Climate - The climate in Montana varies with the terrain. The western region of the state receives storm systems from the Pacific Ocean, which tend to be temperate. Because of its mountainous topography the region receives significant snowfall amounts, with winter temperatures usually below freezing.
Summer in this region is mild with high temperatures reaching 85 degrees F. Nights are cool in the mountains during the summer. Bring warm layers, hats and gloves if camping. High country roads usually do not open until mid to late June, due to snow accumulation. Thunderstorms are a daily occurrence in June, July and August, so be prepared for rain in the mountains.
