The year, day by day
Summer here tops out rather than builds: the warmest normal high is 90°F around July 28, short of 90°F on every date, while 180 dates carry a normal low at or below freezing, the coldest 19°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into April 16, then returns to freezing around October 20, covering 180 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 November 29, when 47% of years recorded at least a hundredth of an inch. The driest is August 5 at 8%. Summed across the calendar, that is about 99 wet dates a year.
The widest day
July 28 carries the biggest normal gap between afternoon and dawn, 37°F between the normal high and the normal low.

Where Leavenworth Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 37°F, sharper than nine in ten ranked stations see.
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 180 nights a year, more than most ranked stations.
Leavenworth earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Leavenworth's wet season runs through the cold months
December, January and February carry 45% 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 a 42.6°F seasonal spread.
- Wettest month
- December, 4.5"
- Driest month
- August, 0.4"
- Wettest three months
- December, January, November (50% 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.
How Leavenworth's precipitation splits across the calendar
About 99 days a year record measurable precipitation here, carrying 25.7" between them, or roughly 0.26 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
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 Leavenworth
Leavenworth averages 80.2 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 29 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: 80.2 inches of depth.
- Days recording measurable snow: about 29 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 31% 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 Leavenworth
heating led · moderate · mid swing
Leavenworth's energy balance leans toward cold weather: 6,806 annual heating degree days against 381 for cooling. Its 42.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 143 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.
-
1. Leavenworth coldest normal
