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 131 dates carry a normal low at or below freezing, the coldest 19°F near January 29.
The freezing stretch
The normal low stays at or below 32°F into April 1, then returns to freezing around November 23, covering 131 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 10, when 52% of years recorded at least a hundredth of an inch. The driest is August 30 at 29%. Summed across the calendar, that is about 143 wet dates a year.
The widest day
May 17 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Muskegon County 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 20%, with neither reaching the 35% that would mark a distinct wet season. Muskegon County has no dry season to plan around, though it does carry a wide 45.3°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 3.8" and February 2.1". The three wettest months together take 30% 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 Muskegon County's precipitation splits across the calendar
About 143 days a year record measurable precipitation here, carrying 35.1" between them, or roughly 0.25 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 Muskegon County
Muskegon County averages 87.2 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 48 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: 87.2 inches of depth.
- Days recording measurable snow: about 48 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 25% 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.

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