Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Richland sees about an uncharted amount of precipitation a year, predominantly as rainfall. The frost-free season averages 144 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 10 and the first fall freeze near October 1. On the energy side, 6,231 heating degree days and 597 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Richland scores 49/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above are the practical planning tool: mild highs and lows land in the shoulder seasons, July-driven heat peaks in summer, and January-driven cold sets in over deep winter. These are thirty-year averages, not a forecast - any single year can run warmer, wetter, drier, or cooler than the normal.
