The year, day by day
Cave Junction works both ends of the calendar. Normal highs climb to 96°F by July 26 and hold at or above 90°F on 66 dates, then normal lows drop to freezing or below on 13 dates, bottoming at 32°F around December 25.
When the heat sits
Normal highs reach 90°F from July 2 through September 5, covering 66 dates. The broader mild season, normal highs of 70°F or more, runs April 27 to October 19.
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 3, then returns to freezing around December 22, covering 13 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 10, when 59% of years recorded at least a hundredth of an inch. The driest is July 31 at 4%. Summed across the calendar, that is about 119 wet dates a year.
The widest day
August 13 carries the biggest normal gap between afternoon and dawn, 45°F between the normal high and the normal low.

Where Cave Junction Stands Nationally
This is one of the wettest normals climates ranked: about 61 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 45°F, sharper than nine in ten ranked stations see.
Cave Junction earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Cave Junction's wet season runs through the cold months
December, January and February carry 54% 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 33.2°F seasonal spread.
- Wettest month
- December, 12.9"
- Driest month
- July, 0.3"
- Wettest three months
- December, January, March (54% 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 Cave Junction, it arrives in quantity
61.2" of precipitation falls across only about 119 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 119 a year, 32% of all days
- Average depth per wet day
- 0.52 inches
- Most wet days
- December, about 19
- Fewest wet days
- July, about 1
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 Cave Junction, but rarely amounts to much
The normals record 7.1 inches of snow a year here, most likely in January. 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 3 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 Cave Junction's climate pattern fits together
heating led · wet · mid swing
Cave Junction's energy balance leans toward cold weather: 4,323 annual heating degree days against 656 for cooling. Its 33.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Cave Junction's frost-free season lasts about 164 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 Cave Junction's middle-range seasonal profile. The measured spread is 33.2°F. The annual average is 55°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Cave Junction carries 61.2 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 7.1 inches. 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 Cave Junction'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 Cave Junction, not an official NOAA class or a year-ahead forecast.
