When to go? — Select target date
❄️ Powder score is a reference index from forecast snow, wind, and temp. It is not ski safety or go/no-go advice. Resort official info, JMA, and on-site judgment come first (beta, personal project).
Snowfall is elevation-adjusted. We fetch Open-Meteo per resort (lat, lng, elevation), so nearby resorts can differ by grid; when they do we show the nearby resort’s forecast and mark it “(nearby)”. Check JMA for warnings. Avalanche, backcountry, and off-piste are out of scope. Days 3–4 are indicative; beyond that, forecasts vary more.
