The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around July 29, short of 90°F on every date, while 1 dates carry a normal low at or below freezing, the coldest 32°F near December 27.
The freezing stretch
Freezing normal lows set in around December 27, covering 1 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 November 27, when 64% of years recorded at least a hundredth of an inch. The driest is July 29 at 10%. Summed across the calendar, that is about 159 wet dates a year.
The widest day
August 14 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Cascadia Stands Nationally
This is one of the wettest normals climates ranked: about 63 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Daily temperature swings run wider than most of the country, peaking near 33°F between the normal high and low.
Cascadia earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Cascadia's wet season runs through the cold months
December, January and February carry 38% of the year's precipitation here, while June through August contribute 7%. 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 25.8°F seasonal spread.
- Wettest month
- December, 9.6"
- Driest month
- July, 0.6"
- Wettest three months
- December, November, January (42% 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 Cascadia, it arrives in quantity
63.1" of precipitation falls across only about 159 wet days here, averaging 0.40 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 159 a year, 43% of all days
- Average depth per wet day
- 0.40 inches
- Most wet days
- December, about 19
- Fewest wet days
- July, about 4
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 Cascadia's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Cascadia, at 5,540 degree days versus 118 for cooling. Unlike a strongly continental record, however, its 25.8°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Cascadia's frost-free season lasts about 167 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Cascadia's 25.8°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 50°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Alongside its heating load, Cascadia carries 63.1 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 Cascadia'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 Cascadia, not an official NOAA class or a year-ahead forecast.
