The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 11, short of 90°F on every date, while 113 dates carry a normal low at or below freezing, the coldest 23°F near January 24.
The freezing stretch
The normal low stays at or below 32°F into March 18, then returns to freezing around November 27, covering 113 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 April 22, when 37% of years recorded at least a hundredth of an inch. The driest is September 4 at 26%. Summed across the calendar, that is about 115 wet dates a year.
The widest day
April 24 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Millville Muni spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Millville Muni has no dry season to plan around, though it does carry a 43.2°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 4.6" and February 2.6". The three wettest months together take 30% 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 Millville Muni, it arrives in quantity
43.4" of precipitation falls across only about 115 wet days here, averaging 0.38 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 115 a year, 31% of all days
- Average depth per wet day
- 0.38 inches
- Most wet days
- April, about 11
- Fewest wet days
- November, about 8
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 Millville Muni's climate pattern fits together
heating led · moderate · mid swing
Millville Muni's energy balance leans toward cold weather: 4,934 annual heating degree days against 1,050 for cooling. Its 43.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Millville Muni's frost-free season lasts about 182 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 Millville Muni's middle-range seasonal profile. The measured spread is 43.2°F. The annual average is 54°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Millville Muni's 43.4 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Millville Muni'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 Millville Muni, 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 Millville Muni's primary station: MILLVILLE MUNI AP (USW00013735). 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 Millville Muni; 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 Millville Muni comes from its primary NOAA station record.
