The year, day by day
Summer here tops out rather than builds: the warmest normal high is 81°F around July 19, short of 90°F on every date, while 162 dates carry a normal low at or below freezing, the coldest 12°F near January 20.
The freezing stretch
The normal low stays at or below 32°F into April 11, then returns to freezing around November 2, covering 162 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.
The widest day
September 4 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Walpole 2S Nepp spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 21%, with neither reaching the 35% that would mark a distinct wet season. Walpole 2S Nepp has no dry season to plan around, though it does carry a wide 47.8°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: June averages 5.1" and February 3.0". The three wettest months together take 31% 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.

Data-derived climate profile
How Walpole 2S Nepp's climate pattern fits together
heating led · wet · mid swing
Walpole 2S Nepp's energy balance leans toward cold weather: 7,259 annual heating degree days against 383 for cooling. Its 47.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 148 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and January mark the typical warm and cold ends of the calendar in Walpole 2S Nepp's middle-range seasonal profile. The measured spread is 47.8°F. The annual average is 46°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Walpole 2S Nepp carries 47.0 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 Walpole 2S Nepp'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 Walpole 2S Nepp, 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 Walpole 2S Nepp's primary station: WALPOLE 2S NEPP (USC00278856). 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 Walpole 2S Nepp; 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 Walpole 2S Nepp comes from its primary NOAA station record.
