Spring Season (March-May)

Spring is one of the most favorable seasons to trek. The weather is very stable and dry during this season. The moderate climate, neither hot nor cold, is perfect for trekking at high altitudes. It starts in March and ends in May.

The scenery is very beautiful in this season. There is no chance of rainfall and snowfall. So, many trekkers are attracted by this weather without any dangers. It is very crowded along the trail. 

A crystal clear view of majestic mountains melts your heart. Spring is also called a blooming season. So, you can see different kinds of flora and vegetation along the trail. The trees and forest are green, with many animals migrating to this place. 

Autumn Season (September-November)

Autumn is another feasible time to trek. The weather is very dry and stable. The pleasant weather makes the journey very comfortable. It starts from September till December. It is a great season for trekking. 

The temperature is very moderate. It ranges from 14 to 20 degrees. It cools down during the night up to -10 degrees. The chilly night is bearable with the help of warm clothes and blankets.

Autumn comes after the monsoon season. So, the rain clears out the clouds, providing the most amazing view of the mountains. There is a low chance of rainfall and snowfall. Therefore, trails are in the best condition to trek without injury. 

This is peak season, so you encounter many people along the trail. Finding accommodation is challenging. So, make sure you prebook to save trouble. You may need to share your bedrooms with strangers. 

Summer Season (June-August)

Summer is the worst season for peak climbing. It is very risky to trek during Summer. The trails are very muddy and slippery due to rainfall. Summer begins in June and lasts till August. 

Trekking in Summer is very challenging and can be unsuccessful. There is a high chance of landslides and floods. Leeches and other pests make the journey more uncomfortable. 

Rain clouds all over the sky obstruct the breathtaking views of mountains and landscapes. However, the heavy rainfall makes the surroundings very clean and dust-free. The view after rainfall is very bright and colourful. 

You will need extra thin clothing as clothes may not dry properly due to humid weather.

If you want to travel during Summer, early June or late August is the best time. There is less chance of rainfall. The advantage of trekking in Summer is less crowd. You can get lucky with discounts on accommodation. 

It is not recommended to trek in this season. Only a professional who loves adventure can trek. The rains make it very difficult. Also, packing is complicated as you must pack extra rain gear and waterproof stuff.

Winter Season (December-February) 

Winter is off-season for trekking. The weather is very cold and dry. The days are shorter. There is a high chance of snowfall, making the temperature more freezing. Heavy snow makes the trail very risky. 

December is the start of winter, ending in February. If you love the cold and want to trek in winter, early December and late February are best. You need heavy packing to prevent the cold. The trails are not crowded. You can even get discounts on night stays. 

However, there is no chance of rainfall, so the trails are smooth. The winter mountains are the best view that heals our souls. At the beginning of December, there is thin snow and light wind. With the start of January, the temperature drops rapidly with thick snow and frequent windstorms.
