Cold desert climate. -20°C in January, 35°C in July. Very little rain, very clear skies. Here is what each month actually means for your trip.
| Best months | May–June and September for ideal all-round conditions and comfortable temperatures. For Deosai itself, aim for late June through September — it is usually snowbound until around mid-to-late June. |
| Peak season | July–August. Busy, hot in the valley. Best for Deosai brown bears and K2 trek season. |
| Spring blossom | April. Apricot and cherry orchards. Beautiful but roads may still be clearing from winter. |
| Winter | December–February. Extreme cold (-20°C possible). Most facilities closed. Flights suspended. For hardy travellers only. |
| Flights | Most reliable May–October. Winter cancellations can strand you for days. |
