The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around July 29, short of 90°F on every date, while 189 dates carry a normal low at or below freezing, the coldest 1°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into April 22, then returns to freezing around October 17, 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 13 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Data-derived climate profile
How Wilton's climate pattern fits together
heating led · high swing
Winter and seasonal range jointly define this record. Wilton logs 9,210 heating degree days, more than twice its 373 cooling total, while the typical coldest-to-warmest-month gap reaches 58.8°F. The annual mean therefore compresses two materially different seasons.
Only about 142 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.
Wilton's calendar has a pronounced split: July and January mark the typical warm and cold ends of the calendar, with 58.8°F between them. The annual average is 41°F. That average is context, while the monthly highs, lows, and precipitation totals describe the lived parts of the year.
A moisture-range label is withheld because Wilton'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 Wilton'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 Wilton, 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 Wilton's primary station: WILTON (USC00329455). 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 an incorporated place (GEOID 3886580). Match rule for Wilton: 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 Wilton 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.
