About San Marcos weather
San Marcos is in Hays County, Texas, United States at 29.88°, -97.94°. Right now it’s 61° and partly cloudy; today’s high is 69° with a 1% chance of rain.

The state is so large that it spans multiple climate zones, with annual rainfall ranging from over 55 inches in the east to less than 10 inches in far west Texas near El Paso.
