The year, day by day
The calendar barely moves in Langlois: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 39°F near December 17 and 70°F near August 28.
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 39°F around December 17.
Where the wet dates fall
The likeliest wet date is December 13, when 69% of years recorded at least a hundredth of an inch. The driest is July 29 at 7%. Summed across the calendar, that is about 159 wet dates a year.
The widest day
September 24 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Where Langlois Stands Nationally
This is one of the wettest normals climates ranked: about 70 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 21°F.
Langlois earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Langlois's wet season runs through the cold months
December, January and February carry 47% of the year's precipitation here, while June through August contribute 4%. 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 14.4°F seasonal spread.
- Wettest month
- December, 12.2"
- Driest month
- July, 0.3"
- Wettest three months
- December, January, November (48% 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.
When it rains in Langlois, it arrives in quantity
70.4" of precipitation falls across only about 159 wet days here, averaging 0.44 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 159 a year, 44% of all days
- Average depth per wet day
- 0.44 inches
- Most wet days
- December, about 21
- Fewest wet days
- July, about 3
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.
Langlois'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.

How Langlois's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Langlois, at 4,420 degree days versus 5 for cooling. Unlike a strongly continental record, however, its 14.4°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 258 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.
Langlois's 14.4°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, Langlois carries 70.3 inches of precipitation in a normal year, inside PlainClimate's wet range. Recorded annual snowfall is negligible. 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 Langlois'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 Langlois, not an official NOAA class or a year-ahead forecast.
