San Antonio Braces for Weekend Heatwave with ‘Feels-Like’ Temperatures Soaring

San Antonio, TX, August 21, 2026 —

San Antonio residents are preparing for a significant heat event this weekend as forecasters predict oppressive conditions with dangerously high “feels-like” temperatures.

The National Weather Service has issued warnings for the metropolitan area, with heat index values, commonly referred to as “feels-like” temperatures, expected to climb as high as 107 degrees Fahrenheit over Saturday and Sunday.

This surge in temperature is attributed to a combination of high ambient heat and humidity, creating a substantial risk of heat-related illnesses for individuals exposed to the elements for extended periods.

Officials are urging the public to take precautions to stay safe during the heatwave. Recommendations include increasing fluid intake, avoiding strenuous outdoor activities during peak heat hours, and seeking out air-conditioned spaces whenever possible. Vulnerable populations, such as the elderly, young children, and those with pre-existing health conditions, are particularly at risk and should exercise extreme caution.

The city’s Office of Emergency Management has not yet announced specific cooling center openings, but residents are advised to stay informed through local news and official city channels for updates on available resources. The prolonged exposure to such high temperatures, even with precautions, poses a serious health threat.
