*Data for Rapid City was compiled from the office’s three locations: the original downtown Weather Bureau Office (WBO) data goes from 1888-1942; the office moved to the airport in 1942, and relocated to East Rapid City in 1995. Average highs and lows were calculated based on averaging those of the three different sites.
