Climate Insight: Auburn, CA
An annual average temperature of 61°F, ranging from a mean daily high of 73°F to a mean daily low of 49°F is what the NOAA 1991–2020 climate normals report for Auburn, California. July is typically the warmest month of the year, while December is the coldest. That baseline comes from station USC00040383 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Auburn sees about 36.1 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 283 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near February 25 and the first fall freeze near December 5. On the energy side, 2,813 heating degree days and 1,453 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Auburn scores 92/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows, shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for December-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
