Montague has a Mediterranean climate closely bordering on a steppe climate, very unusual for its location west of the Cascade Crest. Montague and the Shasta Valley are located in a rain shadow created by the Klamath Mountains, giving the area a climate and vegetation type more similar to points east of the Cascades, with average annual precipitation similar to Bend, Oregon. Rainfall is nonexistent in summer, except for the very occasional thunderstorm. The area experiences cool to cold winters with somewhat frequent snowfall, and hot summers with large diurnal temperature variation and nearly constant sunshine.
