What these numbers describe
Historical climate at one selected model cell. Higher routes, sheltered valleys and exposed ridges can differ substantially.
Model elevation: 4,296 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: 28.5, 83.9 · southern Annapurna trekking-corridor cell
The massif-centroid cell is a permanent glacier-indicator cell. This cell represents the established southern trekking corridor at a 4296 m model elevation rather than glacier terrain.
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
5 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 December to April are missing
In 5 of twelve months, snow lies on at least half the days at the selected grid cell. We withhold December to April not because nothing happens there, but because snow cover turns the question from a hiking decision into a winter one.
Conditions in July
The strongest scored month is July: about 9 degrees in the hiking window, rain on 100 percent of days, and 14 hours of daylight.
At 4,296 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 28.50, 83.90, 4,296 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.
