The Weather at the Observatory

Temperatures vary quite a bit at our elevation (6,300-6,800 feet above sea level) and are usually much cooler than other areas of Texas. For summer make sure you bring a light jacket and long pants. For Fall, Winter, and early Spring programs, layer your attire and bring a warm coat, thermals, gloves, and something to keep your head warm.
