The year, day by day
Summer here tops out rather than builds: the warmest normal high is 64°F around July 29, short of 90°F on every date, while 166 dates carry a normal low at or below freezing, the coldest 21°F near January 7.
The freezing stretch
The normal low stays at or below 32°F into April 14, then returns to freezing around November 1, covering 166 dates in all.
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 October 12, when 78% of years recorded at least a hundredth of an inch. The driest is May 23 at 50%. Summed across the calendar, that is about 232 wet dates a year.
The widest day
May 24 carries the biggest normal gap between afternoon and dawn, 20°F between the normal high and the normal low.

Where Snettisham Pwr Plt Stands Nationally
This is one of the wettest normals climates ranked: about 190 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 20°F.
Snettisham Pwr Plt earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Snettisham Pwr Plt spreads its precipitation across the year
Neither half of the year dominates here: June through August take 16% of the annual total and December through February 28%, with neither reaching the 35% that would mark a distinct wet season. Snettisham Pwr Plt has no dry season to plan around, though it does carry a 30.4°F seasonal spread.
The gap between the wettest and driest month still matters: October averages 28.9" and June 6.8". The three wettest months together take 41% 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 Snettisham Pwr Plt, it arrives in quantity
189.7" of precipitation falls across only about 231 wet days here, averaging 0.82 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 231 a year, 63% of all days
- Average depth per wet day
- 0.82 inches

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.

Data-derived climate profile
How Snettisham Pwr Plt's climate pattern fits together
heating led · wet · mid swing
Snettisham Pwr Plt's energy balance leans toward cold weather: 8,731 annual heating degree days against 5 for cooling. Its 30.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Snettisham Pwr Plt's frost-free season lasts about 163 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 Snettisham Pwr Plt's middle-range seasonal profile. The measured spread is 30.4°F. The annual average is 41°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Snettisham Pwr Plt carries 189.7 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 Snettisham Pwr Plt'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 Snettisham Pwr Plt, 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 Snettisham Pwr Plt's primary station: SNETTISHAM PWR PLT (USC00508584). 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 Snettisham Pwr Plt; 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 Snettisham Pwr Plt comes from its primary NOAA station record.
