The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around July 10, short of 90°F on every date, while 152 dates carry a normal low at or below freezing, the coldest 10°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into April 6, then returns to freezing around November 7, covering 152 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 May 28, when 41% of years recorded at least a hundredth of an inch. The driest is January 19 at 22%. Summed across the calendar, that is about 114 wet dates a year.
The widest day
May 3 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Fond Du Lac County runs a summer-peaked wet season
39% of Fond Du Lac County's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is June at 4.1", on a wide 52.4°F gap between its warmest and coldest month. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: June, August, July, taking 39% of the annual total between them.
- Driest month: February at 0.7".
- Winter share: 8% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
How Fond Du Lac County's precipitation splits across the calendar
About 114 days a year record measurable precipitation here, carrying 28.4" 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.

Data-derived climate profile
How Fond Du Lac County's climate pattern fits together
heating led · moderate · mid swing
Fond Du Lac County's energy balance leans toward cold weather: 7,275 annual heating degree days against 583 for cooling. Its 52.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Fond Du Lac County's frost-free season lasts about 162 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Fond Du Lac County's middle-range seasonal profile. The measured spread is 52.4°F. The annual average is 47°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Fond Du Lac County's 28.4 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Fond Du Lac County's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Fond Du Lac County, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Fond Du Lac County's primary station: FOND DU LAC CO AP (USW00004840). 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 Fond Du Lac County; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Fond Du Lac County comes from its primary NOAA station record.
