The frost-free season averages 351 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near January 10 and the first fall freeze near December 27. And on the energy front, 643 heating degree days and 4,194 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Santa Rosa scores 100/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above turn that into a planning tool: expect the mildest highs and lows in the shoulder seasons, August-driven heat at the peak of summer, and January-driven cold at the depth of winter. Every number here is a thirty-year average, not a forecast, so any given year can and does run warmer, cooler, wetter, or drier than the normal.
