Climate Insight: MT Laguna #3, CA

The NOAA 1991–2020 climate normals describe MT Laguna #3, California as a location with an annual average temperature of 54°F, ranging from a mean daily high of 65°F to a mean daily low of 44°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00045968, 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. MT Laguna #3 receives roughly 17.6 inches of precipitation each year, predominantly as rainfall. Growing-season length varies with elevation and microclimate, with the last spring freeze near April 22 and the first fall freeze near November 8. For energy use, 4,361 heating degree days and 537 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, MT Laguna #3 scores 57/100 (Moderate), 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 July-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.
