The best piste skiing today
245 resorts ranked by groomed-run conditions. Surface quality, visibility, comfort and wind, updated every 3 hours.
Today's podium
Weather data from Open-Meteo, refreshed every 3 hours.
How the piste score works
Optimised for groomed-run skiing. Rewards moderate fresh snow, clear visibility and comfortable temperatures over raw powder depth.
Surface qualityDriver
Temperature, freeze-thaw timing, precipitation type and grooming context drive the corduroy quality. The best days are firm, grippy and carveable rather than slushy or icy.
VisibilityDriver
Flat light, heavy snow and fog reduce the experience because they make speed and terrain-reading harder on groomed runs.
ComfortModifier
Apparent temperature and wind chill modulate the score without overriding the snow surface. Cold enough to preserve the piste is good; brutal cold is less enjoyable.
WindModifier
Strong wind dents comfort and can flag operational risk on exposed lifts, but it is not treated as the whole story by itself.
Snow-depth gateGate
The v9 scorer reads base, mid and summit snow-depth anchors where available. Thin lower mountain cover caps otherwise good weather until the groomed surface has enough base.
Frequently asked questions
How often is this updated?
Every three hours. We pull fresh snow, wind and temperature data for every resort, recalculate each score, and save a snapshot.
How is the piste score calculated?
Each resort gets a score out of 100 optimised for groomed-run conditions. PeakWave uses a factor chain: surface quality and visibility are the main drivers, comfort and wind are bounded modifiers, and the v9 snow-depth gate reads base, mid and summit cover where available. Fresh snow helps only when it improves the groomed surface rather than masking thin cover.
How does this differ from the off-piste score?
The piste score rewards the ideal groomed surface temperature (-3 to -8°C), clear visibility, and comfortable conditions. The off-piste score rewards deep fresh snow, cold temps that preserve powder, and tolerates lower visibility. A resort can score 90/100 piste and 30/100 off-piste on the same day.
What is the luck factor?
It compares today's conditions to the historical average for that resort at this time of year. A positive luck score means conditions are better than usual; negative means worse than typical.
Where does the data come from?
Open-Meteo Weather API, which aggregates forecasts from global weather models. The same underlying data powers many snow forecast apps.
Do the scores account for lift closures?
Not directly. We score observable weather conditions. If wind is extreme the score reflects that, but we do not have real-time lift status data.
