The year, day by day
John H Kerr Dam works both ends of the calendar. Normal highs climb to 92°F by July 10 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 19.
When the heat sits
Normal highs reach 90°F from June 24 through August 15, covering 53 dates. The broader mild season, normal highs of 70°F or more, runs April 9 to October 26.
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 21, then returns to freezing around December 17, 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 May 19, when 35% of years recorded at least a hundredth of an inch. The driest is October 24 at 25%. Summed across the calendar, that is about 112 wet dates a year.
The widest day
October 26 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

John H Kerr Dam spreads its precipitation across the year
Neither half of the year dominates here: June through August take 31% of the annual total and December through February 21%, with neither reaching the 35% that would mark a distinct wet season. John H Kerr Dam 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: July averages 4.9" and February 2.5". The three wettest months together take 31% 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 John H Kerr Dam, it arrives in quantity
43.5" of precipitation falls across only about 112 wet days here, averaging 0.39 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 112 a year, 31% of all days
- Average depth per wet day

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 John H Kerr Dam's climate pattern fits together
mixed demand · moderate · mid swing
July and January mark the typical warm and cold ends of the calendar in John H Kerr Dam's middle-range seasonal profile. The measured spread is 41.5°F. The annual average is 60°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in John H Kerr Dam's normal, at 3,504 and 1,825 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
A roughly 210-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.
John H Kerr Dam's 43.5 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from John H Kerr Dam's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like John H Kerr Dam, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from John H Kerr Dam's primary station: JOHN H KERR DAM (USC00444414). 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 John H Kerr Dam; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for John H Kerr Dam comes from its primary NOAA station record.
