The year, day by day
Summer here tops out rather than builds: the warmest normal high is 90°F around July 29, short of 90°F on every date, while 189 dates carry a normal low at or below freezing, the coldest 20°F near December 21.
The freezing stretch
The normal low stays at or below 32°F into April 21, then returns to freezing around October 16, covering 189 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, 42°F between the normal high and the normal low.

Data-derived climate profile
How Saint Regis's climate pattern fits together
heating led · mid swing
Saint Regis's energy balance leans toward cold weather: 7,074 annual heating degree days against 235 for cooling. Its 39.7°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 Saint Regis. 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 Saint Regis's middle-range seasonal profile. The measured spread is 39.7°F. The annual average is 46°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Saint Regis'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 Saint Regis'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 Saint Regis, 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 Saint Regis's primary station: SAINT REGIS 1 NE (USC00247318). 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 Saint Regis; 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 Saint Regis 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.
