Trekking in Nepal in September-Weather Guide

Is September a Good Time for Trekking in Nepal?

Yes, September is a time for trekking in Nepal because the country is slowly coming out of the summer monsoon season. This means that people who go trekking can enjoy trails, lush green hills, roaring waterfalls and improving mountain views before the busy October trekking crowds arrive.

Actually, September is a month because the weather gets better every week and it rains less and less across most trekking regions. From our experience of leading treks over Nepal, the middle to late part of September is the best time for trekking. The trails are in condition the skies are clear and there are fewer people around. This makes September the time for travelers who want to see nature to take good photos and experience the real culture of the Himalayas.

What Is the Weather like in Nepal in September?

The weather in Nepal in September is changing from the monsoon season to the autumn season. This means that it rains less across the Himalayas. As a result, the air becomes cleaner, the mountain breeze feels refreshing and trekking conditions get better every day.

In September there might still be some short afternoon showers. As the month goes on long periods of rain become less common. From our experience of guiding treks over Nepal late September usually has stable weather, dry trails, excellent visibility and comfortable hiking temperatures across most trekking regions.

Does It Rain During September Trekking in Nepal?

September is a great month for trekking in Nepal. People call it the "month of two halves" because the weather changes a lot as the month goes on. At the start of September, it is still possible to get some rain in the afternoons because the monsoon is ending. By the middle of the month, it gets much drier and the sun comes out more often. This means you get to see the mountains clearly.

Here, we have been leading treks in Nepal for a time, and we have noticed that it rains less and less as September goes on. The second half of the month is usually a time to go trekking because the weather is stable. You get to see the forests looking really green the air is clean. The trails are dry. It is also time to go trekking before it gets busy in October.

Places like Kathmandu, Pokhara, Besisahar and Syabrubesi are usually warm during the day with temperatures between 20°C and 28°C. The higher destinations like Namche Bazaar, Manang, Annapurna Base Camp, Everest Base Camp and Thorong La Pass are cool during the day. We think September is a time to go trekking because the temperatures are perfect with warm afternoons, cool mornings and fresh mountain breezes.

Do Mountain Nights Freeze During Trekking in Nepal in September?

Mountain nights can become very cold during trekking in Nepal in September above 4,000 meters. However lower valleys are comfortable at night while only the high alpine regions get close to or below freezing.

From our experience guiding treks across Nepal villages below 3,000 meters usually have sleeping conditions. On the hand, popular high camps like Annapurna Base Camp, Thorong Phedi, Thorong High Camp, Everest Base Camp, Kala Patthar, Larkya Phedi and Gorakshep get much colder after sunset. Therefore, carrying a quality sleeping bag and warm clothing is essential for a night’s sleep during trekking in Nepal in September.

Night Temperature in September by Elevation

Will You See Snow on the High Passes During Trekking in Nepal in September?

Yes, you will see snow on Nepal’s mountains during trekking in Nepal in September. Although deep snow on the trekking trails is uncommon in September because early autumn arrives before the winter snowfall. Famous high passes remain open, dry and safe for trekking throughout the second half of the month.

Popular crossings such as Thorong La Pass, Larkya La Pass, Cho La Pass, Kongma La Pass and Renjo La Pass usually have walking trails. However, morning frost or thin patches of old ice may occasionally appear near the highest points. From our experience September provides trail safety because winter snow has not yet accumulated while the surrounding Himalayan peaks remain beautifully covered with permanent snow during trekking in Nepal in September.

High Pass Conditions in September

High Pass | Elevation           | September Trail Condition |


Thorong La | 5,416 m             | Mostly dry                |

Larkya La  | 5,106 m             | Clear trail               |

Are Nepal Trekking Trails in September Muddy or Slippery?

The condition of trekking trails in Nepal during September depends on when you trek. This is because September is the time when the monsoon season is ending and the dry autumn season is starting. So, if you trek in September the trails below 3,000 meters may still be damp after some rain. If you trek in late September the trails will be firm, dry and much safer.

