 mph. Though temperatures will reach 98°F, the humidity will make it feel like 102°F.
By Wednesday, temperatures will rise to 99°F, with little relief at night as lows only dip to about 77°F. Thursday and Friday will follow a similar pattern, with hot days and warm nights under mostly clear skies.
Weekend Outlook
