So far this year, there have been 359 heat-related illnesses in San Antonio. Last year at this time, there had been 316 heat-related illnesses.

There were a total of 504 heat-related incidents for all of 2022.

One death since 2018 has been contributed to heat, and that happened in the week ending on July 17, 2022.

City and county officials are urging people to find a place to keep cool during the extreme heat.

As we’ve entered the middle of summer, afternoon humidity has started to come down as soils have dried out. So, even though it will still be hot outside, the heat index will not be as much of a factor.

People should still exercise heat caution, though, as temperatures will be above 100 degrees. Click here for the latest weather forecast from the KSAT Weather Authority team.
