The best trekking seasons in Nepal are Spring (March to May) and Autumn (September to November). Spring and Autumn are ideal for outdoor activities such as trekking, Peak Climbing, and Hiking because the weather is typically stable, with clear skies, dry conditions, and comfortable temperatures.
Autumn's mild temperatures and clear skies make for breathtaking Himalayan views. Autumn is a well-liked time of year for trekking in Nepal for anyone who wants to visit Nepal because the trails are dry and the vegetation is vibrant.
It's a beautiful time to trek in Nepal in the spring because the weather is mild and the flowers bloom. The warmer temperatures and clear skies allow you to see the mountains. High-altitude treks like the Annapurna Trek and Everest Base Camp Trek are fantastic in the spring.
Winter (December to February) can bring frigid temperatures and trail closures due to snow at higher elevations. The Annapurna region and some of the Langtang treks are examples of lower-altitude treks that are still accessible and offer exciting experiences. During this time, you can visit Chitwan and Bardiya National Parks to learn more about Nepal's incredible wildlife.
The monsoon season, which lasts from June to August, brings heavy rains and high humidity, making trekking challenging. The strong winds, rain, and sporadic clouds obscure the view.
The trails may be slick and muddy, so trekking is generally not advised during this time of year. However, trekking is possible in the dry regions (such as Upper Mustang and Upper Dolpo).
Given that June is the hottest month in Nepal and the summer monsoon occurs between June and September, these aren't the ideal times to travel if you want to go hiking. However, seeing the nation thriving with newness and growth is beautiful. Winter is very chilly, especially in January and February. You'll be among the only visitors in the mountains if you dress warmly.
The best times to trek in Nepal are in the fall and spring. It is dry, clear, and stable outside. Flight cancellations and delays are uncommon at this time of year. However, the monsoon season is particularly prone to them. Additionally, heavy fog frequently causes flight cancellations in the winter.
