The Best Time to Visit Mustang
Mustang's rain shadow keeps it dry through the monsoon — spring, summer and autumn all work. A season-by-season guide.
The best time to visit Mustang is wider than for most of Nepal, because the region sits in the trans-Himalayan rain shadow behind the Annapurna and Dhaulagiri massifs. That dry climate means spring, summer and autumn all work — and Mustang is one of the few parts of Nepal worth visiting during the monsoon.
The short answer
For the most settled weather and clearest mountain views, aim for spring (March-May) or autumn (late September-November). But because the high Himalaya block most of the monsoon, summer (June-August) is also a good window here while the rest of Nepal is wet. Winter (December-February) is cold and quiet, with some Upper Mustang lodges closed. Whenever you go, expect strong afternoon winds and cold nights at altitude.
Season by season
- Spring (March-May): Warming days, apple blossom in Marpha, and the spring Tiji festival at Lo Manthang. One of the prime windows for an Upper Mustang trek.
- Summer (June-August): Mustang's rain-shadow advantage. Dry and pleasant up the valley, though the approach from Pokhara through the Kali Gandaki Gorge can be cloudy and flights may be delayed.
- Autumn (late Sep-Nov): Crisp, clear and stable — arguably the most reliable all-round season, with the apple harvest in full swing.
- Winter (Dec-Feb): Cold and stark; Lower Mustang sights like the fortress village of Jharkot and Muktinath stay reachable on clear days, but services thin out higher up.
Timing the festivals
Culture, not just weather, draws many travellers to a particular month. The Tiji festival at Lo Manthang, usually held in May, is the biggest event in the Mustang calendar — three days of masked monastic dances in the walled city's square, set on dates fixed by the Tibetan Buddhist calendar. Because beds and permits both get tight around it, book well ahead if you want to be there. Lower Mustang has its own rhythm too: Marpha's orchards blossom in spring and are harvested in autumn, and various village gompas hold their own observances through the year. If a festival is your priority, pin down the exact dates with your agency before fixing flights, as they shift from year to year.
Good to know
- Wind: Strong winds funnel up the gorge most afternoons year-round — plan flights and longer walks for the morning.
- Altitude: Nights are cold in every season; pack warm layers even in summer.
- Plan around it: Match the season to your route with our Mustang itinerary, and sort the paperwork via the Upper Mustang permits and access guide.

With its dry, sunny climate and long usable season, Mustang offers more flexibility than almost anywhere else in Nepal — including the rare chance to travel comfortably while the monsoon soaks the lowlands.
Frequently asked questions
When is the best time to visit Mustang?+
Spring (March to May) and autumn (late September to November) give the most settled weather and clearest mountain views. Because Mustang sits in the Himalayan rain shadow, it also stays largely dry through the summer monsoon, making it one of Nepal's best monsoon-season destinations.
Can you visit Mustang during the monsoon?+
Yes. Unlike most of Nepal, Mustang lies behind the high Himalaya in a rain shadow, so it gets little of the summer monsoon rain. June to August can be a fine time to travel here, though approaches from Pokhara through the gorge may still see cloud and the odd flight delay.
What is the weather like in Mustang?+
Mustang is high, dry and windy. Days are sunny and the air is thin; nights are cold year-round and bitter in winter. Strong afternoon winds funnel up the Kali Gandaki almost daily, and at altitude temperatures swing sharply between sun and shade.
Is winter a good time for Mustang?+
Winter (December to February) is very cold, and many Upper Mustang villagers migrate to lower towns, so services thin out and some lodges close. Lower Mustang sights like Muktinath remain reachable on clear days, but expect hard frost, snow risk and a quieter, harsher experience.
When is the Tiji festival in Mustang?+
Tiji is held each spring in Lo Manthang, usually in May, on dates set by the Tibetan Buddhist calendar. Its masked monastic dances are the region's biggest cultural event, so many travellers time an Upper Mustang trek to coincide with it. Confirm the exact dates well ahead.
