Why is San Antonio So Hot?

San Antonio is located in South Texas in an area known as the Texas Hill Country. They do not have a coastal climate like Corpus Christi or Houston, but they can get very hot. During the summer, it can seem like an endless heat wave in San Antonio. The Texas Hill Country is considered a semi arid climate area.

As they say in real estate, it is location, location, location, and the wind can dictate these hot temperatures in San Antonio. Being situated near the Gulf of Mexico, wind blowing from the gulf can increase moisture levels, but keep temperatures below 100 degrees.

Since San Antonio is also near the Mexican border, hot air can also blow in from the deserts to the sound around the Rio Grande and Mexico. These winds from the southwest and south increase the temperature and lower the humidity.

According to Texas Monthly, “In Houston, Corpus, San Antonio—just about any place southeast of a line from Dallas to Del Rio—the average desert equivalent temperature in summer is slightly over 100°.”

When in Death Valley, California, the average is 98.6 F., even though Death Valley still holds the record for the hottest temperature recorded in the United States.

With all these hot temperatures, it actually has snowed in San Antonio during the winter, and at times they also get freezing rain with temperatures below freezing, such as the winter of 2017/2018.
