The year, day by day
Lewisburg Exp Stn works both ends of the calendar. Normal highs climb to 91°F by July 24 and hold at or above 90°F on 64 dates, then normal lows drop to freezing or below on 83 dates, bottoming at 27°F around January 18.
When the heat sits
Normal highs reach 90°F from June 26 through August 28, covering 64 dates. The broader mild season, normal highs of 70°F or more, runs April 8 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 24, then returns to freezing around December 4, covering 83 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 July 5, when 37% of years recorded at least a hundredth of an inch. The driest is September 13 at 25%. Summed across the calendar, that is about 115 wet dates a year.
The widest day
October 10 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Where Lewisburg Exp Stn Stands Nationally
This is one of the wettest normals climates ranked: about 56 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 64 days a year, more than four out of five ranked stations record.
Lewisburg Exp Stn earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Lewisburg Exp Stn 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 27%, with neither reaching the 35% that would mark a distinct wet season. Lewisburg Exp Stn has no dry season to plan around, though it does carry a 40.5°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 5.7" and October 3.7". 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 Lewisburg Exp Stn, it arrives in quantity
56.1" of precipitation falls across only about 115 wet days here, averaging 0.49 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 115 a year, 32% of all days
- Average depth per wet day
- 0.49 inches
- Most wet days
- July, about 11
- Fewest wet days
- September, about 7
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 Lewisburg Exp Stn, but rarely amounts to much
The normals record 0.9 inches of snow a year here, most likely in February. 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 2 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 Lewisburg Exp Stn's climate pattern fits together
heating led · wet · mid swing
Lewisburg Exp Stn's energy balance leans toward cold weather: 3,714 annual heating degree days against 1,568 for cooling. Its 40.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Lewisburg Exp Stn's frost-free season lasts about 191 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 Lewisburg Exp Stn's middle-range seasonal profile. The measured spread is 40.5°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, Lewisburg Exp Stn carries 56.1 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 0.9 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 Lewisburg Exp Stn'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 Lewisburg Exp Stn, not an official NOAA class or a year-ahead forecast.

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 Lewisburg Exp Stn; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
