When does it first snow in La Crosse, WI?

At La Crosse, the typical date of the first measurable snowfall (0.1 inch or more in a day) is Nov 12. That is the median over the last 30 snow seasons: half of seasons saw it earlier, half later. In about 1 season in 10 it came by Oct 23, and in 1 in 10 not until Dec 3 or later. The earliest was Oct 1 (1999-00) and the latest Dec 23 (2001-02). A first snowfall of at least 1 inch in a single day typically arrives around Dec 3, and 100% of seasons had one. The first freeze of fall (a low of 32°F or colder) typically comes around Oct 15, and the last freeze of spring around Apr 26.

This season so far (2026-27, data through Oct 16, 2026): no measurable snow recorded yet; no 32°F freeze recorded yet at this station. Compare with the typical dates above. This is observed data and can lag by a day or two, and it is not a forecast.

The median stretch between the last spring freeze and the first fall freeze (the freeze-free season) was about 174 days.
