The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 28, short of 90°F on every date, while 198 dates carry a normal low at or below freezing, the coldest 14°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into April 27, then returns to freezing around October 13, covering 198 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 1, when 52% of years recorded at least a hundredth of an inch. The driest is August 7 at 14%. Summed across the calendar, that is about 131 wet dates a year.
The widest day
July 29 carries the biggest normal gap between afternoon and dawn, 36°F between the normal high and the normal low.
Look up any date
Any date's 1991–2020 normal for Cascade.
Where Cascade Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 198 nights a year, placing this among the most frost-prone tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 36°F between the normal high and low.
Cascade earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Cascade'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 11%. 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 42°F seasonal spread.
- Wettest month
- December, 3.5"
- Driest month
- August, 0.4"
- Wettest three months
- December, January, March (38% 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.
Rain reaches Cascade in small, frequent amounts
Cascade records about 132 days with measurable precipitation a year and 23.8" in total, which works out to roughly 0.18 inches on an average wet day. Precipitation on 36% of all days, arriving that lightly, is the damp many-grey-days pattern rather than the storm-driven one.
Places in this band read as wetter than their annual totals suggest, because what people notice is the number of overcast days, not the depth in the gauge.
- Most wet days: December, about 16 of them.
- Fewest: August, about 4.
- Average depth per wet day: 0.18 inches.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Winter brings real snow to Cascade
Cascade averages 86.3 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 45 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 86.3 inches of depth.
- Days recording measurable snow: about 45 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 36% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Cascade
heating led · moderate · mid swing
Cascade's energy balance leans toward cold weather: 8,040 annual heating degree days against 160 for cooling. Its 42.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 112 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
