Due to its location along the east-facing foothills of the Wet Mountains, Beulah is prone to significant orographic enhancement of precipitation in the form of heavy cold-season snowfall as well as significant rain in warm months mostly (in the latter case) due to effects of the North American Monsoon. Per the Köppen climate classification, Beulah has a humid continental climate ("Dfb") but closely borders on up to four other subcategories depending on temperature and precipitation patterns. The average temperature in July is 71.0 °F (21.7 °C), putting it just below the 22 °C threshold for a "Dfa" designation. December and January average just below freezing (31.4 °F); by many American interpretations of the Köppen climate system this makes it just barely too cold to qualify as a "Cfa" or "Cfb" humid subtropical or subtropical highland climate, though such climates do exist especially to the immediate south and southeast in areas including the neighboring towns at similar elevations of Rye and Colorado City. Per the Trewartha climate classification system, Beulah clearly falls into class D ("Dcb" or "Dcbo") as only five months of the year have a mean temperature above 10 °C and like Köppen is too wet to be classified as semi-arid or steppe (Köppen "BSk") found over the vast majority of eastern Colorado and the High Plains.
