The year, day by day
Summer here tops out rather than builds: the warmest normal high is 60°F around July 6, short of 90°F on every date, while 207 dates carry a normal low at or below freezing, the coldest 14°F near January 12.
The freezing stretch
The normal low stays at or below 32°F into April 28, then returns to freezing around October 5, covering 207 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 September 13, when 58% of years recorded at least a hundredth of an inch. The driest is May 15 at 31%. Summed across the calendar, that is about 162 wet dates a year.
The widest day
June 6 carries the biggest normal gap between afternoon and dawn, 15°F between the normal high and the normal low.

Where Glen Alps Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 207 nights a year, placing this among the most frost-prone tenth of ranked stations.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 15°F.

Glen Alps 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 23%, with neither reaching the 35% that would mark a distinct wet season. Glen Alps has no dry season to plan around, though it does carry a 33.4°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 4.3" and May 0.8". The three wettest months together take 41% 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.
Rain reaches Glen Alps in small, frequent amounts
Glen Alps records about 162 days with measurable precipitation a year and 26.0" in total, which works out to roughly 0.16 inches on an average wet day. Precipitation on 44% of all days, arriving that lightly, is the damp many-grey-days pattern rather than the storm-driven one.
Places in this band read as wetter than their annual totals suggest, because what people notice is the number of overcast days, not the depth in the gauge.
- Most wet days: September, about 18 of them.
- Fewest: May, about 10.
- Average depth per wet day: 0.16 inches.
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 Glen Alps
Glen Alps averages 161.9 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 54 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: 161.9 inches of depth.
- Days recording measurable snow: about 54 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 62% 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 Glen Alps
heating led · moderate · mid swing
Glen Alps's energy balance leans toward cold weather: 11,088 annual heating degree days against 1 for cooling. Its 33.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 128 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.

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