The year, day by day
The calendar barely moves in Tacoma Narrows: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 36°F near December 21 and 77°F near July 27.
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 36°F around December 21.
Where the wet dates fall
The likeliest wet date is January 4, when 69% of years recorded at least a hundredth of an inch. The driest is July 26 at 12%. Summed across the calendar, that is about 169 wet dates a year.
The widest day
July 25 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Where Tacoma Narrows Stands Nationally
Days and nights track unusually close together; the widest normal swing, about 22°F, is narrower than most stations record.
Tacoma Narrows earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Tacoma Narrows's wet season runs through the cold months
December, January and February carry 38% of the year's precipitation here, while June through August contribute 7%. 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 24.1°F seasonal spread.
- Wettest month
- November, 7.2"
- Driest month
- July, 0.7"
- Wettest three months
- November, January, December (45% 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 Tacoma Narrows's precipitation splits across the calendar
About 168 days a year record measurable precipitation here, carrying 42.0" 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.

Data-derived climate profile
How Tacoma Narrows's climate pattern fits together
heating led · moderate · low swing
Heating is the larger measured load in Tacoma Narrows, at 4,884 degree days versus 132 for cooling. Unlike a strongly continental record, however, its 24.1°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
The frost-free window extends for about 255 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
Temperature varies within a narrow 24.1°F band across the normal year. August and December mark the typical warm and cold ends of the calendar. The annual average is 52°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
Tacoma Narrows's 42.0 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Tacoma Narrows'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 Tacoma Narrows, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Tacoma Narrows's primary station: TACOMA NARROWS AP (USW00094274). 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 Tacoma Narrows; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Tacoma Narrows comes from its primary NOAA station record.
