If you’ve been dreaming of crossing through the valley of the far western Nepal in the Dolpo region, the success of your trip largely depends on one thing: the Upper Dolpo trek weather.
In this remote setting, weather changes everything, including the Upper Dolpo trek route.
Snow can close high passes, rain can make low passes slippery and cold nights at altitude can really test how good your gear (and your mentality) is.
This is why choosing the right month is really important.
Choose the right season, and the trek will seem to be pure magic – like a fun camp under prayer flags, with blue skies on the trail ahead.
Choose the wrong month and it will feel like you’re just trying to survive in high altitude conditions.
In this blog by Bold Adventures Nepal, you will find out the weather conditions of the Upper Dolpo region and when to trek for an enjoyable journey.
Why the Weather is Important for the Upper Dolpo Trek
The Dolpo trek weather is unlike anywhere else in Nepal.
Dolpo lies in the rain shadow of the Dhaulagiri and Kanjiroba ranges.
As a result, it has much less rainfall than other popular trekking areas such as Annapurna or Everest base camp.
In July, when monsoon showers flood most of the other trails, Dolpo, in comparison, is often dry and trek-friendly.
Don’t be misled, this doesn’t mean the Upper Dolpo trek difficulty is any lower.
Even in spring, you’ll see snow and feel icy winds when crossing some of the higher passes like the Kang La Pass.
There can be nights below freezing point, so you will need good sleeping bags, lots of clothing layers and potentially, more rest days in the trek if snow covers the route.
Now, just imagine.
- When you trek in April, the valleys burst with flora and fauna. Yaks graze peacefully in green meadows. Crystal Mountain, white and conical, shines out above the ridges.
- In October, the flat skies are razor-sharp. The golden barley fields glow. There is a chance you will spot a snow leopard near Shey Phoksundo National Park.
- In January, it is “game over”. The trails freeze, the villages shut, and only a handful of climatic climbers will dare go above the snowline.
Did you know? Each year, less than 500 trekkers do the Upper Dolpo trek. This is a drop in the ocean compared to Everest Base Camp. Therefore, understanding the Upper Dolpo trek weather is not only helpful, but critical if you want to make your trip not only safe, but memorable for the rest of your life.
Overview of Upper Dolpo Trekking Seasons
The weather in Upper Dolpo varies seasonally and each season is different.
Some seasons may be good for photographs and overall trekking conditions, while others may be for solitude.
Not only that, weather directly affects the Upper Dolpo trek cost.
Being attuned to the seasons allows you to determine when the best time for trekking is and derive the best out of it.
Let’s look at what the different seasons offer.
Spring (March to May): Wildflowers, Scenic Views & Open Trails
Of all the trekking seasons, this is one of the most suitable options for the Upper Dolpo Trek weather.
Warm days, nights close to freezing point and cleared tracks are what you can expect.
Flowers/vegetation cover the hill sides, the snow line descends and you see the sacred Crystal Mountain distinctly in the blue background.
Coming back to camping, long valley treks and physical challenges will feel like a piece of cake now.
For the majority, spring is the season to revive the life of Dolpo.
Summer/Monsoon (June to August): The Favorable Rain Shadow
Monsoon in the majority of Nepal brings rain, plenty of it.
However, Dolpo lies behind high Himalayan walls and in the rain shadow.
That’s why trekking remains possible during this time, especially around Shey Phoksundo National Park.
Lower parts of the trek will be marshy, but the higher parts are dry, serene and insect-free.
During this time, the valleys are green, yaks graze and rivers run full.
There are fewer trekkers in Dolpo during this season, so you will have an almost isolated camp trek.
Autumn (September to November) Clear Skies & Peak Season
Autumn is the time of preference for most trekkers.
Upper Dolpo weather is fixed, clear blue skies and all the fields are golden.
Autumn season is also the time when the harvest festival is celebrated by the villagers and many pilgrims approach Shey Gompa.
Passing high passes is also most rewarding in autumn – the panoramas reach far with little distortion.
The best chance to view wildlife, including the elusive snow leopard, is in autumn.
Autumn is Dolpo at its picture-perfect best for trekkers.
Winter (December to February): Snow, Silence & Isolation
During winter in Dolpo, there is silence, trails are under snow and villages are shut down.
At night, the temperature descends to a chill of -20 °C at high elevations.
Here, trekkers will be relying on insulated sleeping bags and careful preparation.
The silence is just incredible – only wind and prayers flags blowing in the wind.
This Upper Dolpo trek weather offers a surreal and risky experience.
For experienced individuals, winter treks here are best avoided.
