The year, day by day
Summer here tops out rather than builds: the warmest normal high is 68°F around June 29, short of 90°F on every date, while 274 dates carry a normal low at or below freezing, the coldest -1°F near January 10.
The freezing stretch
The normal low stays at or below 32°F into June 4, then returns to freezing around September 5, covering 274 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.
The widest day
June 4 carries the biggest normal gap between afternoon and dawn, 31°F between the normal high and the normal low.

Where Chulitna Rvr Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 274 nights a year, placing this among the most frost-prone tenth of ranked stations.
Chulitna Rvr earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Chulitna Rvr spreads its precipitation across the year
Neither half of the year dominates here: June through August take 34% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. Chulitna Rvr has no dry season to plan around, though it does carry a 44.2°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 5.5" and April 1.1". The three wettest months together take 45% 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.

Data-derived climate profile
How Chulitna Rvr's climate pattern fits together
heating led · moderate · mid swing
Chulitna Rvr's energy balance leans toward cold weather: 12,744 annual heating degree days against 3 for cooling. Its 44.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
A frost-free growing-season length is not available for Chulitna Rvr. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
July and January mark the typical warm and cold ends of the calendar in Chulitna Rvr's middle-range seasonal profile. The measured spread is 44.2°F. The annual average is 30°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Chulitna Rvr's 31.5 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 Chulitna Rvr'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 Chulitna Rvr, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Chulitna Rvr's primary station: CHULITNA RVR (USC00501926). 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 Chulitna Rvr; 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 Chulitna Rvr comes from its primary NOAA station record.
