The year, day by day
Malheur Branch Exp Stn works both ends of the calendar. Normal highs climb to 95°F by July 25 and hold at or above 90°F on 47 dates, then normal lows drop to freezing or below on 133 dates, bottoming at 22°F around December 24.
When the heat sits
Normal highs reach 90°F from July 6 through August 21, covering 47 dates. The broader mild season, normal highs of 70°F or more, runs May 3 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 12, then returns to freezing around November 1, covering 133 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 30, when 37% of years recorded at least a hundredth of an inch. The driest is July 24 at 8%. Summed across the calendar, that is about 91 wet dates a year.
The widest day
August 29 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Malheur Branch Exp Stn Stands Nationally
Aridity defines the water calendar: about 11 inches in a normal year lands this among the driest tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 35°F between the normal high and low.
Malheur Branch Exp Stn earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Malheur Branch Exp Stn's wet season runs through the cold months
December, January and February carry 37% 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 wide 46°F gap between its warmest and coldest month.
- Wettest month
- December, 1.6"
- Driest month
- August, 0.2"
- Wettest three months
- December, January, May (40% 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.
Malheur Branch Exp Stn is dry, and what does fall arrives gently
Only about 91 days a year record measurable precipitation here, 25% of the calendar, and they carry 10.7" 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 11 wet days; the driest is July 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 Malheur Branch Exp Stn
Malheur Branch Exp Stn averages 15.4 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 11 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: 15.4 inches of depth.
- Days recording measurable snow: about 11 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 14% 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.

Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Malheur Branch Exp Stn; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
