The year, day by day
The calendar barely moves in Mt Laguna: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 33°F near January 25 and 83°F near July 12.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 33°F around January 25.
The widest day
June 14 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Monthly Precipitation
Average monthly rainfall
Mt Laguna's wet season runs through the cold months
December, January and February carry 56% of the year's precipitation here, while June through August contribute 7%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows an unusually narrow 29.5°F seasonal spread.
- Wettest month
- February, 4.8"
- Driest month
- June, 0.1"
- Wettest three months
- February, January, March (57% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.

Data-derived climate profile
How Mt Laguna's climate pattern fits together
heating led · dry · low swing
Heating is the larger measured load in Mt Laguna, at 4,361 degree days versus 537 for cooling. Unlike a strongly continental record, however, its 29.5°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Mt Laguna's frost-free season lasts about 200 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
The calendar stays thermally compact and dry. July and January mark the typical warm and cold ends of the calendar, only 29.5°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 54°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Mt Laguna's cold-season load does not imply a wet climate. Annual precipitation is 17.6 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Mt Laguna's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Mt Laguna, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Mt Laguna's primary station: MT LAGUNA #3 (USC00045968). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Mt Laguna; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Mt Laguna comes from its primary NOAA station record.
