They say if you don't like the weather in Texas, wait a couple hours. That is definitely true of San Angelo, where it can snow one weekend and be sunny and 70 the rest of the week. In West Texas, the wind is almost always blowing, regardless of whatever else the weather is doing. A normal day has a wind speed of 8–12 mph, and on windy days, it will be 15–30 mph. Summers are hot, typically 85–105 degrees. Those spending a lot of time outside during the summer months should take care to stay hydrated. The summer weather generally continues through September, slowly fading into the warm fall weather. Fall is typically a warm and windy 65–85 degree high temperature spread.
During the fall, it will rain occasionally, especially if hurricane remnants make it as far inland as San Angelo. When it rains, the campus and city of San Angelo flood a little. Winter hits in late November or early December, but winters in San Angelo are mild, rarely getting down past 10 degrees. The main concern in winter is the wind-chill factor, where the temperature gauge reads 30F, but you walk outside, and it feels like 15F because of a 30-mph wind. It snows occasionally in San Angelo, but usually not much. Due to a lack of experience driving on icy roads, when the roads ice over, ASU typically delays or cancels class for road safety. Spring temperatures break up the winter weather starting in late January, but winter doesn't totally release its hold until March. Spring temperatures are much like fall, but spring is typically windier than any other season. Watch out for the occasional dust storm behind high winds.
