The year, day by day
The calendar barely moves in Longview: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 34°F near December 17 and 81°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 17.
Where the wet dates fall
The likeliest wet date is December 20, when 79% of years recorded at least a hundredth of an inch. The driest is July 29 at 14%. Summed across the calendar, that is about 192 wet dates a year.
The widest day
August 25 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Longview'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 8%. 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 26.2°F seasonal spread.
- Wettest month
- November, 7.2"
- Driest month
- July, 0.6"
- Wettest three months
- November, December, January (43% 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 Longview's precipitation splits across the calendar
About 192 days a year record measurable precipitation here, carrying 48.1" between them, or roughly 0.25 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.

Data-derived climate profile
How Longview's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Longview, at 4,545 degree days versus 243 for cooling. Unlike a strongly continental record, however, its 26.2°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Longview's frost-free season lasts about 211 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Longview's 26.2°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 53°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Alongside its heating load, Longview carries 48.1 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. 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 Longview'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 Longview, not an official NOAA class or a year-ahead forecast.
