Hottest May in San Antonio recorded in 2022
according to National Weather Service.

It was the hottest May on record according to the National Weather Service in San Antonio / New Braunfels. It’s astonishing to say that with records going back all the way to spring of 1885. There’s a couple of days when the Alamo City had reached triple digits. The factors that came about this record are the average lows and highs which came to be 82.2 degrees fahrenheit beating the previous contender of May in 1996, which that recorded as an average of 81.9 degrees fahrenheit. You’re gonna wanna wipe the sweat off your face when you hear that we had hit a high temperature of 101 a whopping four times already in the month of May. Those dates were on 5/7, Mother’s Day (5/8), 5/18 & 5/21. Also, it appears that the end of May won’t result in any participation from the skies above that are desperately needed. We’re not even in summer yet, which starts on June 21st.
