The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around July 26, short of 90°F on every date, while 57 dates carry a normal low at or below freezing, the coldest 29°F near January 18.
The freezing stretch
The normal low stays at or below 32°F into February 14, then returns to freezing around December 20, covering 57 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 June 26, when 41% of years recorded at least a hundredth of an inch. The driest is September 30 at 26%. Summed across the calendar, that is about 132 wet dates a year.
The widest day
April 6 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Where Oak Ridge Atdd Stands Nationally
This is one of the wettest normals climates ranked: about 60 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Oak Ridge Atdd earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Oak Ridge Atdd spreads its precipitation across the year
Neither half of the year dominates here: June through August take 24% of the annual total and December through February 29%, with neither reaching the 35% that would mark a distinct wet season. Oak Ridge Atdd has no dry season to plan around, though it does carry a 39.6°F seasonal spread.
The gap between the wettest and driest month still matters: February averages 5.9" and October 3.3". 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.
When it rains in Oak Ridge Atdd, it arrives in quantity
59.7" of precipitation falls across only about 132 wet days here, averaging 0.45 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 132 a year, 36% of all days
- Average depth per wet day
- 0.45 inches
- Most wet days
- July, 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 Oak Ridge Atdd, but rarely amounts to much
The normals record 4.4 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 3 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 Oak Ridge Atdd's climate pattern fits together
heating led · wet · mid swing
Oak Ridge Atdd's energy balance leans toward cold weather: 3,732 annual heating degree days against 1,414 for cooling. Its 39.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Oak Ridge Atdd's frost-free season lasts about 210 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 Oak Ridge Atdd's middle-range seasonal profile. The measured spread is 39.6°F. The annual average is 59°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Oak Ridge Atdd carries 59.7 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 4.4 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 Oak Ridge Atdd'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 Oak Ridge Atdd, 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 Oak Ridge Atdd's primary station: OAK RIDGE ATDD (USW00003841). 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 Oak Ridge Atdd; 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 Oak Ridge Atdd comes from its primary NOAA station record.
