The year, day by day
Summer here tops out rather than builds: the warmest normal high is 76°F around July 17, short of 90°F on every date, while 180 dates carry a normal low at or below freezing, the coldest 2°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into April 22, then returns to freezing around October 26, covering 180 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
May 29 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Data-derived climate profile
How Patten's climate pattern fits together
heating led · mid swing
Patten's energy balance leans toward cold weather: 9,033 annual heating degree days against 180 for cooling. Its 53.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 140 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 Patten's middle-range seasonal profile. The measured spread is 53.0°F. The annual average is 41°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Patten'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 Patten'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 Patten, 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 Patten's primary station: PATTEN 2 (USC00176594). 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 2357115), not an incorporated municipality. Match rule for Patten: 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 Patten 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.
