Santa Monica Muni, California runs an annual average of 63°F, ranging from a mean daily high of 70°F to a mean daily low of 55°F, per NOAA's 1991–2020 climate normals. August is typically the warmest month of the year, while December is the coldest. Drawn from station USW00093197, these thirty-year averages smooth out year-to-year swings into a baseline for what a typical month looks like here.
Anyone planning to live, garden, or travel in Santa Monica Muni should weigh precipitation alongside temperature: the annual average runs 13.4 inches, predominantly as rainfall. Growing-season length varies with elevation and microclimate. And on the energy front, 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.
