San Antonio is hot in the summer. That\u2019s a given, and a part of living in South Central Texas. <\/p>\n
During a stretch of seemingly never-ending triple-digit days, you might be wondering, \u201cWhat\u2019s the hottest it\u2019s ever been in the Alamo City?\u201d<\/p>\n

San Antonio\u2019s hottest temperature<\/p>\n
On Sept. 5, 2000, the temperature reached a whopping 111\u00b0 at San Antonio International Airport \u2014 the official weather site. This is the highest temperature ever in San Antonio\u2019s weather record, which dates back to 1885.<\/p>\n
Here\u2019s a look at the 10 hottest recorded days in the Alamo City:<\/p>\n

These numbers may come as a surprise. Perhaps, the temperatures are not as high as you might think. <\/p>\n
The reason San Antonio very rarely sees a temperature above 110\u00b0 is because of our high humidity and proximity to the Gulf. The air doesn\u2019t warm up very easily when more water present.<\/p>\n
Places with less humidity, like the Desert Southwest, the Great Plains, or valleys in the Pacific Northwest will occasionally record highs equal to or even hotter than San Antonio\u2019s record of 111\u00b0. <\/p>\n
In 2021, Portland, Oregon saw 116\u00b0. Redding, California recorded 119\u00b0 in 2024. During the Dust Bowl of 1936, Fargo, North Dakota experienced 114\u00b0.<\/p>\n
