Annapurna Circuit Trek Weather in September

Many veterans classify Annapurna Circuit Trek weather into two parts. One is post-monsoon weather and the other is stable weather

Post-monsoon weather starts in early September. During September, Nepal experiences the end of its monsoon season. Although some parts of the region may still experience rainfall during this time. Annapurna region receives slight rainfall this month, particularly in the lower altitude areas. So if you are planning for ACT in September, then you must prepare for occasional rainfall.

Hence, the routes are sometimes wet and slippery but not as frequently as during the monsoon season. The weather also doesn’t change as much as in the monsoon season. However, the day becomes a bit chilly, and nights and mornings are reasonably cold.

During late September, the post-monsoon season stops and the autumn season begins. The late September to late October is the perfect time for trekking ACT. The weather is clear and visibility is not affected by either rainfall or snowfall. Hence, you can enjoy the breathtaking views even more freely.

You can experience the stunning views of local settlements, hills, and mesmerizing mountains from very far away. It is wise to start trekking the Annapurna Circuit in late September. However, keep in mind the weather is dynamic in the higher altitudes.

Food and Lodge During September

Annapurna Circuit Trek in September is also famous for the teahouses that you will come across for food and lodges. But at the beginning of your trek, you will stay in Kathmandu and Pokhara. There you will have a choice of different hotels. You can choose from cheap but budgeted hotels or expensive three-star hotels.

September is a beautiful time especially the late month when there is very minimal chance of rainfall. This time the number of tourists also increased so the accommodation and teahouses have high demand. This will result in an increase in their prices along with the increased services as well.

As you start trekking from Pokhara towards the Annapurna Circuit Trek, you will come across small teahouses. They have limited services like rooms with double beds, and attached bathrooms. So you may have to share a room with another trekker along with your bathroom and sink.

If you are a female trekking individually, then you can get a private single room without paying extra. During the night, you will get fluffy pillows, blankets, and bedsheets. Make sure to keep yourself warm at night so you will get extra blankets and bedsheets if you need them.

Some teahouses can provide extra services if you pay extra. The extra services include charging ports, hot drinking water, hot showers, single bedrooms, and a WIFI connection. However, as you climb more altitudes, some of these services are not available.

You will get minimal services in the top altitude teahouses which are often open in September. These teahouses are often closed in the winter and rainy seasons with the fear of landslides and snowstorms.

On food, it is like your lodging services. First, you can have unlimited menu options in the three-star hotels of Kathmandu and Pokhara. You can also find different types of menus from local Nepali and Newari to western cuisines. Some of the menus are Italian, Australian, British, Japanese, Thai, and Continental dishes.

During the trek, you will have three-course meals: Breakfast, Lunch, and Dinner. As the altitude increases the menu in your food services becomes limited. You can have local Newari Dal Bhat and Roti to Western breakfast with bread, eggs, macaroni, spaghetti, dumplings, pizzas, and burgers.

The teahouses at the top of the Annapurna Circuit Trek might have only local delicacies. You can have local foods like Rice, Lentils, Wheat Bread, Dhindo, and green vegetables. As September is quite a popular month of trek, you might find a few more food items.

However, you must also consider that the route is very crowded at this time. So please be sure to book your trek early to get the best food and lodge services during your Annapurna Circuit Trek.

Please keep in mind that food and lodging costs are high this month due to a large number of visitors trekking during this period. This is because of the tough months preceding and succeeding the Spring season.

Chances of Altitude Sickness in ACT

Altitude sickness is a possibility during the ACT trek in September since you are trekking above 4000m. They are more likely to occur after reaching an altitude of 2500m and the possibility increases even more after 3500m.

To avoid altitude sickness, it’s important to learn about the illness, its symptoms, and how to prevent it. Symptoms may include a dry throat, feeling cold, headaches, fever, nausea, vomiting, joint and back pains, dizziness, and more.

One of the main reasons for altitude sickness is ascending too quickly. Gradual ascent and descent will give your body time to adjust to the climate, altitude, and temperature. Avoid ascending continuously as this can make it harder for your body to adjust.

When you’re at a higher altitude, the level of oxygen decreases. You will feel harder to breathe causing your body to be more susceptible to sickness. To help prevent this, trekking guides and experts often designate one or two days as rest or acclimatization days. Additionally, dehydration can also lead to altitude sickness, so be sure to drink plenty of water and keep warm during your journey.

It is important to stay warm if you want to avoid altitude sickness. You can do this by wearing warm clothing. You can also be warm by drinking hot beverages such as ginger tea with honey. These drinks will help keep you warm throughout your trek.

However, it is important to bring medicine for altitude sickness, like Nifedipine. This medicine can help relieve symptoms of the sickness. However, if they persist, you must quickly descend to a lower altitude. In some cases, altitude sickness can become so severe that you may need to stop trekking altogether. If this happens, you must immediately contact your travel agency for your rescue via helicopter.
