The year, day by day
Lacrosse works both ends of the calendar. Normal highs climb to 92°F by July 25 and hold at or above 90°F on 30 dates, then normal lows drop to freezing or below on 139 dates, bottoming at 24°F around December 19.
When the heat sits
Normal highs reach 90°F from July 14 through August 12, covering 30 dates. The broader mild season, normal highs of 70°F or more, runs May 10 to October 3.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into March 22, then returns to freezing around November 5, covering 139 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 December 12, when 47% of years recorded at least a hundredth of an inch. The driest is August 14 at 9%. Summed across the calendar, that is about 106 wet dates a year.
The widest day
July 25 carries the biggest normal gap between afternoon and dawn, 38°F between the normal high and the normal low.

Where Lacrosse Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 38°F, sharper than nine in ten ranked stations see.
A drier-than-most normal water year — around 15 inches, below what four out of five ranked stations collect.
Lacrosse earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Lacrosse's wet season runs through the cold months
December, January and February carry 38% of the year's precipitation here, while June through August contribute 11%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 40.1°F seasonal spread.
- Wettest month
- December, 2.4"
- Driest month
- July, 0.3"
- Wettest three months
- December, January, November (42% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
Lacrosse is dry, and what does fall arrives gently
Only about 106 days a year record measurable precipitation here, 29% of the calendar, and they carry 15.1" between them. At roughly 0.14 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is December at about 15 wet days; the driest is August at about 3.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.
Winter brings real snow to Lacrosse
Lacrosse averages 17.1 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 14 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: 17.1 inches of depth.
- Days recording measurable snow: about 14 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.

Snow and freeze rhythm
When cold and snow define Lacrosse
heating led · dry · mid swing
Lacrosse's energy balance leans toward cold weather: 5,915 annual heating degree days against 506 for cooling. Its 40.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 136 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
