Plan for the conditions

Expected seasonal weather

In fall, the Davis Mountains usually bring sunny, mild afternoons and dry air. Nights at the observatory, 6,200–6,800 feet up, are much colder than most of Texas, and wind on the mountain makes them feel colder still. By November, evenings can drop near freezing, and a cold front can make one night far colder than the last. The July–August rainy season is over by fall, so clear skies are more common, but clouds can still cancel telescope viewing. These are seasonal expectations, not a forecast for your travel date; check the NWS forecast the day before and the afternoon of your trip.

Admission and parking are separate. Check current conditions before departure.

A good day, in the bag.
