The year, day by day
Summer here tops out rather than builds: the warmest normal high is 90°F around July 29, short of 90°F on every date, while 195 dates carry a normal low at or below freezing, the coldest 13°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into April 22, then returns to freezing around October 11, covering 195 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 January 1, when 27% of years recorded at least a hundredth of an inch. The driest is July 8 at 12%. Summed across the calendar, that is about 72 wet dates a year.
The widest day
August 20 carries the biggest normal gap between afternoon and dawn, 38°F between the normal high and the normal low.

Where Aberdeen Exp Stn Stands Nationally
Aridity defines the water calendar: about 10 inches in a normal year lands this among the driest tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 38°F, sharper than nine in ten ranked stations see.

Aberdeen Exp Stn spreads its precipitation across the year
Neither half of the year dominates here: June through August take 19% of the annual total and December through February 26%, with neither reaching the 35% that would mark a distinct wet season. Aberdeen Exp Stn has no dry season to plan around, though it does carry a wide 46.1°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 1.2" and July 0.4". 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.
Aberdeen Exp Stn 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 9.6" 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 December at about 8 wet days; the driest is July at about 4.
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 Aberdeen Exp Stn
Aberdeen Exp Stn averages 25.2 inches of snowfall a year, with January 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: 25.2 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 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.

Snow and freeze rhythm
When cold and snow define Aberdeen Exp Stn
heating led · dry · mid swing
Aberdeen Exp Stn's energy balance leans toward cold weather: 7,455 annual heating degree days against 346 for cooling. Its 46.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 122 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.

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 Aberdeen Exp Stn; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
