The year, day by day

Greers Ferry Dam works both ends of the calendar. Normal highs climb to 92°F by August 1 and hold at or above 90°F on 50 dates, then normal lows drop to freezing or below on 72 dates, bottoming at 27°F around January 13.

When the heat sits

Normal highs reach 90°F from July 5 through August 23, covering 50 dates. The broader mild season, normal highs of 70°F or more, runs April 10 to October 24.

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 20, then returns to freezing around December 11, covering 72 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 33% of years recorded at least a hundredth of an inch. The driest is September 28 at 22%. Summed across the calendar, that is about 100 wet dates a year.

The widest day

April 11 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Greers Ferry Dam spreads its precipitation across the year

Neither half of the year dominates here: June through August take 22% of the annual total and December through February 24%, with neither reaching the 35% that would mark a distinct wet season. Greers Ferry Dam has no dry season to plan around, though it does carry a 42.1°F seasonal spread.

The gap between the wettest and driest month still matters: May averages 5.7" and September 3.6". 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 Greers Ferry Dam, it arrives in quantity

53.4" of precipitation falls across only about 100 wet days here, averaging 0.53 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

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 Greers Ferry Dam, but rarely amounts to much

The normals record 2.6 inches of snow a year here, most likely in March. 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 Greers Ferry Dam's climate pattern fits together

heating led · wet · mid swing

Greers Ferry Dam's energy balance leans toward cold weather: 3,577 annual heating degree days against 1,725 for cooling. Its 42.1°F seasonal range still makes the monthly rows more useful than the annual average alone.

Greers Ferry Dam's frost-free season lasts about 220 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 Greers Ferry Dam's middle-range seasonal profile. The measured spread is 42.1°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, Greers Ferry Dam carries 53.4 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 2.6 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 Greers Ferry Dam'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 Greers Ferry Dam, not an official NOAA class or a year-ahead forecast.

Questions about Greers Ferry Dam's climate

How much rain does Greers Ferry Dam get?
Greers Ferry Dam receives 53.4 inches of precipitation, including 2.6 inches of snow. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Greers Ferry Dam get?
Greers Ferry Dam averages about 54 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Greers Ferry Dam?
Greers Ferry Dam has 3,577 heating degree days and 1,725 cooling degree days annually, a heating-dominated climate. Degree-day definitions: reading weather data.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Greers Ferry Dam's primary station: GREERS FERRY DAM (USC00032978). 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 Greers Ferry Dam; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
