The year, day by day
Summer here tops out rather than builds: the warmest normal high is 78°F around July 13, short of 90°F on every date, while 181 dates carry a normal low at or below freezing, the coldest 3°F near January 25.
The freezing stretch
The normal low stays at or below 32°F into April 23, then returns to freezing around October 26, covering 181 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 January 6, when 58% of years recorded at least a hundredth of an inch. The driest is September 2 at 36%. Summed across the calendar, that is about 168 wet dates a year.
The widest day
September 7 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Where Tupper Lake Sunmount Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 181 nights a year, more than most ranked stations.
Tupper Lake Sunmount earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Tupper Lake Sunmount 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 21%, with neither reaching the 35% that would mark a distinct wet season. Tupper Lake Sunmount has no dry season to plan around, though it does carry a wide 51.2°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: June averages 4.5" and February 2.6". The three wettest months together take 29% 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.
How Tupper Lake Sunmount's precipitation splits across the calendar
About 168 days a year record measurable precipitation here, carrying 45.1" 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 Tupper Lake Sunmount's climate pattern fits together
heating led · wet · mid swing
Tupper Lake Sunmount's energy balance leans toward cold weather: 8,746 annual heating degree days against 222 for cooling. Its 51.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 135 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 Tupper Lake Sunmount's middle-range seasonal profile. The measured spread is 51.2°F. The annual average is 42°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Tupper Lake Sunmount carries 45.0 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Tupper Lake Sunmount'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 Tupper Lake Sunmount, 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 Tupper Lake Sunmount's primary station: TUPPER LAKE SUNMOUNT (USC00308631). 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 Tupper Lake Sunmount; 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 Tupper Lake Sunmount comes from its primary NOAA station record.
