Climate Insight: Palomar Mtn Obsy, CA
The NOAA 1991–2020 climate normals describe Palomar Mtn Obsy, California as a location with an annual average temperature of 57°F, ranging from a mean daily high of 66°F to a mean daily low of 48°F. August is typically the warmest month of the year, while February is the coldest. These thirty-year averages, computed from station USC00046657, 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. Palomar Mtn Obsy receives roughly 30.4 inches of precipitation each year, with 26.2 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near April 29 and the first fall freeze near November 18. For energy use, 3,835 heating degree days and 981 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Palomar Mtn Obsy scores 72/100 (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 February-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.
