The year, day by day
Lake Greenwood works both ends of the calendar. Normal highs climb to 91°F by July 19 and hold at or above 90°F on 33 dates, then normal lows drop to freezing or below on 60 dates, bottoming at 29°F around January 8.
When the heat sits
Normal highs reach 90°F from July 6 through August 7, covering 33 dates. The broader mild season, normal highs of 70°F or more, runs March 31 to October 27.
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 13, then returns to freezing around December 16, covering 60 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.
The widest day
March 27 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Monthly Precipitation
Average monthly rainfall
Lake Greenwood spreads its precipitation across the year
Neither half of the year dominates here: June through August take 27% of the annual total and December through February 26%, with neither reaching the 35% that would mark a distinct wet season. Lake Greenwood has no dry season to plan around, though it does carry a 38°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 4.6" and October 3.3". The three wettest months together take 29% 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.

Data-derived climate profile
How Lake Greenwood's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Lake Greenwood averages 47.3 inches of precipitation a year. Snowfall is not added to the interpretation because its annual value is missing. The monthly table supplies the seasonal distribution hidden by that annual total.
July and January mark the typical warm and cold ends of the calendar in Lake Greenwood's middle-range seasonal profile. The measured spread is 38.0°F. The annual average is 61°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Lake Greenwood's normal, at 3,187 and 1,691 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 217-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.
These labels group NOAA 1991-2020 normals from Lake Greenwood'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 Lake Greenwood, 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 Lake Greenwood's primary station: LAKE GREENWOOD (USC00384896). 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 Lake Greenwood; 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 Lake Greenwood comes from its primary NOAA station record.
