Highlights and low lights of Trekking in Nepal in September


Very peaceful trails

Since September is the start of stable weather, only a few tourists are heading for the trekking trail. Unlike October and November, you can enjoy the peace of nature and the hospitality of tea houses by yourself. The true blessing of nature can only be felt in solitude.

Green view:

As the monsoon rain stops, it’s time for the plant to get its life back. The terraced farm in the hilly region is all decorated with Paddy. In the upper region, you can see barley and wheat. Even the Evergreen subtropical forest gets lively with new leaves and grasses. Basically, the views around you are very natural.

Colorful alpine flowers:

In the trekking trails, you can see many amusing flowers that have just started to bloom. You can see Rockfoils, Moss Campion, and Edelweiss in the alpine region. In the topical forest, the Pine, Oak, and Rhododendron Forest greet you.

The magical view of the Mountains including a few clouds

Since the monsoon rains take away clouds and dust, September is the time for the best views. The mountains still have a thick layer of snow from June/ July that looks magnificent. The sky is quite clear and every mountain in the Himalayas range looks magnificent.

Lots of Waterfalls on the trail

As you head for the trek, you can see the multiple waterfalls that appear out of nowhere. September is the time when the rivers are full of water, and seasonal waterfalls get lively. You can see many such surprising waterfalls on the trek of the Annapurna and Everest region.

You don’t have to deal with the cold

The temperature in the mountains is always below freezing level, making it really hard to enjoy the trek. But September is the time when both days and nights in the mountains are warm. The average temperature remains above 10 degrees Celsius even on the trekking path. The chance of snowfall in September is close to nil. Even Everest Base Camp Temperature in September is bearable.

Less chance of high-altitude sickness

Due to warm and stable weather, trekking the September gets easier. Because of less pollution and greenery, the level of oxygen rises, thus making it easier for you to breathe. Also, the high temperature encourages you to drink a lot of water, thus reducing the cases of altitude sickness.

Fresh environment:

All of the above factors combine to create an excellent trekking experience. You don’t need to worry about the crowd, noise, and pollution. A clean and fresh environment is a major plus.

Low Lights

Flight may delay:

Although the chances are very less, we should face the issues with domestic flights. The hills and mountains of Nepal decrease the visibility of airplane. Thus, until and unless the weather is very clear with no chance of rain, they do not fly the plane. The delay can last several hours.

Might to deal with Rain:

Although September is not exactly the month for the monsoon, we can ignore the slight chances of rain. As the humidity is still quite high, rain might disturb your trek, especially in the evening. Do carry waterproof trekking shoes and a raincoat to avoid any chances of occlusion rain.

The trail might be wet

As mentioned above, the chances of rainfall still prevail in September. Since the trail is still wet from the monsoon rain, additional water can make it quickly slippery. You need to avoid walking on the steep landscape right after the rain.

Can’t have a mountain view for the whole day

The views in the mornings are relatively clear. From sunrise to mid-day, the mountains look more than magnificent. But as the evening falls, the cloud might block the view. Thus, it’s important that you reach the destination in the daytime and avoid walking in the Evening time.
