NOAA publishes no 1991-2020 snowfall normal for this station, and no record within 25 miles keeps one, so snow is left out here rather than estimated.

When is the best weather to visit Beulah?

Normal highs sit between 65°F and 85°F in May, June and September. Of those, September has the fewest days with rain (4).

That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

The USDA's 2023 Plant Hardiness Zone Map puts Beulah in zone 4a in ZIP code 58523, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, Beulah's NOAA station is in zone 3b: the coldest night of a typical year reaches −31°F (16 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.

Which places near Beulah share this climate record?

3 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
