The year, day by day
The calendar barely moves in Eureka Wfo Woodley Island: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 40°F near December 19 and 64°F near August 25.
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 40°F around December 19.
Where the wet dates fall
The likeliest wet date is December 11, when 55% of years recorded at least a hundredth of an inch. The driest is August 14 at 11%. Summed across the calendar, that is about 128 wet dates a year.
The widest day
October 19 carries the biggest normal gap between afternoon and dawn, 15°F between the normal high and the normal low.

Where Eureka Wfo Woodley Island Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 15°F.
Eureka Wfo Woodley Island earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Eureka Wfo Woodley Island's wet season runs through the cold months
December, January and February carry 51% of the year's precipitation here, while June through August contribute 3%. 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 11.1°F seasonal spread.
- Wettest month
- December, 8.1"
- Driest month
- August, 0.2"
- Wettest three months
- December, January, March (51% 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 Eureka Wfo Woodley Island's precipitation splits across the calendar
About 128 days a year record measurable precipitation here, carrying 40.4" 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.
Eureka Wfo Woodley Island's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile
How Eureka Wfo Woodley Island's climate pattern fits together
heating led · moderate · low swing
Heating is the larger measured load in Eureka Wfo Woodley Island, at 4,506 degree days versus 2 for cooling. Unlike a strongly continental record, however, its 11.1°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 288 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 11.1°F band across the normal year. August and December mark the typical warm and cold ends of the calendar. The annual average is 53°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
Eureka Wfo Woodley Island's 40.4 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Recorded annual snowfall is negligible. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Eureka Wfo Woodley Island'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 Eureka Wfo Woodley Island, 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 Eureka Wfo Woodley Island's primary station: EUREKA WFO WOODLEY ISLAND (USW00024213). 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 Eureka Wfo Woodley Island; 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 Eureka Wfo Woodley Island comes from its primary NOAA station record.
