Nakiska Climate Change Profile

Overall 50

Winter Resilience Score

More climate-resilient than 32% of Western resorts · 50% of all North American resorts

#103 of 152 in the West · #110 of 220 overall

What goes into it, compared with Western resorts:

  • Season length at +2°C 20% better than 4%
  • Rain on the snowpack at +2°C 40% better than 99%
  • Snowmaking weather at +2°C 10% better than 93%
  • Terrain orientation 30% better than 11%

* 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.

Nakiska Climate Change Takeaways

  • Rain potential: About 4.3% of winter precipitation falls as rain today, rising to about 11% with 2°C of warming. Ranks #46 of 152 Western resorts for rain resilience (#46 of 220 overall).
  • Season length: About 63 naturally skiable days a season today (Nov–Apr); about 39 with 2°C of warming (24 fewer).
  • Snow preservation: Terrain faces mostly northeast and gets about 23% less winter sun than neutral terrain. Its orientation holds snow better than 68% of Western resorts (67% of all North American resorts).
  • Base area viability: At risk: the 5,000' base has about 39 naturally skiable days a season today, about 16 at +2°C.

Nakiska Rain Resiliency Score

79

Less rain risk than 69% of Western resorts · 79% of all North American resorts

#46 of 152 in the West · #46 of 220 overall

About 4.3% of winter precipitation falls as rain today, about 11% at +2°C.

How well Nakiska'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.

Nakiska Season Length

63 days

More naturally skiable days than 3% of Western resorts · 9% of all North American resorts

#147 of 152 in the West · #201 of 220 overall

63 of 181 possible days today (Nov–Apr), about 39 at +2°C.

How many days a season Nakiska 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.

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 Nakiska's average snowfall. Melt follows the sun on Nakiska'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 Nakiska, so treat these numbers as a rougher estimate.

Nakiska Snow Preservation Score

−23% less sun

Terrain holds snow better than 68% of Western resorts · 67% of all North American resorts

#48 of 150 in the West · #72 of 216 overall

Nakiska's runs get 23% less winter sun than the same slopes would facing every direction equally. Typical resort: 17% less.

How well Nakiska'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 79 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).
