The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around July 9, short of 90°F on every date, while 146 dates carry a normal low at or below freezing, the coldest 15°F near January 24.
The freezing stretch
The normal low stays at or below 32°F into April 4, then returns to freezing around November 11, covering 146 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 9, when 47% of years recorded at least a hundredth of an inch. The driest is July 12 at 32%. Summed across the calendar, that is about 145 wet dates a year.
The widest day
September 21 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Coldwater St School spreads its precipitation across the year
Neither half of the year dominates here: June through August take 31% of the annual total and December through February 18%, with neither reaching the 35% that would mark a distinct wet season. Coldwater St School has no dry season to plan around, though it does carry a wide 47.5°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: August averages 4.4" and March 2.2". The three wettest months together take 33% 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 Coldwater St School's precipitation splits across the calendar
About 145 days a year record measurable precipitation here, carrying 39.1" between them, or roughly 0.27 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 Coldwater St School
Coldwater St School averages 42.7 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 28 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: 42.7 inches of depth.
- Days recording measurable snow: about 28 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 11% 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.

When cold and snow define Coldwater St School
heating led · moderate · mid swing
Coldwater St School's energy balance leans toward cold weather: 6,704 annual heating degree days against 567 for cooling. Its 47.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Coldwater St School's frost-free season lasts about 164 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 Coldwater St School; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
