The year, day by day
Grand Junction Walker Fld works both ends of the calendar. Normal highs climb to 95°F by July 15 and hold at or above 90°F on 66 dates, then normal lows drop to freezing or below on 135 dates, bottoming at 16°F around January 1.
When the heat sits
Normal highs reach 90°F from June 17 through August 21, covering 66 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 17, then returns to freezing around November 4, covering 135 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 13, when 24% of years recorded at least a hundredth of an inch. The driest is June 22 at 12%. Summed across the calendar, that is about 72 wet dates a year.
The widest day
June 14 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Grand Junction Walker Fld Stands Nationally
Aridity defines the water calendar: about 9 inches in a normal year lands this among the driest tenth of ranked stations.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 66 days a year, more than four out of five ranked stations record.
Grand Junction Walker Fld earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Grand Junction Walker Fld spreads its precipitation across the year
Neither half of the year dominates here: June through August take 21% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. Grand Junction Walker Fld has no dry season to plan around, though it does carry a wide 51.5°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: September averages 1.2" and June 0.4". The three wettest months together take 35% 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.
Grand Junction Walker Fld is dry, and what does fall arrives gently
Only about 72 days a year record measurable precipitation here, 20% of the calendar, and they carry 9.1" between them. At roughly 0.13 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 7 wet days; the driest is June 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 Grand Junction Walker Fld
Grand Junction Walker Fld averages 17.7 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 18 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: 17.7 inches of depth.
- Days recording measurable snow: about 18 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 20% 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 Grand Junction Walker Fld; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
