🌡 The weather here, in general

Rapid City gets a real winter. February nights average 17°F, and July highs reach about 86°F — a 69-degree swing across the year. Cold that deep is its own hazard: exposed skin, car batteries and water pipes all have opinions about it.

The thermometer rarely spikes — only about 21 days a year top 90°F — but it hardly needs to. Summer sits in the mid-eighties for months at a stretch, and with humidity on top of it the heat index runs well above what the air temperature suggests.

Snow is a real feature of the year: roughly 37 inches falls in an average year, mostly across February, March, April, October and December. With 144 nights a year at or below freezing, ice on the roads is a longer season than snow on the ground.

Rainfall averages about 18 inches a year, wettest in May and driest in January.
