The year, day by day
Summer here tops out rather than builds: the warmest normal high is 62°F around July 30, short of 90°F on every date, while 92 dates carry a normal low at or below freezing, the coldest 31°F near January 9.
The freezing stretch
The normal low stays at or below 32°F into March 20, then returns to freezing around December 20, covering 92 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 November 3, when 81% of years recorded at least a hundredth of an inch. The driest is June 29 at 46%. Summed across the calendar, that is about 240 wet dates a year.
The widest day
May 20 carries the biggest normal gap between afternoon and dawn, 13°F between the normal high and the normal low.

Where Little Port Walter Stands Nationally
This is one of the wettest normals climates ranked: about 246 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 13°F.
Little Port Walter earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Little Port Walter spreads its precipitation across the year
Neither half of the year dominates here: June through August take 14% of the annual total and December through February 32%, with neither reaching the 35% that would mark a distinct wet season. Little Port Walter has no dry season to plan around, though it does carry an unusually narrow 21.5°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 32.1" and June 7.8". The three wettest months together take 38% 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 Little Port Walter, it arrives in quantity
245.7" of precipitation falls across only about 239 wet days here, averaging 1.03 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 239 a year, 66% of all days
- Average depth per wet day
- 1.03 inches
- Most wet days
- December, about 25
- Fewest wet days
- June, about 15
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.
Winter brings real snow to Little Port Walter
Little Port Walter averages 101.8 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 33 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 101.8 inches of depth.
- Days recording measurable snow: about 33 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 4% of the year's precipitation.

Snow and freeze rhythm
When cold and snow define Little Port Walter
heating led · wet · low swing
Heating is the larger measured load in Little Port Walter, at 7,600 degree days versus 1 for cooling. Unlike a strongly continental record, however, its 21.5°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Little Port Walter's frost-free season lasts about 193 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

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 Little Port Walter; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
