The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around August 1, short of 90°F on every date, while 244 dates carry a normal low at or below freezing, the coldest 8°F near February 14.
The freezing stretch
The normal low stays at or below 32°F into May 15, then returns to freezing around September 15, covering 244 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
August 8 carries the biggest normal gap between afternoon and dawn, 45°F between the normal high and the normal low.

Data-derived climate profile
How Polebridge's climate pattern fits together
heating led · mid swing
Polebridge's energy balance leans toward cold weather: 9,281 annual heating degree days against 43 for cooling. Its 40.3°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 Polebridge. 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 Polebridge's middle-range seasonal profile. The measured spread is 40.3°F. The annual average is 40°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Polebridge's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Polebridge'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 Polebridge, 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 Polebridge's primary station: POLEBRIDGE (USC00246615). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as a census-designated place (GEOID 3058675), not an incorporated municipality. Match rule for Polebridge: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Polebridge comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
