Ski Resort Rain Risk

How much of each resort's winter precipitation falls as rain instead of snow, today and if winters run 2°C warmer. We rebuilt 40 winters of hourly weather at every resort's base, mid-mountain and peak and estimated rain vs. snow from temperature and humidity, hour by hour.

When might +1°C and +2°C happen?

Roughly +1°C by the mid 2030s and +2°C around 2050 for North American ski country — sooner if emissions keep rising, possibly never if they fall fast. It's already about 0.7°C warmer than the 1986–2026 average these numbers start from.

These are local winter warming above the average of the 1986–2026 winters we rebuilt (centered around 2006), not the global “1.5°C / 2°C above pre-industrial” targets, which start from the 1800s. The world has warmed about 1.37°C since pre-industrial times and is warming about 0.27°C per decade (Indicators of Global Climate Change 2025); North America's land warms roughly 1.5× faster than that, fastest in winter (U.S. National Climate Assessment). A rough guide, not a forecast: real timing depends on future emissions and varies by region and year.

The Rain Resiliency Score ranks resorts on three things at +2°C: how much winter precipitation falls as rain, how much of today's snow turns to rain, and how many significant rain days they get. It's a ranking, not a grade: 100 = least rain risk in the field, 50 = middle of the pack.
