The year, day by day
Summer here tops out rather than builds: the warmest normal high is 78°F around July 20, short of 90°F on every date, while 184 dates carry a normal low at or below freezing, the coldest 4°F near January 27.
The freezing stretch
The normal low stays at or below 32°F into April 24, then returns to freezing around October 24, covering 184 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 9 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Where Waterville Valley Nepp Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 184 nights a year, more than most ranked stations.
The normal water year runs well above the national norm at roughly 54 inches.
Waterville Valley Nepp earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Waterville Valley Nepp spreads its precipitation across the year
Neither half of the year dominates here: June through August take 27% of the annual total and December through February 23%, with neither reaching the 35% that would mark a distinct wet season. Waterville Valley Nepp has no dry season to plan around, though it does carry a wide 48.9°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 5.6" and February 3.3". The three wettest months together take 29% 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 Waterville Valley Nepp's climate pattern fits together
heating led · wet · mid swing
Waterville Valley Nepp's energy balance leans toward cold weather: 8,558 annual heating degree days against 160 for cooling. Its 48.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 136 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 Waterville Valley Nepp's middle-range seasonal profile. The measured spread is 48.9°F. The annual average is 42°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Waterville Valley Nepp carries 53.8 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 Waterville Valley 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 Waterville Valley 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 Waterville Valley Nepp's primary station: WATERVILLE VALLEY NEPP (USC00278961). 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 Waterville Valley 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 Waterville Valley Nepp comes from its primary NOAA station record.
