Lake Roosevelt sees dramatic changes in weather throughout the year. In the summer months, temperatures can range from 75ºF to 113ºF during the day, and from 50ºF to 80ºF at night. Spring and fall serve as the transitional periods between hot and cold. Winter sees light to heavy snowfall in all districts and can severly impact roads and access to certain parts of the lake. In addition, the northern reaches of the lake are cooler and wetter, while the southern portion is hotter and drier. The weather combined with lake level changes produces a variety of beautiful landscapes year round.
