The year, day by day
Summer here tops out rather than builds: the warmest normal high is 73°F around June 28, short of 90°F on every date, while 227 dates carry a normal low at or below freezing, the coldest -19°F near January 10.
The freezing stretch
The normal low stays at or below 32°F into May 4, then returns to freezing around September 21, covering 227 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 July 30, when 45% of years recorded at least a hundredth of an inch. The driest is April 9 at 12%. Summed across the calendar, that is about 96 wet dates a year.
The widest day
March 14 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Where Eielson Fld Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 227 nights a year, placing this among the most frost-prone tenth of ranked stations.
A drier-than-most normal water year — around 13 inches, below what four out of five ranked stations collect.
Eielson Fld earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Eielson Fld runs a summer-peaked wet season
57% of Eielson Fld's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is July at 2.7", on a wide 69.8°F gap between its warmest and coldest month. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: July, August, June, taking 57% of the annual total between them.
- Driest month: April at 0.3".
- Winter share: 10% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
Eielson Fld is dry, and what does fall arrives gently
Only about 97 days a year record measurable precipitation here, 26% of the calendar, and they carry 12.9" 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 July at about 13 wet days; the driest is April 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 Eielson Fld
Eielson Fld averages 67.7 inches of snowfall a year, with November the snowiest month on the normals, spread across roughly 54 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: 67.7 inches of depth.
- Days recording measurable snow: about 54 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 53% 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 Eielson Fld
heating led · dry · high swing
Winter and seasonal range jointly define this record. Eielson Fld logs 13,878 heating degree days, more than twice its 34 cooling total, while the typical coldest-to-warmest-month gap reaches 69.8°F. The annual mean therefore compresses two materially different seasons.
Only about 104 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 Eielson Fld; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
