Autumn and winter are the best times to go trekking in Nepal. The best time to go trekking in the Himalayas is between mid-September and mid-December. At this time of year, the weather is pleasant, neither too hot nor too cold. During the spring, the sun starts to warm up in the Himalayas, enabling trekkers to enjoy beautiful weather. Spring in Nepal is an excellent time for climbing trips because of the abundance of flowers.
Spring is the most favourable time to go trekking and climb mountain peaks. During the day, temperatures range between 16 and 23 degrees Celsius in the upper hill and mountainous regions, making days and nights much warmer. The skies seem to be clear, indicating that there will be no issues throughout the flight or bus ride. The fact that there are fewer trekkers at this time of year means that you are more likely to have the opportunity to explore more remote and unexplored areas of Nepal's Himalayas. As summer approaches, hiking at lower altitudes may become hot in the summer, and unexpected downpours can make trekking difficult and more dangerous.
Summer (June – August)
One must avoid trekking during summer due to the presence of monsoon rains and the difficult circumstances that one might encounter. Lower areas are muddy, and there are a lot of leeches there. The monsoon season in Nepal occurs throughout the summer months, resulting in moist and humid weather that makes trails muddy and scenery clouded, eventually leading to a failed trek.
Autumn is often regarded as one of the greatest seasons for trekking since it is hard to find any downsides to the bright sky and pleasant temperatures that it offers. The atmospheres have been cleaned of dust, resulting in crystal clear and breathtaking views of dense forests with snow-capped mountains sparkling in the distance. The weather remains stable, with a bright sky and days that seem to be becoming warmer. However, when the weather gets better, the number of travellers will grow, resulting in overcrowded routes.
Winter is a suitable season for treks in the Everest region and lower to mid-altitude pathways where the temperature is still acceptable despite the cold due to the reduced amount of people on the trails during this time. Because of the snow, the higher altitude routes are unreachable, and the risk is maximum owing to the freezing conditions.
