Within the short distance of 183 km width, the altitude varies from 50m from sea level to world’s highest 8848m. Hence, the weather and climate precisely depend on topographical extremities and altitude of the area.
Annapurna Base Camp Weather September
The best time for trekking in Nepal allover is autumn, with the favorable weather and impressive views. And September falls under autumn season. Thus, it is an obvious best time and most popular trekking season for Annapurna Base Camp too. This month welcomes you with stunning mount views and clear skies all around.
At the same time, dust & pollution are already washed by monsoon rains. You can experience the clean, fresh, and vitalized area.
But as it’s the end of monsoon, heavy monsoon rain along with thunderstorms can linger on as the weather cools down to pleasant temperatures for trekking (Especially in early September). The surrounding can get hazy and dust produced can obscure the mountain views as winds get stronger. Being a rain shadow area, Annapurna region receives far less rain than in others. Although not sheltered from all rain, the northern section of the trek gets about 10% of less fall.
The weather is generally warm with an average day temperature of 15 degrees Celsius and night temperatures above freezing.
As you get higher in altitude temperatures drop considerably. From 4000m up, the days are colder and evenings/early mornings are more chilly.
The night sky is the best during this period. You will enjoy a billion stars that appear every night in bright clarity.
Weather temperatures and conditions change as you go up in altitude or descend. Likewise, there are variations depending on the points of the trek. Always expect passes and base camps to have more extreme conditions.
In September, it is possible to avoid the winter cold as well as the muds due to summer rains. Also, it is least rainy and the atmosphere is particularly transparent so that you can watch the snow-capped mountains at great distances.
If the wind strength, cloudiness, and rate of snowfall are preferable; September is also good for mount expeditions and climbing.
Annapurna Base Camp trek is a moderate trek accessible to all age group. As September is a high season, there might not be any problem trekking or weather wise. In this month, you can even trek alone or independently.
Vegetation during September
July and August (prior to September) are the monsoon season of Nepal. Though the condition of surrounding becomes hazy and humid, the whole land rejuvenates in full vigor.
When September rolls around, the clouds leave their hold of the sky creating a perfect backdrop for clear and blue skies. The mountains wake up from their deep slumber of Monsoon and display their full bloom of beauty. This makes for a perfect trekking season.
Raging rivers, green forest with lush vegetation, and cascading waterfalls have always been the best part. Another plus point for September is green yak pastures on the higher elevations offering the best snapshot spots.
Due to all these positive influences, the number of trekkers in September are increasing in Annapurna Region yearly.
Annapurna Region Weather Forecasts
As like the weather of Nepal, weather in Annapurna Region gets fickle at times. Always keep in mind that the weather can be unpredictable as the Himalayas create their own weather, regardless of the season. Thus, it is always best to plan ahead based on the weather forecast.
In the high mountains, the weather can vary greatly depending on the meteorological situation, so it’s better to be updated about the forecasts or to rely on expert guides. This will make you more psyched up.

Annapurna Base Camp Difficulty in September
Weather in Nepal is not constant throughout the year especially in the month of September. The month of September was supposed to be the clean and nice weather but past few years have been challenging with non-stop rain throughout the month. Usually, it is raining at night and leave the sky nice & clean during the morning and partly cloudy the day.
In Annapurna Base Camp, the views become more dramatic while trekking within the September month. The north side of the Himalayas is in shadow which means the mountains somewhat block the rain. The skies get cloudy and it may rain occasionally. Even in the clear sky, the views are not good as during the trekking season. Chances of trekking routes blockade by landslides if the condition gets adverse.
Another downside is as this is the peak season, flights and hotels are sometimes fully booked and rates are higher. The trails can be busier as well.
However, this isn’t it, you may also have problems getting decent guesthouses without reservations.
What to Pack
Gears and clothing during the trek depend on place and time but for high altitudes like ABC, it is recommended to have both light and warm clothing. Getting the right gear is really essential.
Highlighting significantly specific pieces, I would never skip following pieces:
- A good, sturdy, and waterproof pair of trekking boots (make sure they are properly broken in)
- A good quality down jacket with more baffling and more down-fill.
- Water bottles with water purifying tabs (to be completely hydrated along the trek)
- Sun hat & sunglasses
- A light sleeping bag & sleeping liner
- A lightweight & durable duffel daypack
It would be excellent if you plan your trek from mid-September onward. It can skip some rain showers. To avoid the possible rainfall, bring light and waterproof gears. A light breathable rain jacket, raincoat or umbrella is advisable. Pack sweaters and down jackets for the evening. At the high altitudes, fleeces, hat, gloves, scarf, sunscreens, medical-kits can work wonders.
Hence in September, you can fully enjoy Annapurna Base Camp if you prepare yourself well. The pleasant temperature, concrete panorama, and unique socio-culture of locals will undoubtedly create a lifetime memory.
