Trekking in the Annapurna Region is matchless in spring (March to May). The weather is warm during the day and cold at night. The average daytime temperature is 12°C to 20°C (54°F to 68°F) and it can drop to freezing temperatures during night. The forests are green, and rhododendrons bloom, making the trail vibrant. It is a busy time of the year and the trails will be full of trekkers. It’s important to prebook the lodges.
This region receives a lot of rainfall in general, so monsoons will be extremely wet and humid, with temperatures ranging from around 15°C to 25°C (59°F to 77°F). The downside of the monsoon is hovering clouds affecting visibility and slippery trails with leeches all along. The roads leading up to the trails can be affected by rockfall and landslides. While early June and late September are still advisable for trekking, July and August are out of the option. Not many people trek during the peak monsoon, so hotels aren’t fully operational.
It is the most popular time of the year to trek with clear skies, mild temperatures, and relatively stable weather conditions. The monsoon rains will have subsided, and visibility of the mountain ranges is excellent. There’s a perfect mix of greenery and colors in the hills and forests. Sunrise and sunsets are breathtaking. The temperatures range between 10°C to 20°C (50°F to 68°F) and drop lower with increasing elevation. As the region is very accessible, trails and lodges are extremely busy this time around.
Winter is a great time to trek in the lower Annapurnas. As we don’t reach significant elevation, the mountains look sparkling white on non-gloomy days. The temperatures go between 5°C to 15°C (41°F to 59°F) during daytime and can go lower at night. It is cold, but still very doable with the right preparation. Some parts of the trails can get slippery due to frost and patchy snow. The trails are not very busy and lodges are operational.
