What these numbers describe
Historical climate at one selected model cell. Higher routes, sheltered valleys and exposed ridges can differ substantially.
Model elevation: 4,552 m · Historical period: 1991–2025
Trail wind is not available here. This model does not resolve exposed ridges or gusts; check a local mountain forecast.
How to read these figures
Selected cell: 32.2, 78.0
Temperature sampling window (local time, limited to daylight): 08:00–18:00.
A wet day has at least 1 mm of total precipitation (including snow water equivalent). It may rain for only part of the day.
A snow day meets either model threshold: 10% snow cover or 2 cm snow depth.

Months we do not recommend
9 months do not clear the gate
The record for these months is complete. They carry no hiking score because at least one critical component is at or below 20, and we would rather say so here than publish a weak recommendation.

Why most of the year is missing
We withhold the rest of the year because cold falls below the threshold at which we stop recommending a month.
In the remaining withheld months, snow cover is the limiting factor.
Conditions in August
The strongest scored month is August: about 9 degrees in the hiking window, rain on 38 percent of days, and 13 hours of daylight.
At 4,551.6 metres these figures describe altitude where conditions change quickly. They are a 1991 to 2025 historical mean, not a day.
What these figures cover
Every figure comes from one selected ERA5-Land model grid cell at 32.20, 78.00, 4,551.6 metres, averaged over 1991 to 2025. It describes that point rather than every route in the region, and it is not a forecast. Wind is coarse 10 metre grid wind, not a statement about exposed paths or gusts.
