The year, day by day
Summer here tops out rather than builds: the warmest normal high is 90°F around August 3, short of 90°F on every date, while 82 dates carry a normal low at or below freezing, the coldest 27°F near January 17.
The freezing stretch
The normal low stays at or below 32°F into February 25, then returns to freezing around December 6, covering 82 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 May 3, when 36% of years recorded at least a hundredth of an inch. The driest is September 27 at 22%. Summed across the calendar, that is about 106 wet dates a year.
The widest day
April 8 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Clarksville 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 25%, with neither reaching the 35% that would mark a distinct wet season. Clarksville has no dry season to plan around, though it does carry a 41.5°F seasonal spread.
The gap between the wettest and driest month still matters: March averages 5.7" and August 3.3". 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.
When it rains in Clarksville, it arrives in quantity
53.3" of precipitation falls across only about 106 wet days here, averaging 0.50 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 106 a year, 29% of all days
- Average depth per wet day
- 0.50 inches
- Most wet days
- February, about 11
- Fewest wet days

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.

Data-derived climate profile
How Clarksville's climate pattern fits together
heating led · wet · mid swing
Clarksville's energy balance leans toward cold weather: 3,916 annual heating degree days against 1,484 for cooling. Its 41.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Clarksville's frost-free season lasts about 203 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 Clarksville's middle-range seasonal profile. The measured spread is 41.5°F. The annual average is 58°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Clarksville carries 53.3 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 Clarksville'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 Clarksville, not an official NOAA class or a year-ahead forecast.
