Stowe Climate Change Profile

Overall 44

Winter Resilience Score

More climate-resilient than 84% of Eastern & Midwestern resorts · 44% of all North American resorts

#12 of 68 in the East & Midwest · #123 of 220 overall

What goes into it, compared with Eastern & Midwestern resorts:

  • Season length at +2°C 20% better than 100%
  • Rain on the snowpack at +2°C 40% better than 24%
  • Snowmaking weather at +2°C 10% better than 90%
  • Terrain orientation 30% better than 77%

* A ranking against the North American resorts we rate, not a grade out of 100: 100 = most resilient in the field, 50 = middle of the pack. Higher scores mean the resort's terrain and weather profile are more resilient in preserving winter conditions, both today and in a future of warmer temperatures.

Stowe Climate Change Takeaways

  • Rain potential: About 19% of winter precipitation falls as rain today, rising to about 31% with 2°C of warming. Ranks #5 of 68 Eastern & Midwestern resorts for rain resilience (#97 of 220 overall).
  • Season length: About 153 naturally skiable days a season today (Nov–Apr); about 134 with 2°C of warming (19 fewer).
  • Snow preservation: Terrain faces mostly east and gets about 1% more winter sun than neutral terrain. Its orientation holds snow better than 17% of Eastern & Midwestern resorts (18% of all North American resorts).
  • Base area viability: Moderate: the 2,240' base has about 143 naturally skiable days a season today, about 112 at +2°C.

Stowe Rain Resiliency Score

56

Less rain risk than 94% of Eastern & Midwestern resorts · 56% of all North American resorts

#5 of 68 in the East & Midwest · #97 of 220 overall

About 19.4% of winter precipitation falls as rain today, about 31% at +2°C.

How well Stowe's winter precipitation holds up as snow rather than rain. We rebuilt 40 winters of hourly weather at the resort's base, mid-mountain and peak, then estimated whether each hour's precipitation fell as rain or snow from temperature and humidity. To see what warming would do, we re-ran the same winters 1°C and 2°C warmer. The score is a ranking, not a grade: 100 = least rain risk in the field, 50 = middle of the pack.

The first two columns are the real observed weather record, split into two equal halves. * The +1°C and +2°C columns are stress tests: the full observed record replayed with that much warming added, so they show sensitivity to warming, not a forecast for a specific year.

Stowe Season Length

153 days

More naturally skiable days than 100% of Eastern & Midwestern resorts · 68% of all North American resorts

#1 of 68 in the East & Midwest · #69 of 220 overall

153 of 181 possible days today (Nov–Apr), about 134 at +2°C.

How many days a season Stowe has enough natural snow to ski, November through April. We simulated the snowpack day by day for 40 winters at the base, mid-mountain and peak — snow piling up, melting on warm days, and getting eaten away by rain — then ran the same winters 1°C and 2°C warmer.

Skiable by Christmas 87% → 67% of winters with a skiable base on Dec 20, today → +2°C
Rain-on-snow days 10.0 → 12.2 per season with real rain (5+ mm) falling on the snowpack — slush, then ice
Snowmaking hours 910 → 710 hours cold enough to make snow at the base, Nov–Dec
Why rain matters more than you'd think

Warmer winters don't just turn some snowfall into rain. Rain also eats away the snow that's already on the ground, in four ways:

  1. The rain itself is warm. This is the smallest effect — a soaking rain only melts a sliver of snow directly.
  2. Rainstorms bring warm, humid air. When moist air hits the snow, water condenses on the surface and releases heat. That's the main reason a single warm storm can wipe out a foot of base in a day.
  3. Rain primes the snowpack to melt. Cold snow soaks up rain and refreezes it, which warms the whole pack. Once it's soaked and at the melting point, every warm hour after that goes straight to melting.
  4. Rain wrecks the surface. Even when the base survives, rain leaves slush that freezes into ice. That's why we count rain-on-snow days separately — they hurt your ski day even when the snowpack doesn't disappear.

Our model simulates all four, using a simplified version of the snowmelt model the U.S. National Weather Service uses for river forecasting.

Natural snow only — no snowmaking or grooming, so resorts that make a lot of snow stay open longer than these numbers. “Skiable” means at least 3 inches of snow-water in the snowpack (roughly a 12–18 inch settled base). Snowfall is scaled to match Stowe's average snowfall. Melt follows the sun on Stowe's actual runs: shady, north-facing slopes hold snow longer than sunny ones. * Stress tests, not forecasts: the same winters replayed warmer. The model was checked against real snowpack measurements at 105 SNOTEL stations in the western U.S.; there are no SNOTEL stations near Stowe, so treat these numbers as a rougher estimate.

Stowe Snow Preservation Score

+1% more sun

Terrain holds snow better than 17% of Eastern & Midwestern resorts · 18% of all North American resorts

#55 of 66 in the East & Midwest · #177 of 216 overall

Stowe's runs get 1% more winter sun than the same slopes would facing every direction equally. Typical resort: 17% less.

How well Stowe's runs are oriented to hold onto snow. North-facing slopes get less direct sun and keep snow longer; south-facing slopes lose it faster. We measured the direction and steepness of 147 mapped runs and compared the sunshine they receive with what the same slopes would get if they faced every direction equally, so this score reflects terrain orientation only, not latitude or elevation (those are covered by the rain score above).
