The year, day by day
Mcdermitt works both ends of the calendar. Normal highs climb to 94°F by July 24 and hold at or above 90°F on 41 dates, then normal lows drop to freezing or below on 211 dates, bottoming at 15°F around December 24.
When the heat sits
Normal highs reach 90°F from July 8 through August 17, covering 41 dates. The broader mild season, normal highs of 70°F or more, runs May 13 to October 8.
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 April 28, then returns to freezing around October 1, covering 211 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 17, when 28% of years recorded at least a hundredth of an inch. The driest is August 23 at 7%. Summed across the calendar, that is about 70 wet dates a year.
The widest day
August 20 carries the biggest normal gap between afternoon and dawn, 45°F between the normal high and the normal low.

Where Mcdermitt Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 211 nights a year, placing this among the most frost-prone tenth of ranked stations.
Aridity defines the water calendar: about 8 inches in a normal year lands this among the driest tenth of ranked stations.

Mcdermitt spreads its precipitation across the year
Neither half of the year dominates here: June through August take 17% of the annual total and December through February 26%, with neither reaching the 35% that would mark a distinct wet season. Mcdermitt has no dry season to plan around, though it does carry a 42.6°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 1.2" and August 0.2". The three wettest months together take 39% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
Mcdermitt is dry, and what does fall arrives gently
Only about 70 days a year record measurable precipitation here, 19% of the calendar, and they carry 7.8" between them. At roughly 0.11 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 April at about 9 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 Mcdermitt
Mcdermitt averages 20.8 inches of snowfall a year, with December 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: 20.8 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 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.

Mcdermitt's energy balance leans toward cold weather: 6,695 annual heating degree days against 384 for cooling. Its 42.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
A frost-free growing-season length is not available for Mcdermitt. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
