 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.
