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 37°F around December 21.

Where the wet dates fall

The likeliest wet date is December 20, when 64% of years recorded at least a hundredth of an inch. The driest is July 30 at 15%. Summed across the calendar, that is about 163 wet dates a year.

The widest day

July 25 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Seattle Sand Point Wsfo'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 9%. 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 25.3°F seasonal spread.

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 Seattle Sand Point Wsfo's precipitation splits across the calendar

About 163 days a year record measurable precipitation here, carrying 37.8" between them, or roughly 0.23 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 Seattle Sand Point Wsfo, but rarely amounts to much

The normals record 3.8 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 3 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 Seattle Sand Point Wsfo's climate pattern fits together

heating led · moderate · low swing

Heating is the larger measured load in Seattle Sand Point Wsfo, at 4,483 degree days versus 211 for cooling. Unlike a strongly continental record, however, its 25.3°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 260 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 25.3°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.

Seattle Sand Point Wsfo's 37.8 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 3.8 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.

These labels group NOAA 1991-2020 normals from Seattle Sand Point Wsfo'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 Seattle Sand Point Wsfo, 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 Seattle Sand Point Wsfo's primary station: SEATTLE SAND PT WSFO (USW00094290). 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 Seattle Sand Point Wsfo; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
