The Maloja Wind (German: Malojawind) is a Foehn-type mountain wind that occurs in the upper Engadin, an alpine valley located in Switzerland. The wind blows up-valley during the nighttime and down-valley during the day, a deviation of the typical direction of mountain and valley winds. The phenomenon is caused by wind from the Val Bregaglia crossing the Maloja Pass and intruding into the Engadin. The Maloja Wind occasionally produces a weather phenomenon known as the Maloja Snake (German: Malojaschlange), a low-lying cloud so named for its long, serpentine shape.
