Before you book
This bet missed 6 of the last 10.
3 of the last 10 came in under 8″ — a bust, under a third of the bet.
Odds count natural snowfall only. At snowmaking-dependent resorts, early-season cover can be fine in a low-natural-snow year.
The season, window by window
The bet: 12″ of new snow per week, scaled to each window. Counted from real seasons — how our odds work.

The middle season — median new snow per window, counted from the last 20 winters. A picture of timing, not a forecast. Snow is streaky; hover any window for the usual range.

Field notes
Maine's eight-peak sprawl — one of the biggest snowmaking arsenals in New England painting terrain across a long ridgeline, with the Oz and Jordan Bowl glades adding texture. Consistent product over dramatic terrain.
Ikon. Boston is far enough away that weekend crowds run gentler than New Hampshire's. The eight-peak layout means long traverses — pick a zone per day. Bethel is the modest town base.

These are historical odds from the last 20 winters — not a forecast. Inside 16 days of a trip, a forecast is the better instrument; beyond that, counting real seasons is the honest play. Every number on this page is quoted under methodology v1.2.0, the same math we grade ourselves against in public.
