The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around August 9, short of 90°F on every date, while 86 dates carry a normal low at or below freezing, the coldest 26°F near January 20.
The freezing stretch
The normal low stays at or below 32°F into February 26, then returns to freezing around December 3, covering 86 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 February 11, when 46% of years recorded at least a hundredth of an inch. The driest is September 14 at 28%. Summed across the calendar, that is about 142 wet dates a year.
The widest day
April 12 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Byrdstown spreads its precipitation across the year
Neither half of the year dominates here: June through August take 26% of the annual total and December through February 27%, with neither reaching the 35% that would mark a distinct wet season. Byrdstown has no dry season to plan around, though it does carry a 39.4°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 5.3" 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.
When it rains in Byrdstown, it arrives in quantity
54.6" of precipitation falls across only about 140 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.
- Days with measurable precipitation
- about 140 a year, 38% of all days
- Average depth per wet day
- 0.39 inches
- Most wet days
- January, about 14
- Fewest wet days

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 Byrdstown's climate pattern fits together
heating led · wet · mid swing
Byrdstown's energy balance leans toward cold weather: 4,125 annual heating degree days against 1,150 for cooling. Its 39.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Byrdstown's frost-free season lasts about 196 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 Byrdstown's middle-range seasonal profile. The measured spread is 39.4°F. The annual average is 57°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Byrdstown carries 54.6 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 Byrdstown'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 Byrdstown, not an official NOAA class or a year-ahead forecast.
