The year, day by day
The calendar barely moves in Drain: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 34°F near December 23 and 87°F near July 30.
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 34°F around December 23.
Where the wet dates fall
The likeliest wet date is November 25, when 67% of years recorded at least a hundredth of an inch. The driest is July 30 at 7%. Summed across the calendar, that is about 158 wet dates a year.
The widest day
August 27 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Drain Stands Nationally
Daily temperature swings run wider than most of the country, peaking near 35°F between the normal high and low.
Drain earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Drain's wet season runs through the cold months
December, January and February carry 45% of the year's precipitation here, while June through August contribute 4%. 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 26.4°F seasonal spread.
- Wettest month
- December, 8.5"
- Driest month
- July, 0.3"
- Wettest three months
- December, January, November (48% 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 Drain's precipitation splits across the calendar
About 158 days a year record measurable precipitation here, carrying 47.6" between them, or roughly 0.30 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.
Drain'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 Drain's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Drain, at 4,300 degree days versus 339 for cooling. Unlike a strongly continental record, however, its 26.4°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Drain's frost-free season lasts about 192 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Drain's 26.4°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 54°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Alongside its heating load, Drain carries 47.6 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 Drain'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 Drain, not an official NOAA class or a year-ahead forecast.
