Climate Insight: Big Bar, CA
The NOAA 1991–2020 climate normals describe Big Bar, California as a location with an annual average temperature of 57°F, ranging from a mean daily high of 72°F to a mean daily low of 42°F. July is typically the warmest month of the year, while December is the coldest. These thirty-year averages, computed from station USC00040738, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Big Bar receives roughly 35.8 inches of precipitation each year, with 2.7 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near April 16 and the first fall freeze near October 31. For energy use, 3,868 heating degree days and 888 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Big Bar scores 82/100 (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.
