The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 7, short of 90°F on every date, while 109 dates carry a normal low at or below freezing, the coldest 25°F near January 19.
The freezing stretch
The normal low stays at or below 32°F into March 6, then returns to freezing around November 19, covering 109 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 July 5, when 40% of years recorded at least a hundredth of an inch. The driest is September 16 at 26%. Summed across the calendar, that is about 128 wet dates a year.
The widest day
April 14 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Where Newcomb Stands Nationally
The normal water year runs well above the national norm at roughly 55 inches.
Newcomb earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Newcomb 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 27%, with neither reaching the 35% that would mark a distinct wet season. Newcomb has no dry season to plan around, though it does carry a 39.7°F seasonal spread.
The gap between the wettest and driest month still matters: July averages 5.8" and October 2.8". 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.
When it rains in Newcomb, it arrives in quantity
54.6" of precipitation falls across only about 128 wet days here, averaging 0.43 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 128 a year, 35% of all days
- Average depth per wet day
- 0.43 inches
- Most wet days
- July, about 13
- Fewest wet days

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 Newcomb's climate pattern fits together
heating led · wet · mid swing
Newcomb's energy balance leans toward cold weather: 4,334 annual heating degree days against 1,074 for cooling. Its 39.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Newcomb's frost-free season lasts about 189 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 Newcomb's middle-range seasonal profile. The measured spread is 39.7°F. The annual average is 56°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Newcomb carries 54.6 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 Newcomb'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 Newcomb, 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 Newcomb's primary station: NEWCOMB (USC00406493). 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 Newcomb; 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 Newcomb comes from its primary NOAA station record.
