The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 31, short of 90°F on every date, while 111 dates carry a normal low at or below freezing, the coldest 30°F near December 16.
The freezing stretch
The normal low stays at or below 32°F into March 16, then returns to freezing around November 27, covering 111 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
Where the wet dates fall
The likeliest wet date is February 20, when 27% of years recorded at least a hundredth of an inch. The driest is June 15 at 2%. Summed across the calendar, that is about 47 wet dates a year.
The widest day
June 13 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Idyllwild Fire Dept'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 5%. 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 28.4°F seasonal spread.
- Wettest month
- February, 5.3"
- Driest month
- June, 0.1"
- Wettest three months
- February, January, December (56% 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.
When it rains in Idyllwild Fire Dept, it arrives in quantity
24.5" of precipitation falls across only about 47 wet days here, averaging 0.52 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 47 a year, 13% of all days
- Average depth per wet day
- 0.52 inches
- Most wet days
- February, about 8
- Fewest wet days
- June, about 0
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.
Winter brings real snow to Idyllwild Fire Dept
Idyllwild Fire Dept averages 30.7 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 11 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 30.7 inches of depth.
- Days recording measurable snow: about 11 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 13% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Idyllwild Fire Dept
heating led · moderate · low swing
Heating is the larger measured load in Idyllwild Fire Dept, at 4,321 degree days versus 525 for cooling. Unlike a strongly continental record, however, its 28.4°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Idyllwild Fire Dept's frost-free season lasts about 161 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Idyllwild Fire Dept's primary station: IDYLLWILD FIRE DEPT (USC00044211). 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 Idyllwild Fire Dept; 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 Idyllwild Fire Dept comes from its primary NOAA station record.
