The year, day by day
Wapato works both ends of the calendar. Normal highs climb to 92°F by July 25 and hold at or above 90°F on 31 dates, then normal lows drop to freezing or below on 134 dates, bottoming at 23°F around December 21.
When the heat sits
Normal highs reach 90°F from July 13 through August 12, covering 31 dates. The broader mild season, normal highs of 70°F or more, runs May 1 to October 9.
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 13, then returns to freezing around November 1, covering 134 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 29, when 32% of years recorded at least a hundredth of an inch. The driest is August 14 at 7%. Summed across the calendar, that is about 68 wet dates a year.
The widest day
September 16 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Where Wapato Stands Nationally
Aridity defines the water calendar: about 8 inches in a normal year lands this among the driest tenth of ranked stations.

Wapato's wet season runs through the cold months
December, January and February carry 39% of the year's precipitation here, while June through August contribute 13%. 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 43.8°F seasonal spread.
- Wettest month
- December, 1.4"
- Driest month
- September, 0.2"
- Wettest three months
- December, January, November (43% 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.
Wapato is dry, and what does fall arrives gently
Only about 68 days a year record measurable precipitation here, 19% of the calendar, and they carry 7.8" between them. At roughly 0.12 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is December at about 10 wet days; the driest is August at about 2.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.
Winter brings real snow to Wapato
Wapato averages 20.4 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 9 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: 20.4 inches of depth.
- Days recording measurable snow: about 9 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 26% 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 Wapato
heating led · dry · mid swing
Wapato's energy balance leans toward cold weather: 5,427 annual heating degree days against 817 for cooling. Its 43.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Wapato's frost-free season lasts about 177 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
