Climate Rocky Boy Reservation has a wide variation of climate conditions. Near Box Elder, the climate is warmer during the summer months, as a result of the lower elevation, and windier during the cold winter months. During the cold winter months, the Chinook winds can cause damage around the Box Elder region. High wind storms often occur during the winter months. With the warmer temperatures, the Chinook Winds result in melting snow. The Chinook Winds also occur in the Bear Paw Mountains, but their strength there is not as great as on the open plains. The winds may warm the communities located in the Bear Paw Mountains during the winter months. Precipitation, especially in the form of snow, is somewhat higher in the mountains than on the plains.
