Traditional Trekking Seasons in Nepal

Historically, Nepal’s trekking has two main or peak seasons.

Spring (March to May)

• Winter (December to February)
• Monsoon (June to August)

Are Trekking Seasons Changing in Nepal and How?

The climate of the Himalayas is warming faster than many other regions in the world. It’s been reported that glaciers are retreating, snowfall patterns are also shifting, and monsoon rains are arriving at unexpected times. These alarming changes in warming don’t just impact snow and ice; they also affect the pristine trails of the Himalayas with an unpredictable weather shift.

Also, it affected the flow of rivers, which increases the risk of landslides and soil erosion, which will surely risk the lives of trekkers and the experience they want to get from the trekking trails of the Himalayas.

As these environmental changes gain momentum, so too does the pressing question: Are trekking seasons changing in Nepal? and how it is reshaping the trekking season in the Himalayas is mentioned below:

Warmer Temperatures at High Altitude

Trekking seasons are changing in Nepal, as you can see, there is an increasing temperature at high elevations, like the upper region of the EBC trek, or in the Upper Mustang Trek. Due to the melting of glaciers, there are shorter snow seasons, and earlier snowline retreats are resulting in unpredictable trail conditions.

Similarly, the unstable terrain makes increased chances of rockfall, soil erosion, and landslides which will surely impact when and how trekkers can safely traverse key regions of the Himalayan trekking trails.

Altered Monsoon and Rainfall Patterns

Traditionally, the monsoon season (June to August) is considered as a clear off-season. But now, rainfall timing and intensity are shifting which make it harder to define safe trekking windows and raise a crucial concern: Are trekking seasons changing in Nepal due to an unpredictable monsoon?

According to the Mountaineering guides, the late monsoon rains starts creeping into autumn season while there is shorter winter snow cover. You may even experience a sporadic rainfall during spring season. This will suddenly impact the old trekking boundaries in Nepal.

Retreating Glaciers and Snowline Changes

There is an alarming rate of melting of glaciers in the Himalayas. This changes snow coverage on high-altitude routes, as you can see snow-free trails when arriving earlier in spring, followed by the reduction of snowpack that once protected trails from avalanches.

There is an increased risk of outburst flood as glacial lakes are growing larger. The landscape is also playing a role when talking about the rising question again: Are trekking seasons changing in Nepal?

Trail and Pass Accessibility

There is blockage of trails due to ice even in early Spring in the high passes like Thorong La, Cho La, and Renjo La. It used to get blocked only in the early winter before, which proves that spring trekking windows are shifting.

The Autumn trekking windows are becoming less predictable so you have to adjust your trekking season while communicating with local communities and guides.
