The year, day by day
Summer here tops out rather than builds: the warmest normal high is 78°F around July 18, short of 90°F on every date, while 182 dates carry a normal low at or below freezing, the coldest -1°F near January 26.
The freezing stretch
The normal low stays at or below 32°F into April 25, then returns to freezing around October 27, covering 182 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 July 1, when 45% of years recorded at least a hundredth of an inch. The driest is August 31 at 33%. Summed across the calendar, that is about 139 wet dates a year.
The widest day
May 22 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Bridgewater Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 182 nights a year, more than most ranked stations.
Bridgewater earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Bridgewater spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 23%, with neither reaching the 35% that would mark a distinct wet season. Bridgewater has no dry season to plan around, though it does carry a wide 54.6°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 4.5" and February 2.7". The three wettest months together take 30% 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.
How Bridgewater's precipitation splits across the calendar
About 139 days a year record measurable precipitation here, carrying 44.5" between them, or roughly 0.32 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Winter brings real snow to Bridgewater
Bridgewater averages 94.4 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 38 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: 94.4 inches of depth.
- Days recording measurable snow: about 38 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 21% 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.

Snow and freeze rhythm
When cold and snow define Bridgewater
heating led · moderate · mid swing
Bridgewater's energy balance leans toward cold weather: 9,086 annual heating degree days against 199 for cooling. Its 54.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 116 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.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Bridgewater's primary station: BRIDGEWATER (USC00170833). 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 Bridgewater; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
