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.
Snow quality (fresh snow, rain damage, wind transport), stability weather proxies (wind loading, rapid warming, solar radiation), freeze-thaw cycle, and snow coverage. Seasonally weighted.
Best 5-hour contiguous daylight block scored for ridge wind, skinning comfort, visibility and route-finding, precipitation, and solar conditions.
Full weight March to May when overnight refreeze determines corn quality. Scales down to 35% in deep winter when the snowpack stays cold regardless.
Conditions derived at valley, mid-mountain, and summit using lapse rate and altitude wind fields. Weighted 15/50/35 for ascent time spent.
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?+
A dual-layer composite: Layer 1 (45%) assesses all-day snow conditions including fresh snow, stability weather proxies, freeze-thaw cycle quality, and coverage. Layer 2 (55%) finds the best 5-hour touring window and scores it for ridge wind, skinning comfort, visibility, precipitation, and sky conditions. Interaction ceilings prevent either layer from dominating unrealistically.
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.
