FALL (SEPTEMBER – NOVEMBER)

Fall

Beautiful days with comfortable, warm weather through September and crisp cool nights into November make fall an excellent time to explore Rapid City and the Black Hills. Temperatures start to cool around Labor Day with highs averaging in the 60s and 70s during the day and dropping into the 40s in the evenings.

WINTER (DECEMBER – MARCH)

Winter

While temperatures may be wintry, cold spells usually alternate with milder weather. The average daytime temperature is in the mid 30s. However, Rapid City’s location at the foot of the Black Hills can be a benefit; occasionally an air inversion will trap warm air over the city, providing unseasonably warm temperatures. Snowfall doesn’t stick around long in the city and usually melts within a few days. The Northern Black Hills usually has an abundance of snow which provides excellent conditions for winter sports.
