The year, day by day
Summer here tops out rather than builds: the warmest normal high is 80°F around July 19, short of 90°F on every date, while 156 dates carry a normal low at or below freezing, the coldest 9°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into April 10, then returns to freezing around November 7, covering 156 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
May 18 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Trenton Falls Stands Nationally
The normal water year runs well above the national norm at roughly 51 inches.
Days and nights track unusually close together; the widest normal swing, about 23°F, is narrower than most stations record.
Trenton Falls earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Trenton Falls 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 22%, with neither reaching the 35% that would mark a distinct wet season. Trenton Falls has no dry season to plan around, though it does carry a wide 49°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 5.3" and February 3.4". 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 Trenton Falls's climate pattern fits together
heating led · wet · mid swing
Trenton Falls's energy balance leans toward cold weather: 7,466 annual heating degree days against 375 for cooling. Its 49.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Trenton Falls's frost-free season lasts about 162 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 Trenton Falls's middle-range seasonal profile. The measured spread is 49.0°F. The annual average is 45°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Trenton Falls carries 51.4 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 Trenton Falls'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 Trenton Falls, 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 Trenton Falls's primary station: TRENTON FALLS (USC00308578). 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 Trenton Falls; 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 Trenton Falls comes from its primary NOAA station record.
