The year, day by day
Greenbrier works both ends of the calendar. Normal highs climb to 92°F by August 2 and hold at or above 90°F on 67 dates, then normal lows drop to freezing or below on 82 dates, bottoming at 28°F around January 26.
When the heat sits
Normal highs reach 90°F from June 24 through August 29, covering 67 dates. The broader mild season, normal highs of 70°F or more, runs April 5 to October 25.
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 23, then returns to freezing around December 4, 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 4, when 32% of years recorded at least a hundredth of an inch. The driest is July 10 at 20%. Summed across the calendar, that is about 93 wet dates a year.
The widest day
October 8 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Where Greenbrier Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 67 days a year, more than four out of five ranked stations record.
The normal water year runs well above the national norm at roughly 51 inches.
Greenbrier earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Greenbrier 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 22%, with neither reaching the 35% that would mark a distinct wet season. Greenbrier has no dry season to plan around, though it does carry a 41.4°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 5.5" and January 3.2". 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 Greenbrier, it arrives in quantity
50.5" of precipitation falls across only about 93 wet days here, averaging 0.54 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 93 a year, 26% of all days
- Average depth per wet day
- 0.54 inches
- Most wet days
- May, about 10

- July, about 6
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 Greenbrier's climate pattern fits together
heating led · wet · mid swing
Greenbrier's energy balance leans toward cold weather: 3,575 annual heating degree days against 1,697 for cooling. Its 41.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Greenbrier's frost-free season lasts about 199 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 Greenbrier's middle-range seasonal profile. The measured spread is 41.4°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, Greenbrier carries 50.5 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 Greenbrier'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 Greenbrier, not an official NOAA class or a year-ahead forecast.
