Weather in March

March is a cold month that tails the winter season in Montana. Spring sees snowfall in most regions, with the valleys also receiving fair amounts of snow. Locations in the southwest such as Hebgen Lake Dam at 25.2" (640mm) and south-central locations, such as Mystic Lodge with 29.8" (757mm), receive a large amount of snow in March along with the Beartooth Mountains.
Rainfall is in small amounts with the west part of Montana receiving more than the east. Roughly 10 to 12 days experience sunshine in March, and the conditions are windy and cold in most places.
The average high temperatures are in the mild 40°F (4.4°C) to 50°F (10°C) range, while the nights are cold with average low temperatures in the frigid range of 15°F (-9.4°C) to 30°F (-1.1°C).
Though the severe cold of winter subsides by early spring, it is still cold and windy with a little moisture in the air. Therefore, pack in layers for availing early-bird discounts during the spring season as the tourist season still lacks numbers.
