The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 8, short of 90°F on every date, while 132 dates carry a normal low at or below freezing, the coldest 17°F near January 25.
The freezing stretch
The normal low stays at or below 32°F into March 23, then returns to freezing around November 13, covering 132 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 28, when 41% of years recorded at least a hundredth of an inch. The driest is September 5 at 21%. Summed across the calendar, that is about 115 wet dates a year.
The widest day
October 1 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Franklin Wwtp 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. Franklin Wwtp has no dry season to plan around, though it does carry a wide 47.4°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 5.3" and February 2.5". The three wettest months together take 34% 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 Franklin Wwtp, it arrives in quantity
45.4" of precipitation falls across only about 114 wet days here, averaging 0.40 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 114 a year, 31% of all days
- Average depth per wet day
- 0.40 inches
- Most wet days
- April, about 12
- Fewest wet days
- September, about 7
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.
Winter brings real snow to Franklin Wwtp
Franklin Wwtp averages 16.9 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 10 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: 16.9 inches of depth.
- Days recording measurable snow: about 10 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 4% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Franklin Wwtp
heating led · wet · mid swing
Franklin Wwtp's energy balance leans toward cold weather: 5,752 annual heating degree days against 897 for cooling. Its 47.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Franklin Wwtp'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.

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 Franklin Wwtp; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
