The year, day by day
Covelo works both ends of the calendar. Normal highs climb to 94°F by July 24 and hold at or above 90°F on 54 dates, then normal lows drop to freezing or below on 17 dates, bottoming at 32°F around December 25.
When the heat sits
Normal highs reach 90°F from July 5 through August 27, covering 54 dates. The broader mild season, normal highs of 70°F or more, runs April 27 to October 25.
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.
The freezing stretch
The normal low stays at or below 32°F into January 4, then returns to freezing around December 19, covering 17 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 December 13, when 44% of years recorded at least a hundredth of an inch. The driest is July 27 at 1%. Summed across the calendar, that is about 87 wet dates a year.
The widest day
September 19 carries the biggest normal gap between afternoon and dawn, 43°F between the normal high and the normal low.

Where Covelo Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 43°F, sharper than nine in ten ranked stations see.

Covelo's wet season runs through the cold months
December, January and February carry 58% of the year's precipitation here, while June through August contribute 2%. 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 a 31.3°F seasonal spread.
- Wettest month
- December, 8.8"
- Driest month
- July, 0.0"
- Wettest three months
- December, January, February (58% 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 Covelo, it arrives in quantity
40.4" of precipitation falls across only about 86 wet days here, averaging 0.47 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 86 a year, 24% of all days
- Average depth per wet day
- 0.47 inches
- Most wet days
- December, about 15
- 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.
Snow reaches Covelo, but rarely amounts to much
The normals record 3.3 inches of snow a year here, most likely in February. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 2 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Covelo's climate pattern fits together
heating led · moderate · mid swing
Covelo's energy balance leans toward cold weather: 3,973 annual heating degree days against 632 for cooling. Its 31.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Covelo's frost-free season lasts about 179 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and December mark the typical warm and cold ends of the calendar in Covelo's middle-range seasonal profile. The measured spread is 31.3°F. The annual average is 56°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Covelo's 40.4 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 3.3 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Covelo'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 Covelo, not an official NOAA class or a year-ahead forecast.
