Climate Insight: Santa Ana Fire Stn, CA

The NOAA 1991–2020 climate normals describe Santa Ana Fire Stn, California as a location with an annual average temperature of 66°F, ranging from a mean daily high of 76°F to a mean daily low of 57°F. August is typically the warmest month of the year, while December is the coldest. These thirty-year averages, computed from station USC00047888, 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. Santa Ana Fire Stn receives roughly 12.5 inches of precipitation each year, with seasonal snowfall possible. Growing-season length varies with elevation and microclimate, with the last spring freeze near N/A and the first fall freeze near N/A. For energy use, 927 heating degree days and 1,335 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 Ana Fire Stn 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 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.
