Climate Insight: Santa Ana Fire Stn, CA
Based on station USC00047888 feeding NOAA's 1991–2020 climate normals, Santa Ana Fire Stn, California averages 66°F a year, 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.

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 negligible snowfall. Growing-season length varies with elevation and microclimate. 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. Shoulder seasons bring the mildest highs and lows in the monthly tables above, summer brings August-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.
