The year, day by day
Summer here tops out rather than builds: the warmest normal high is 66°F around July 25, short of 90°F on every date, while 194 dates carry a normal low at or below freezing, the coldest 13°F near January 10.
The freezing stretch
The normal low stays at or below 32°F into April 22, then returns to freezing around October 12, covering 194 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 September 3, when 55% of years recorded at least a hundredth of an inch. The driest is May 5 at 21%. Summed across the calendar, that is about 130 wet dates a year.
The widest day
May 20 carries the biggest normal gap between afternoon and dawn, 17°F between the normal high and the normal low.

Where Anchorage Upper De Armoun Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 17°F.
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 194 nights a year, more than most ranked stations.
Anchorage Upper De Armoun earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Anchorage Upper De Armoun spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 23%, with neither reaching the 35% that would mark a distinct wet season. Anchorage Upper De Armoun has no dry season to plan around, though it does carry a 36.3°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 3.9" and May 0.8". The three wettest months together take 41% 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.
Rain reaches Anchorage Upper De Armoun in small, frequent amounts
Anchorage Upper De Armoun records about 130 days with measurable precipitation a year and 22.4" in total, which works out to roughly 0.17 inches on an average wet day. Precipitation on 36% of all days, arriving that lightly, is the damp many-grey-days pattern rather than the storm-driven one.
Places in this band read as wetter than their annual totals suggest, because what people notice is the number of overcast days, not the depth in the gauge.
- Most wet days: September, about 17 of them.
- Fewest: May, about 6.
- Average depth per wet day: 0.17 inches.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

Data-derived climate profile
How Anchorage Upper De Armoun's climate pattern fits together
heating led · moderate · mid swing
Anchorage Upper De Armoun's energy balance leans toward cold weather: 9,985 annual heating degree days against 10 for cooling. Its 36.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 144 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.
July and January mark the typical warm and cold ends of the calendar in Anchorage Upper De Armoun's middle-range seasonal profile. The measured spread is 36.3°F. The annual average is 38°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Anchorage Upper De Armoun's 22.4 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Anchorage Upper De Armoun's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Anchorage Upper De Armoun, not an official NOAA class or a year-ahead forecast.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Anchorage Upper De Armoun's primary station: ANCHORAGE UPPER DE ARMOUN (USC00500281). For informational purposes only.
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 Anchorage Upper De Armoun; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Anchorage Upper De Armoun comes from its primary NOAA station record.
