The year, day by day
Franklin Sewage Plt works both ends of the calendar. Normal highs climb to 91°F by July 17 and hold at or above 90°F on 53 dates, then normal lows drop to freezing or below on 67 dates, bottoming at 28°F around January 17.
When the heat sits
Normal highs reach 90°F from June 30 through August 21, covering 53 dates. The broader mild season, normal highs of 70°F or more, runs April 9 to October 25.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into February 19, then returns to freezing around December 15, covering 67 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 March 11, when 41% of years recorded at least a hundredth of an inch. The driest is September 15 at 28%. Summed across the calendar, that is about 130 wet dates a year.
The widest day
October 16 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Franklin Sewage Plt spreads its precipitation across the year
Neither half of the year dominates here: June through August take 23% of the annual total and December through February 26%, with neither reaching the 35% that would mark a distinct wet season. Franklin Sewage Plt has no dry season to plan around, though it does carry a 40.8°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 5.4" and October 3.5". 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 Franklin Sewage Plt, it arrives in quantity
53.8" of precipitation falls across only about 130 wet days here, averaging 0.41 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 130 a year, 36% of all days
- Average depth per wet day
- 0.41 inches
- Most wet days
- March, about 13
- Fewest wet days
- September, 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.
Snow reaches Franklin Sewage Plt, but rarely amounts to much
The normals record 1.7 inches of snow a year here, most likely in January. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 1 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Franklin Sewage Plt's climate pattern fits together
heating led · wet · mid swing
Franklin Sewage Plt's energy balance leans toward cold weather: 3,601 annual heating degree days against 1,686 for cooling. Its 40.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Franklin Sewage Plt's frost-free season lasts about 211 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 Franklin Sewage Plt's middle-range seasonal profile. The measured spread is 40.8°F. The annual average is 60°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Franklin Sewage Plt carries 53.8 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 1.7 inches. 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 Franklin Sewage Plt'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 Franklin Sewage Plt, not an official NOAA class or a year-ahead forecast.

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