The year, day by day
Summer here tops out rather than builds: the warmest normal high is 79°F around July 16, short of 90°F on every date, while 179 dates carry a normal low at or below freezing, the coldest 4°F near January 27.
The freezing stretch
The normal low stays at or below 32°F into April 21, then returns to freezing around October 26, covering 179 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 June 8, when 47% of years recorded at least a hundredth of an inch. The driest is February 6 at 29%. Summed across the calendar, that is about 138 wet dates a year.
The widest day
May 5 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where East Hiram Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 179 nights a year, more than most ranked stations.

East Hiram spreads its precipitation across the year
Neither half of the year dominates here: June through August take 25% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. East Hiram has no dry season to plan around, though it does carry a wide 49.9°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 5.4" and February 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 East Hiram, it arrives in quantity
49.7" of precipitation falls across only about 138 wet days here, averaging 0.36 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 138 a year, 38% of all days
- Average depth per wet day
- 0.36 inches
- Most wet days
- June, about 14
- Fewest wet days
- February, about 8
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.
Winter brings real snow to East Hiram
East Hiram averages 77.9 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 29 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: 77.9 inches of depth.
- Days recording measurable snow: about 29 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 16% 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 East Hiram
heating led · wet · mid swing
East Hiram's energy balance leans toward cold weather: 8,086 annual heating degree days against 265 for cooling. Its 49.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 142 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.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from East Hiram's primary station: EAST HIRAM (USC00172238). For informational purposes only.
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 East Hiram; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
