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.
The eastern plains of Montana generally experience more dramatic weather patterns than the west. Summer temperatures reach 100 degrees F in many areas. May and June are normally the rainy months of the year, but summer brings thunderstorms almost daily. Winter weather is also extreme in this region. Cold winds blow from the north creating a severe wind-chill factor. Snow usually doesn't accumulate on the prairies, because most of the moisture is absorbed by the western mountains.
