The climate of San Angelo is subtropical, with quite mild winters and very hot, sunny summers.
The city is located in west-central Texas, at 570 meters (1,870 feet) above sea level, and is windy and exposed to clashes between air masses which cause sudden changes in temperature.
In winter, from December to February, the days are quite mild, but at night, the temperature drops a lot.
In addition, every now and then, there may be cold spells and snowfalls. On average, 5.5 cm (2.2 in) of snow fall per year.
