When you are on your Glacier National Park vacation, one thing you may encounter is what the locals call "weather". The Rocky Mountains are known for rapidly changing weather conditions, and the peaks of Glacier and valley of the Flathead are no different. If you plan ahead for all conditions, you will get to experience the grandeur of this majestic place in comfort and safety.
Warm summer weather can range from a bright, dry and sunny 80 degrees in mid-day to a clear and cold 45 degrees at night. Spring and Fall can have even more drastic ranges of temperature, with more likelihood of unexpected showers and sudden coolness in the evenings. Pack sun protection, a rain layer and a warm jacket for the evening and you'll be prepared for the extremes.
Winter average temperatures hover around 20 degrees with occasional drops to 10 below zero and colder, and various forms of snow fall frequently. Dress in layers with wool or synthetic materials, avoiding cotton. Wind and waterproof outer layers will greatly improve your comfort zone, and don't forget a warm hat, gloves, neck gator or scarf and snow boots! The warmer and drier you are, the more you'll enjoy the winter wonderland of Glacier National Park!
