The year, day by day
Summer here tops out rather than builds: the warmest normal high is 75°F around June 29, short of 90°F on every date, while 213 dates carry a normal low at or below freezing, the coldest -13°F near January 8.
The freezing stretch
The normal low stays at or below 32°F into April 28, then returns to freezing around September 29, covering 213 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 August 5, when 42% of years recorded at least a hundredth of an inch. The driest is April 6 at 13%. Summed across the calendar, that is about 95 wet dates a year.
The widest day
May 25 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Where Nenana Muni Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 213 nights a year, placing this among the most frost-prone tenth of ranked stations.
A drier-than-most normal water year — around 12 inches, below what four out of five ranked stations collect.
Nenana Muni earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Nenana Muni runs a summer-peaked wet season
52% of Nenana Muni'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 August at 2.3", on a wide 66.2°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: August, July, June, taking 52% of the annual total between them.
- Driest month: April at 0.3".
- Winter share: 13% 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.
Nenana Muni is dry, and what does fall arrives gently
Only about 94 days a year record measurable precipitation here, 26% of the calendar, and they carry 12.4" 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 August at about 13 wet days; the driest is April 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.

Scarce-water calendar
Where Nenana Muni's limited precipitation lands
heating led · dry · high swing
Winter and seasonal range jointly define this record. Nenana Muni logs 12,753 heating degree days, more than twice its 66 cooling total, while the typical coldest-to-warmest-month gap reaches 66.2°F. The annual mean therefore compresses two materially different seasons.
Only about 119 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 this dry, high-range record. The gap is 66.2°F, so a single annual figure is especially lossy; the annual average is 30°f. Compare monthly temperature and precipitation together before drawing a seasonal conclusion about Nenana Muni.
Nenana Muni's cold-season load does not imply a wet climate. Annual precipitation is 12.4 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Nenana Muni's primary station: NENANA MUNI AP (USW00026435). 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 Nenana Muni; 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 Nenana Muni comes from its primary NOAA station record.
