The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 10, short of 90°F on every date, while 141 dates carry a normal low at or below freezing, the coldest 9°F near January 22.
The freezing stretch
The normal low stays at or below 32°F into March 28, then returns to freezing around November 9, covering 141 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 6, when 39% of years recorded at least a hundredth of an inch. The driest is November 3 at 27%. Summed across the calendar, that is about 112 wet dates a year.
The widest day
April 27 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Guttenberg L&d runs a summer-peaked wet season
38% of Guttenberg L&d'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 5.7", on a wide 54.8°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, July, May, taking 41% of the annual total between them.
- Driest month: February at 1.2".
- Winter share: 11% 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 Guttenberg L&d's precipitation splits across the calendar
About 112 days a year record measurable precipitation here, carrying 37.3" between them, or roughly 0.33 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 Guttenberg L&d
Guttenberg L&d averages 34.4 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 18 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: 34.4 inches of depth.
- Days recording measurable snow: about 18 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 9% 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.

heating led · moderate · mid swing
Guttenberg L&d's energy balance leans toward cold weather: 6,796 annual heating degree days against 832 for cooling. Its 54.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Guttenberg L&d's frost-free season lasts about 180 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 Guttenberg L&d; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
