The year, day by day
The year in Cloverdale runs from a mild 37°F around December 21 to 95°F at the peak near July 14, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 18 through September 16, covering 91 dates. The broader mild season, normal highs of 70°F or more, runs March 30 to November 8.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
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 37°F around December 21.
Where the wet dates fall
The likeliest wet date is January 7, when 41% of years recorded at least a hundredth of an inch. The driest is July 23 at 1%. Summed across the calendar, that is about 73 wet dates a year.
The widest day
July 20 carries the biggest normal gap between afternoon and dawn, 40°F between the normal high and the normal low.

Where Cloverdale 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.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 91 days a year, more than four out of five ranked stations record.
Cloverdale earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Cloverdale's wet season runs through the cold months
December, January and February carry 60% 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 26.6°F seasonal spread.
- Wettest month
- December, 8.8"
- Driest month
- July, 0.0"
- Wettest three months
- December, January, February (60% 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 Cloverdale, it arrives in quantity
41.7" of precipitation falls across only about 73 wet days here, averaging 0.57 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 73 a year, 20% of all days
- Average depth per wet day
- 0.57 inches
- Most wet days
- January, about 13
- Fewest wet days
- July, 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.
Cloverdale's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile
How Cloverdale's climate pattern fits together
mixed demand · moderate · low swing
Temperature varies within a narrow 26.6°F band across the normal year. July and December mark the typical warm and cold ends of the calendar. The annual average is 62°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
Cloverdale combines a compact 26.6°F annual temperature range with meaningful demand on both sides of the thermostat: 2,378 heating and 1,210 cooling degree days. The balance matters more here than either annual total in isolation.
The frost-free window extends for about 281 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
Cloverdale's 41.7 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Recorded annual snowfall is negligible. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Cloverdale's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Cloverdale, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
