Climate Insight: Pacifica, CA
An annual average temperature of 57°F, ranging from a mean daily high of 65°F to a mean daily low of 49°F is what the NOAA 1991–2020 climate normals report for Pacifica, California. September is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00046599 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Pacifica receives roughly 31.9 inches of precipitation each year, with negligible snowfall. The frost-free season averages -1 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near January 11 and the first fall freeze near January 10. For energy use, 2,891 heating degree days and 120 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Pacifica scores 79/100 (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 September-driven heat, or deep winter for January-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.
