The year, day by day
The calendar barely moves in Bremerton: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 35°F near December 14 and 78°F near July 29.
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 35°F around December 14.
Where the wet dates fall
The likeliest wet date is January 1, when 65% of years recorded at least a hundredth of an inch. The driest is August 1 at 17%. Summed across the calendar, that is about 168 wet dates a year.
The widest day
July 29 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Bremerton Stands Nationally
This is one of the wettest normals climates ranked: about 57 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Days and nights track unusually close together; the widest normal swing, about 23°F, is narrower than most stations record.
Bremerton earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Bremerton's wet season runs through the cold months
December, January and February carry 44% of the year's precipitation here, while June through August contribute 6%. 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 an unusually narrow 25.9°F seasonal spread.
- Wettest month
- December, 9.9"
- Driest month
- July, 0.8"
- Wettest three months
- December, January, November (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 Bremerton's precipitation splits across the calendar
About 167 days a year record measurable precipitation here, carrying 56.9" between them, or roughly 0.34 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.
Snow reaches Bremerton, but rarely amounts to much
The normals record 3.0 inches of snow a year here, most likely in December. 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 2 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 Bremerton's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Bremerton, at 4,825 degree days versus 193 for cooling. Unlike a strongly continental record, however, its 25.9°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Bremerton's frost-free season lasts about 230 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Bremerton's 25.9°F seasonal spread is compact even though precipitation is abundant. August and December mark the typical warm and cold ends of the calendar. The annual average is 52°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Alongside its heating load, Bremerton carries 56.9 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 3.0 inches. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Bremerton'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 Bremerton, not an official NOAA class or a year-ahead forecast.
