The best ski touring today
245 resorts ranked for ski touring. Snow quality, stability weather, freeze-thaw cycle, and the best 5-hour touring window, updated every 3 hours.
Weather conditions only. This score does not assess avalanche risk. Always check your national avalanche bulletin and make your own terrain decisions before touring.
Today's podium
Weather data from Open-Meteo, refreshed every 3 hours. Always check local avalanche bulletins before touring.
How the touring score works
A dual-layer composite with elevation-derived conditions. Scores the full touring experience from overnight refreeze through summit conditions and descent timing.
Descent qualityDriver
Fresh snow, rain damage, wind transport, crust and coverage shape the quality of the ski down.
Touring windowDriver
The scorer looks for a usable daylight block with manageable ridge wind, skinning comfort, visibility, precipitation and solar effects.
Freeze-thawDriver
Overnight refreeze and daytime warming matter most in spring, when corn timing can make or break the descent.
Safety signalsSeparate
Avalanche danger, wind loading, rapid warming and storm flags are displayed as safety context. They are not a substitute for official local avalanche guidance.
Frequently asked questions
How often is this updated?
Every six hours, at 00:00, 06:00, 12:00 and 18:00 UTC. We recalculate each resort's touring score from fresh weather data and save a snapshot.
How is the touring score calculated?
PeakWave uses a factor chain for route-quality conditions: descent quality, trail-breaking effort, coverage, freeze-thaw timing, ridge wind, visibility, precipitation, comfort and solar effects. It looks for a usable touring window but keeps avalanche and storm signals separate from the experience score.
Does this assess avalanche risk?
No. The stability weather proxy scores weather patterns that correlate with instability (wind loading, rapid warming, precipitation intensity), but it is not avalanche risk assessment. Always check your national avalanche bulletin before touring.
Why 5 hours and not 3 or 4?
A typical alpine tour takes 4.5 to 6 hours. A 4-hour window captures the ascent but misses the descent conditions. The 5th hour (typically 11:00 to 12:00) is exactly when temperatures cross zero, wet instability rises, and corn transitions to mush. Scoring this hour penalises days where the descent is dangerous.
What is the freeze-thaw score?
In spring touring, the overnight refreeze quality is the single most important variable. A hard overnight freeze (-8 to -12C) creates perfect corn the next morning; a marginal freeze (-2C) gives breakable crust. The freeze-thaw score captures overnight refreeze depth, soil temperature effects, and morning warming rate.
What does Whiteout mean?
A score below 25 earns the Whiteout label. The most common reason a touring day is terrible is visibility-related: cloud immersion, fog, heavy snow, spindrift. It immediately communicates the dominant failure mode.
Where does the data come from?
Open-Meteo Weather API, which aggregates forecasts from global weather models including ECMWF and GFS. Altitude wind fields (80m/120m) provide ridge-level wind estimates.
