The year, day by day
The calendar barely moves in Otis: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 37°F near December 18 and 72°F near August 17.
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 37°F around December 18.
Where the wet dates fall
The likeliest wet date is December 24, when 88% of years recorded at least a hundredth of an inch. The driest is July 29 at 19%. Summed across the calendar, that is about 205 wet dates a year.
The widest day
September 5 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Where Otis Stands Nationally
This is one of the wettest normals climates ranked: about 96 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Days and nights track unusually close together; the widest normal swing, about 22°F, is narrower than most stations record.
Otis earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Otis's wet season runs through the cold months
December, January and February carry 42% of the year's precipitation here, while June through August contribute 6%. 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 19.5°F seasonal spread.
- Wettest month
- December, 15.8"
- Driest month
- July, 0.9"
- Wettest three months
- December, January, November (46% 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 Otis, it arrives in quantity
96.4" of precipitation falls across only about 205 wet days here, averaging 0.47 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 205 a year, 56% of all days
- Average depth per wet day
- 0.47 inches

- December, about 27
- Fewest wet days
- July, about 6
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 Otis, but rarely amounts to much
The normals record 0.1 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.
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 Otis's climate pattern fits together
heating led · wet · low swing
Heating is the larger measured load in Otis, at 4,863 degree days versus 35 for cooling. Unlike a strongly continental record, however, its 19.5°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Otis's frost-free season lasts about 226 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Otis's 19.5°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 52°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Alongside its heating load, Otis carries 96.4 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 Otis'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 Otis, 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 Otis's primary station: OTIS 2 NE (USC00356366). 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 Otis; 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 Otis comes from its primary NOAA station record.
