The year, day by day
Summer here tops out rather than builds: the warmest normal high is 75°F around July 31, short of 90°F on every date, while 163 dates carry a normal low at or below freezing, the coldest 12°F near January 31.
The freezing stretch
The normal low stays at or below 32°F into April 18, then returns to freezing around November 8, covering 163 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 October 20, when 49% of years recorded at least a hundredth of an inch. The driest is March 9 at 31%. Summed across the calendar, that is about 138 wet dates a year.
The widest day
August 28 carries the biggest normal gap between afternoon and dawn, 17°F between the normal high and the normal low.

Harrisville spreads its precipitation across the year
Neither half of the year dominates here: June through August take 33% of the annual total and December through February 14%, with neither reaching the 35% that would mark a distinct wet season. Harrisville has no dry season to plan around, though it does carry a wide 45.9°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: July averages 3.4" and February 1.1". The three wettest months together take 34% 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 Harrisville's precipitation splits across the calendar
About 138 days a year record measurable precipitation here, carrying 29.1" between them, or roughly 0.21 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 Harrisville
Harrisville averages 52.4 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 36 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: 52.4 inches of depth.
- Days recording measurable snow: about 36 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 18% 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 Harrisville
heating led · moderate · mid swing
Harrisville's energy balance leans toward cold weather: 8,233 annual heating degree days against 192 for cooling. Its 45.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Harrisville's frost-free season lasts about 161 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
