The year, day by day
Johnson Pass works both ends of the calendar. Normal highs climb to 92°F by July 23 and hold at or above 90°F on 33 dates, then normal lows drop to freezing or below on 157 dates, bottoming at 18°F around December 24.
When the heat sits
Normal highs reach 90°F from July 9 through August 10, covering 33 dates. The broader mild season, normal highs of 70°F or more, runs May 17 to September 30.
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 5, then returns to freezing around November 1, covering 157 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 April 8, when 31% of years recorded at least a hundredth of an inch. The driest is June 26 at 15%. Summed across the calendar, that is about 89 wet dates a year.
The widest day
July 1 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Johnson Pass 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 29%, with neither reaching the 35% that would mark a distinct wet season. Johnson Pass has no dry season to plan around, though it does carry a wide 46.8°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 1.9" and July 0.8". The three wettest months together take 33% 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.
Johnson Pass is dry, and what does fall arrives gently
Only about 89 days a year record measurable precipitation here, 24% of the calendar, and they carry 15.7" between them. At roughly 0.18 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 June at about 5.
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 Johnson Pass
Johnson Pass averages 68.3 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 33 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: 68.3 inches of depth.
- Days recording measurable snow: about 33 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 43% 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 Johnson Pass
heating led · dry · mid swing
Johnson Pass's energy balance leans toward cold weather: 6,314 annual heating degree days against 794 for cooling. Its 46.8°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. Johnson Pass coldest normal
December
The monthly mean of 28°F (-2°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.
-
2. Johnson Pass typical freeze period
January through December
The station reports average freezing days from January through December.
-
3. Johnson Pass snow peak
February
Johnson Pass averages 68.3 inches of snow a year, with February the snowiest month on the normals.

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 Johnson Pass; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
