The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 10, short of 90°F on every date, while 35 dates carry a normal low at or below freezing, the coldest 31°F near January 15.
The freezing stretch
Freezing normal lows persist into February 4, covering 35 dates.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
Where the wet dates fall
The likeliest wet date is February 22, when 43% of years recorded at least a hundredth of an inch. The driest is September 14 at 29%. Summed across the calendar, that is about 137 wet dates a year.
The widest day
April 14 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

McMinnville spreads its precipitation across the year
Neither half of the year dominates here: June through August take 24% of the annual total and December through February 28%, with neither reaching the 35% that would mark a distinct wet season. McMinnville has no dry season to plan around, though it does carry a 37.3°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 5.5" and October 3.2". The three wettest months together take 29% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
When it rains in McMinnville, it arrives in quantity
54.4" of precipitation falls across only about 136 wet days here, averaging 0.40 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 136 a year, 37% of all days
- Average depth per wet day
- 0.40 inches
- Most wet days
- March, about 13
- Fewest wet days
- September, 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.
Snow reaches McMinnville, but rarely amounts to much
The normals record 4.1 inches of snow a year here, most likely in January. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 4 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How McMinnville's climate pattern fits together
heating led · wet · mid swing
McMinnville's energy balance leans toward cold weather: 3,286 annual heating degree days against 1,565 for cooling. Its 37.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
McMinnville's frost-free season lasts about 206 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in McMinnville's middle-range seasonal profile. The measured spread is 37.3°F. The annual average is 60°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, McMinnville carries 54.4 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 4.1 inches. 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 McMinnville'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, not an official NOAA class or a year-ahead forecast.
