Historical climate at one selected model cell. Higher routes, sheltered valleys and exposed ridges can differ substantially.
Model elevation: 3,540 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.
Selected cell: 30.7, 79.1
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.
Choose a specific route and check its distance, ascent, difficulty, current access and forecast. These are not supplied by the climate model.
This detail page remains available as a review page. Because of the persistent-snow signal, it makes no hiking-score or best-month claims.
30.7, 79.1 · 3,540 m
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.
At the ERA5-Land grid cell selected for Garhwal Himalaya, snow lies in all twelve months of the climate normal. A cell under year-round snow does not describe hiking terrain, so we publish no hiking score and no best months for this destination.
The record itself is complete: 306,864 hourly values from 1991 to 2025 at 30.70, 79.10, at a model elevation of 3,539.7 metres. Mean monthly temperature runs from -4 to 13 degrees, and the wettest month is July at 100 percent rain days. This page stays available so the decision to withhold can be checked.
Every figure comes from one selected ERA5-Land model grid cell at 30.70, 79.10, 3,539.7 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.
