The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 21, short of 90°F on every date, while 238 dates carry a normal low at or below freezing, the coldest 10°F near January 4.
The freezing stretch
The normal low stays at or below 32°F into May 16, then returns to freezing around September 22, covering 238 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 February 17, when 19% of years recorded at least a hundredth of an inch. The driest is June 22 at 7%. Summed across the calendar, that is about 41 wet dates a year.
The widest day
September 14 carries the biggest normal gap between afternoon and dawn, 44°F between the normal high and the normal low.

Where Bridgeport Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 238 nights a year, placing this among the most frost-prone tenth of ranked stations.
Aridity defines the water calendar: about 10 inches in a normal year lands this among the driest tenth of ranked stations.
Bridgeport earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Bridgeport's wet season runs through the cold months
December, January and February carry 49% of the year's precipitation here, while June through August contribute 13%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 37.5°F seasonal spread.
- Wettest month
- January, 2.0"
- Driest month
- September, 0.2"
- Wettest three months
- January, December, February (49% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
How Bridgeport's precipitation splits across the calendar
About 40 days a year record measurable precipitation here, carrying 10.2" between them, or roughly 0.25 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 Bridgeport
Bridgeport averages 31.9 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 17 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: 31.9 inches of depth.
- Days recording measurable snow: about 17 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 31% 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.

Bridgeport's energy balance leans toward cold weather: 7,567 annual heating degree days against 68 for cooling. Its 37.5°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 Bridgeport. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
