The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 22, short of 90°F on every date, while 17 dates carry a normal low at or below freezing, the coldest 32°F near December 20.
The freezing stretch
Freezing normal lows set in around December 15, covering 17 dates.
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 January 9, when 50% of years recorded at least a hundredth of an inch. The driest is July 27 at 1%. Summed across the calendar, that is about 96 wet dates a year.
The widest day
September 22 carries the biggest normal gap between afternoon and dawn, 40°F between the normal high and the normal low.

Where Willits Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 40°F, sharper than nine in ten ranked stations see.

Willits'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 1%. 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 23.2°F seasonal spread.
- Wettest month
- December, 9.8"
- Driest month
- July, 0.0"
- Wettest three months
- December, January, February (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 Willits, it arrives in quantity
49.2" of precipitation falls across only about 95 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 95 a year, 26% of all days
- Average depth per wet day
- 0.52 inches

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.

Data-derived climate profile
How Willits's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Willits, at 4,527 degree days versus 195 for cooling. Unlike a strongly continental record, however, its 23.2°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Willits's frost-free season lasts about 157 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Willits's 23.2°F seasonal spread is compact even though precipitation is abundant. July and December mark the typical warm and cold ends of the calendar. The annual average is 53°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Alongside its heating load, Willits carries 49.2 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Willits'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 Willits, not an official NOAA class or a year-ahead forecast.
