Snowmaking weather normally reaches Wausau around Oct 29, 59 days away.
That is the whole estimate, and it is the weather rather than a resort. No opening date for any resort here is on file yet, so there is nothing to project from. The chart and the tiles below are the same ones the Minnesota page runs on, taken at Lake Geneva, Madison and Wausau instead of at resorts. The curve is Madison.

When the guns can run
Snow guns need a wet-bulb temperature under 28°F. The mean at Madison
does not get there until Dec 1, but the first workable window normally
arrives on Nov 2. Resorts open on those early cold snaps rather than on
the average.

Want resort specific info? We need help!
We need somebody to help find opening dates, closing dates, and where the two can be
told apart, the pre-season opening versus the full one. That mostly means trolling
their Facebook feeds by hand. Sometimes the websites have it.
Minnesota shows what a region looks like once it is filled in.
If you know Wisconsin resorts, or want to take on the whole state, that is the whole job.
Email eazydp@gmail.com. Dates for resorts already
listed are just as welcome.
