In the summer, daytime temperatures range from 65 F to 85 F degrees with cooler temperatures at night. Occasionally there are brief showers in the afternoons. In the winter, daytime temperatures range from 20 to 55 degrees F., dropping to 15 degrees or less at night.
Most days are sunny, and most of the snow falls at night.
The heat of the mid-afternoon can quickly turn into a cool early evening. Be prepared for these temperature changes by wearing layers of easily removable clothing. So don't forget the sunscreen and sunglasses. Above 5,000 feet, you may experience a faster heartbeat and an increase in your breathing rate due to the lower oxygen levels - all very normal. For the first two or three days, some people may experience dizziness, headaches, nasal congestion, fatigue, nausea and sleeping difficulties.
