The year, day by day
The calendar barely moves in Molalla: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 35°F near December 18 and 83°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 35°F around December 18.
Where the wet dates fall
The likeliest wet date is December 20, when 62% of years recorded at least a hundredth of an inch. The driest is July 31 at 8%. Summed across the calendar, that is about 158 wet dates a year.
The widest day
August 28 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Molalla's wet season runs through the cold months
December, January and February carry 36% of the year's precipitation here, while June through August contribute 7%. 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 28.7°F seasonal spread.
- Wettest month
- November, 6.9"
- Driest month
- July, 0.6"
- Wettest three months
- November, December, January (42% 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 Molalla's precipitation splits across the calendar
About 158 days a year record measurable precipitation here, carrying 46.4" between them, or roughly 0.29 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 Molalla's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Molalla, at 4,451 degree days versus 390 for cooling. Unlike a strongly continental record, however, its 28.7°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 248 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.
Molalla's 28.7°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, Molalla carries 46.4 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 Molalla'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 Molalla, not an official NOAA class or a year-ahead forecast.
