The year, day by day
Summer here tops out rather than builds: the warmest normal high is 81°F around July 28, short of 90°F on every date, while 247 dates carry a normal low at or below freezing, the coldest 3°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into May 17, then returns to freezing around September 14, covering 247 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 June 8, when 45% of years recorded at least a hundredth of an inch. The driest is September 27 at 28%. Summed across the calendar, that is about 129 wet dates a year.
The widest day
August 20 carries the biggest normal gap between afternoon and dawn, 39°F between the normal high and the normal low.

Where Tower Falls Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 247 nights a year, placing this among the most frost-prone tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 39°F, sharper than nine in ten ranked stations see.
Tower Falls earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Tower Falls spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 20%, with neither reaching the 35% that would mark a distinct wet season. Tower Falls has no dry season to plan around, though it does carry a 44.9°F seasonal spread.
The gap between the wettest and driest month still matters: June averages 2.0" and February 0.9". The three wettest months together take 32% 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.
Rain reaches Tower Falls in small, frequent amounts
Tower Falls records about 129 days with measurable precipitation a year and 16.6" in total, which works out to roughly 0.13 inches on an average wet day. Precipitation on 35% of all days, arriving that lightly, is the damp many-grey-days pattern rather than the storm-driven one.
Places in this band read as wetter than their annual totals suggest, because what people notice is the number of overcast days, not the depth in the gauge.
- Most wet days: December, about 14 of them.
- Fewest: September, about 9.
- Average depth per wet day: 0.13 inches.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Winter brings real snow to Tower Falls
Tower Falls averages 94.0 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 68 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 94.0 inches of depth.
- Days recording measurable snow: about 68 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 56% of the year's precipitation.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Tower Falls's primary station: TOWER FALLS (USC00489025). 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 Tower Falls; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
