Climate Insight: Santa Monica Muni, CA
The NOAA 1991–2020 climate normals describe Santa Monica Muni, California as a location with an annual average temperature of 63°F, ranging from a mean daily high of 70°F to a mean daily low of 55°F. August is typically the warmest month of the year, while December is the coldest. These thirty-year averages, computed from station USW00093197, 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 Monica Muni receives roughly 13.4 inches of precipitation each year, predominantly as rainfall. 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, 1,388 heating degree days and 613 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 Monica Muni 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.