From our experience guiding treks in Everest, Annapurna, Langtang and Manaslu we have seen that the trails get better every week as the monsoon season ends. The stone steps become less slippery the forest paths dry out. The risk of landslides decreases significantly by the second half of September.

Trail Conditions in September by Elevation

| Elevation                      | September     | September       |


| Below 2,000 m (6,562 ft)       | Damp forest trails   Dry and firm         |

| 2,000–3,000 m (6,562–9,843 ft) | Some muddy sections | Mostly dry           |

| Above 3,000 m (9,843 ft)       | Generally stable    | Excellent conditions |

Above 4,000 m (13,123 ft)      | Rocky and dry       | Dry and safe         |

Trail maintenance improves.


Trail Safety Tips

Listen to your guide.

Are there Leeches on the Trails During Nepal Trekking in September?

Yes, leeches can still be active during September. This is especially true in wet forests below 3,000 meters. The leftover monsoon moisture creates an environment for them. They are easy to manage. They also disappear completely as you climb into the Himalayan regions.

From our guiding experience leeches are mainly found on forest trails around Annapurna, Langtang, Mardi Himal and the lower Everest approach during the first half of September. So, carrying a packet of salt or using insect repellent is usually enough to prevent any problems. Trails above 3,000 meters remain completely free of leeches throughout the trekking season.


Where Leeches Are Found during September


| Elevation                       Leech Activity      |

 

| Below 1,500 m (4,921 ft)       | High in wet forests |

| 1,500–2,500 m (4,921–8,202 ft) | Moderate            |

| 2,500–3,000 m (8,202–9,843 ft) Low                 |

| Above 3,000 m (9,843 ft)       | None


Trekking Regions for September


| Trekking Route      | Early September             | September |

 

| Annapurna Base Camp | Some leeches in forests     Rare           |

| Mardi Himal         | Possible below Forest Camp  | None           |

| Langtang Valley     | Occasional in lower forests | None           |

| Manaslu Circuit     | Some lower sections         | Very rare      |

| Everest Base Camp   | Rare                        | None           |


How to Prevent Leeches


Apply insect repellent.

Carry a packet of salt.

Wear trekking socks.

Use hiking pants.

Stay on the trail.

Avoid standing in grass.

Check your boots occasionally.


Good News for Trekkers in September


Leeches disappear above 3,000 m.

They are harmless.

They do not spread diseases.

Salt removes them instantly.

Dry weather reduces their numbers quickly.

Late September is almost leech-free.

Higher alpine trails remain completely free of leeches.

They rarely affect your trekking experience.

Can You See Clear Mountain Views During Trekking in Nepal in September?

Yes, September offers mountain views, especially in the morning. The air gets cleaner every day after the monsoon season. So, trekkers who start hiking early enjoy views of Nepal’s highest mountains before clouds form in the valleys.

From our experience leading treks in Nepal the best views are usually between 6:00 AM and 10:00 AM. Light clouds form later as warm air rises to the Himalayas. In September early risers get views of Mount Everest (8,848.86 m/29,031 ft) Annapurna I (8,091 m/26,545 ft) Dhaulagiri I (8,167 m/26,795 ft) Manaslu (8,163 m/26,781 ft) Machhapuchhre (6,993 m/22,943 ft) Ama Dablam (6,812 m/22,349 ft) Langtang Lirung (7,227 m/23,711 ft) and Ganesh Himal I (7,422 m/24,350 ft).

What Should You Pack for September Weather While Trekking in Nepal?

Packing for trekking in Nepal in September is easy if you are ready for two weather conditions. This is because warm valleys and cool mountains need clothes. So, bring clothes for sunny afternoons, reliable waterproof gear for occasional showers and warm insulation for chilly mornings and high-altitude evenings.

From our experience guiding treks in Nepal the weather can change quickly as you climb from Kathmandu (1,400 m/4,593 ft) and Pokhara (822 m/2,697 ft) to places like Annapurna Base Camp (4,130 m/13,550 ft) Everest Base Camp (5,364 m/17,598 ft) Thorong La Pass (5,416 m/17,769 ft) and Larkya La Pass (5,106 m/16,752 ft).
