Climate Insight: Bowman Dam, CA
An annual average temperature of 50°F, ranging from a mean daily high of 62°F to a mean daily low of 39°F is what the NOAA 1991–2020 climate normals report for Bowman Dam, California. July is typically the warmest month of the year, while December is the coldest. That baseline comes from station USC00041018 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Bowman Dam receives roughly an uncharted amount of precipitation each year, predominantly as rainfall. The frost-free season averages 170 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 12 and the first fall freeze near October 29. For energy use, 5,655 heating degree days and 343 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Bowman Dam scores 49/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Shoulder seasons bring the mildest highs and lows in the monthly tables above, summer brings July-driven heat, and winter brings December-driven cold - use that rhythm for planning. These figures are thirty-year averages rather than forecasts, so a specific year may still run warmer, cooler, wetter, or drier than what's shown.
