The year, day by day
The calendar barely moves in Mcminnville Muni: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 34°F near December 20 and 85°F near July 27.
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 20.
Where the wet dates fall
The likeliest wet date is November 24, when 64% of years recorded at least a hundredth of an inch. The driest is July 27 at 6%. Summed across the calendar, that is about 158 wet dates a year.
The widest day
July 27 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Mcminnville Muni's wet season runs through the cold months
December, January and February carry 43% 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 27°F seasonal spread.
- Wettest month
- December, 6.5"
- Driest month
- July, 0.3"
- Wettest three months
- December, November, January (47% 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 Mcminnville Muni's precipitation splits across the calendar
About 158 days a year record measurable precipitation here, carrying 37.6" 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.

Data-derived climate profile
How Mcminnville Muni's climate pattern fits together
heating led · moderate · low swing
Heating is the larger measured load in Mcminnville Muni, at 4,694 degree days versus 284 for cooling. Unlike a strongly continental record, however, its 27.0°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Mcminnville Muni's frost-free season lasts about 194 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Temperature varies within a narrow 27.0°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.
Mcminnville Muni's 37.6 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Mcminnville Muni'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 Mcminnville Muni, 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 Mcminnville Muni's primary station: MCMINNVILLE MUNI AP (USW00094273). 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 Mcminnville Muni; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Mcminnville Muni comes from its primary NOAA station record.
