The year, day by day
The calendar barely moves in Grayland: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 37°F near February 14 and 68°F near August 24.
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 February 14.
Where the wet dates fall
The likeliest wet date is January 1, when 74% of years recorded at least a hundredth of an inch. The driest is August 11 at 30%. Summed across the calendar, that is about 205 wet dates a year.
The widest day
September 23 carries the biggest normal gap between afternoon and dawn, 18°F between the normal high and the normal low.

Where Grayland Stands Nationally
This is one of the wettest normals climates ranked: about 75 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 18°F.
Grayland earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Grayland's wet season runs through the cold months
December, January and February carry 40% 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 17.2°F seasonal spread.
- Wettest month
- November, 11.7"
- Driest month
- July, 1.1"
- Wettest three months
- November, January, December (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 Grayland, it arrives in quantity
75.2" of precipitation falls across only about 204 wet days here, averaging 0.37 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 204 a year, 56% of all days
- Average depth per wet day
- 0.37 inches
- Most wet days
- March, about 23
- Fewest wet days
- August, about 9
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.
Grayland'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 Grayland's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Grayland, at 5,191 degree days versus 12 for cooling. Unlike a strongly continental record, however, its 17.2°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Grayland's frost-free season lasts about 223 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Grayland's 17.2°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, Grayland carries 75.2 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 Grayland'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 Grayland, not an official NOAA class or a year-ahead forecast.
