The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 24, short of 90°F on every date, while 264 dates carry a normal low at or below freezing, the coldest 14°F near December 24.
The freezing stretch
The normal low stays at or below 32°F into May 28, then returns to freezing around September 8, covering 264 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 December 27, when 45% of years recorded at least a hundredth of an inch. The driest is August 21 at 7%. Summed across the calendar, that is about 99 wet dates a year.
The widest day
September 10 carries the biggest normal gap between afternoon and dawn, 46°F between the normal high and the normal low.

Where Chemult Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 264 nights a year, placing this among the most frost-prone tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 46°F, sharper than nine in ten ranked stations see.
Chemult earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Chemult's wet season runs through the cold months
December, January and February carry 49% of the year's precipitation here, while June through August contribute 9%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 35.2°F seasonal spread.
- Wettest month
- December, 5.3"
- Driest month
- July, 0.5"
- Wettest three months
- December, January, February (49% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
How Chemult's precipitation splits across the calendar
About 97 days a year record measurable precipitation here, carrying 26.5" between them, or roughly 0.27 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
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 Chemult's climate pattern fits together
heating led · moderate · mid swing
Chemult's energy balance leans toward cold weather: 8,521 annual heating degree days against 51 for cooling. Its 35.2°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 Chemult. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
July and December mark the typical warm and cold ends of the calendar in Chemult's middle-range seasonal profile. The measured spread is 35.2°F. The annual average is 42°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Chemult's 26.5 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 Chemult'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 Chemult, not an official NOAA class or a year-ahead forecast.
