Average Monthly Temperatures and Precipitation

Hikers should always be prepared for a wide range of temperatures and weather conditions while hiking in Glacier National Park. Temperatures in the mountains typically fluctuate as weather patterns change, especially at the higher elevations.

Glacier's western valleys generally receive the most rainfall. Strong winds and sunny days predominate on the east side of the park. During the summer months, daytime temperatures can exceed 90 degrees; however, overnight lows throughout the park can drop to near 20 degrees, and snow can fall anytime. You should also expect temperatures to be at least 10 to 15 degrees cooler in the higher elevations at any given time.
