The year, day by day
Washington works both ends of the calendar. Normal highs climb to 91°F by July 16 and hold at or above 90°F on 26 dates, then normal lows drop to freezing or below on 142 dates, bottoming at 15°F around January 17.
When the heat sits
Normal highs reach 90°F from July 7 through August 1, covering 26 dates. The broader mild season, normal highs of 70°F or more, runs May 3 to October 11.
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 March 26, then returns to freezing around November 6, covering 142 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 May 10, when 35% of years recorded at least a hundredth of an inch. The driest is January 18 at 15%. Summed across the calendar, that is about 86 wet dates a year.
The widest day
March 27 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Washington runs a summer-peaked wet season
41% of Washington's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is June at 4.7", on a wide 52.7°F gap between its warmest and coldest month. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: June, May, August, taking 41% of the annual total between them.
- Driest month: January at 0.8".
- Winter share: 10% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
When it rains in Washington, it arrives in quantity
32.4" of precipitation falls across only about 86 wet days here, averaging 0.38 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 86 a year, 23% of all days
- Average depth per wet day
- 0.38 inches
- Most wet days
- May, about 11
- Fewest wet days
- December, about 5
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.
Winter brings real snow to Washington
Washington averages 14.4 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 10 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: 14.4 inches of depth.
- Days recording measurable snow: about 10 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 4% 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 Washington
heating led · moderate · mid swing
Washington's energy balance leans toward cold weather: 5,704 annual heating degree days against 1,314 for cooling. Its 52.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Washington's frost-free season lasts about 173 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
-
1. Washington coldest normal
January
The monthly mean of 26°F (-3°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.
-
2. Washington typical freeze period
January through December
The station reports average freezing days from January through December.
-
3. Washington snow peak
January
Washington averages 14.4 inches of snow a year, with January the snowiest month on the normals.
