The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around July 12, short of 90°F on every date, while 133 dates carry a normal low at or below freezing, the coldest 21°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into March 26, then returns to freezing around November 15, covering 133 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 January 22, when 53% of years recorded at least a hundredth of an inch. The driest is September 13 at 32%. Summed across the calendar, that is about 161 wet dates a year.
The widest day
April 17 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Tygart Dam spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Tygart Dam has no dry season to plan around, though it does carry a 41.3°F seasonal spread.
The gap between the wettest and driest month still matters: July averages 5.5" and November 3.1". The three wettest months together take 31% 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.
How Tygart Dam's precipitation splits across the calendar
About 161 days a year record measurable precipitation here, carrying 48.6" between them, or roughly 0.30 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Winter brings real snow to Tygart Dam
Tygart Dam averages 25.5 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 21 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 25.5 inches of depth.
- Days recording measurable snow: about 21 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 5% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Tygart Dam
heating led · wet · mid swing
Tygart Dam's energy balance leans toward cold weather: 5,493 annual heating degree days against 600 for cooling. Its 41.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Tygart Dam's frost-free season lasts about 179 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
-

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 Tygart Dam; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
