The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 19, short of 90°F on every date, while 123 dates carry a normal low at or below freezing, the coldest 20°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into March 26, then returns to freezing around November 25, covering 123 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 May 11, when 37% of years recorded at least a hundredth of an inch. The driest is August 29 at 27%. Summed across the calendar, that is about 120 wet dates a year.
The widest day
May 8 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Norwich Public Utility Plt spreads its precipitation across the year
Neither half of the year dominates here: June through August take 24% of the annual total and December through February 24%, with neither reaching the 35% that would mark a distinct wet season. Norwich Public Utility Plt has no dry season to plan around, though it does carry a 44.9°F seasonal spread.
The gap between the wettest and driest month still matters: March averages 5.1" and July 3.6". 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.
When it rains in Norwich Public Utility Plt, it arrives in quantity
52.2" of precipitation falls across only about 120 wet days here, averaging 0.43 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 120 a year, 33% of all days
- Average depth per wet day
- 0.43 inches
- Most wet days
- May, about 11
- Fewest wet days
- September, about 9
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.
Winter brings real snow to Norwich Public Utility Plt
Norwich Public Utility Plt averages 27.8 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 11 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 27.8 inches of depth.
- Days recording measurable snow: about 11 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 5% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

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 Norwich Public Utility Plt; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
