The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 23, short of 90°F on every date, while 241 dates carry a normal low at or below freezing, the coldest -5°F near January 29.
The freezing stretch
The normal low stays at or below 32°F into May 16, then returns to freezing around September 19, covering 241 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 22, when 19% of years recorded at least a hundredth of an inch. The driest is November 3 at 8%. Summed across the calendar, that is about 44 wet dates a year.
The widest day
July 16 carries the biggest normal gap between afternoon and dawn, 38°F between the normal high and the normal low.

Where Farson Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 241 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.
Farson earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Farson spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 13%, with neither reaching the 35% that would mark a distinct wet season. Farson has no dry season to plan around, though it does carry a wide 52.5°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 1.5" and February 0.3". The three wettest months together take 43% 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.
Farson is dry, and what does fall arrives gently
Only about 45 days a year record measurable precipitation here, 12% of the calendar, and they carry 7.8" 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 May at about 6 wet days; the driest is November at about 3.
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 Farson
Farson averages 28.4 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 17 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: 28.4 inches of depth.
- Days recording measurable snow: about 17 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 36% 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.
