The year, day by day
The year in Roseburg Kqen runs from a mild 36°F around December 24 to 90°F at the peak near July 26, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from July 24 through August 4, covering 12 dates. The broader mild season, normal highs of 70°F or more, runs May 4 to October 14.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
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 December 24.
Where the wet dates fall
The likeliest wet date is November 29, when 62% of years recorded at least a hundredth of an inch. The driest is July 27 at 5%. Summed across the calendar, that is about 138 wet dates a year.
The widest day
September 6 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Roseburg Kqen Stands Nationally
Daily temperature swings run wider than most of the country, peaking near 33°F between the normal high and low.

Roseburg Kqen'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 5%. 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 29.4°F seasonal spread.
- Wettest month
- December, 6.3"
- Driest month
- August, 0.3"
- Wettest three months
- December, January, November (49% 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 Roseburg Kqen's precipitation splits across the calendar
About 138 days a year record measurable precipitation here, carrying 33.7" between them, or roughly 0.24 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.
Roseburg Kqen'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 Roseburg Kqen's climate pattern fits together
heating led · moderate · low swing
Heating is the larger measured load in Roseburg Kqen, at 3,809 degree days versus 690 for cooling. Unlike a strongly continental record, however, its 29.4°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 240 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 29.4°F band across the normal year. July and December mark the typical warm and cold ends of the calendar. The annual average is 56°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
Roseburg Kqen's 33.7 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Recorded annual snowfall is negligible. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Roseburg Kqen'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 Roseburg Kqen, not an official NOAA class or a year-ahead forecast.

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 Roseburg Kqen; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
