The year, day by day
Summer here tops out rather than builds: the warmest normal high is 88°F around July 16, short of 90°F on every date, while 108 dates carry a normal low at or below freezing, the coldest 25°F near January 20.
The freezing stretch
The normal low stays at or below 32°F into March 6, then returns to freezing around November 20, covering 108 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 February 27, when 44% of years recorded at least a hundredth of an inch. The driest is September 13 at 29%. Summed across the calendar, that is about 141 wet dates a year.
The widest day
October 28 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Greeneville Exp Stn 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 25%, with neither reaching the 35% that would mark a distinct wet season. Greeneville Exp Stn has no dry season to plan around, though it does carry a 39.5°F seasonal spread.
The gap between the wettest and driest month still matters: July averages 5.0" and October 2.7". 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.
How Greeneville Exp Stn's precipitation splits across the calendar
About 140 days a year record measurable precipitation here, carrying 46.4" between them, or roughly 0.33 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
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.
Snow reaches Greeneville Exp Stn, but rarely amounts to much
The normals record 7.7 inches of snow a year here, most likely in February. 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 6 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 Greeneville Exp Stn's climate pattern fits together
heating led · wet · mid swing
Greeneville Exp Stn's energy balance leans toward cold weather: 4,165 annual heating degree days against 1,182 for cooling. Its 39.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Greeneville Exp Stn's frost-free season lasts about 185 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 Greeneville Exp Stn's middle-range seasonal profile. The measured spread is 39.5°F. The annual average is 57°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Greeneville Exp Stn carries 46.4 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 7.7 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 Greeneville Exp Stn'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 Greeneville Exp Stn, 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 Greeneville Exp Stn's primary station: GREENEVILLE EXP STN (USC00403679). 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 Greeneville Exp Stn; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
