The year, day by day
The calendar barely moves in Plymouth: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 33°F near January 21 and 90°F near July 7.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 33°F around January 21.
Where the wet dates fall
The likeliest wet date is August 1, when 43% of years recorded at least a hundredth of an inch. The driest is October 23 at 33%. Summed across the calendar, that is about 136 wet dates a year.
The widest day
April 11 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Where Plymouth Stands Nationally
The normal water year runs well above the national norm at roughly 55 inches.
Plymouth earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Plymouth spreads its precipitation across the year
Neither half of the year dominates here: June through August take 32% of the annual total and December through February 20%, with neither reaching the 35% that would mark a distinct wet season. Plymouth has no dry season to plan around, though it does carry a 36°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 6.6" and February 3.4". The three wettest months together take 34% 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 Plymouth, it arrives in quantity
54.6" of precipitation falls across only about 136 wet days here, averaging 0.40 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 136 a year, 37% of all days
- Average depth per wet day
- 0.40 inches
- Most wet days
- August, about 13
- Fewest wet days
- October, about 10
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.
Snow reaches Plymouth, but rarely amounts to much
The normals record 1.4 inches of snow a year here, most likely in January. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 1 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Plymouth's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Plymouth averages 54.6 inches of precipitation a year. Annual snowfall totals 1.4 inches. The monthly table supplies the seasonal distribution hidden by that annual total.
July and January mark the typical warm and cold ends of the calendar in Plymouth's middle-range seasonal profile. The measured spread is 36.0°F. The annual average is 62°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Plymouth's normal, at 2,843 and 1,803 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
A roughly 221-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.
These labels group NOAA 1991-2020 normals from Plymouth's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Plymouth, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
