Climate Insight: Henshaw Dam, CA

The NOAA 1991–2020 climate normals describe Henshaw Dam, California as a location with an annual average temperature of 58°F, ranging from a mean daily high of 75°F to a mean daily low of 40°F. August is typically the warmest month of the year, while December is the coldest. These thirty-year averages, computed from station USC00043914, 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. Henshaw Dam receives roughly 25.2 inches of precipitation each year, predominantly as rainfall. Growing-season length varies with elevation and microclimate, with the last spring freeze near April 18 and the first fall freeze near October 26. For energy use, 3,477 heating degree days and 780 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Henshaw Dam scores 77/100 (Good), 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 August-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.
