The year, day by day
The calendar barely moves in Tillamook: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 36°F near February 19 and 69°F near August 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 February 19.
Where the wet dates fall
The likeliest wet date is November 29, when 77% of years recorded at least a hundredth of an inch. The driest is July 28 at 20%. Summed across the calendar, that is about 197 wet dates a year.
The widest day
September 22 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Where Tillamook Stands Nationally
This is one of the wettest normals climates ranked: about 90 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 22°F, is narrower than most stations record.
Tillamook earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Tillamook's wet season runs through the cold months
December, January and February carry 42% 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 16.2°F seasonal spread.
- Wettest month
- December, 14.7"
- Driest month
- July, 0.9"
- Wettest three months
- December, November, January (46% 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.
When it rains in Tillamook, it arrives in quantity
89.8" of precipitation falls across only about 197 wet days here, averaging 0.46 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 197 a year, 54% of all days
- Average depth per wet day
- 0.46 inches
- Most wet days
- December, about 23
- Fewest wet days
- July, about 6
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 Tillamook, but rarely amounts to much
The normals record 0.2 inches of snow a year here, most likely in February. 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 0 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 Tillamook's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Tillamook, at 5,124 degree days versus 10 for cooling. Unlike a strongly continental record, however, its 16.2°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Tillamook's frost-free season lasts about 182 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Tillamook's 16.2°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 51°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Alongside its heating load, Tillamook carries 89.8 inches of precipitation in a normal year, inside PlainClimate's wet range. Recorded annual snowfall is negligible. 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 Tillamook'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 Tillamook, not an official NOAA class or a year-ahead forecast.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Tillamook's primary station: TILLAMOOK (USC00358494). 2 NOAA stations are mapped to the Tillamook area; the primary station's record is used for consistency. For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 4173700). Match rule for Tillamook: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
