1. Spring Season (March – May)

One of the most beautiful and magnificent seasons of all is spring, which offers a variety of blooming flowers, new vegetation, and brilliant blue skies for hikers, making it one of the most desirable times of the year. 

Between 25 and 30 percent of people make the journey during this time because there is little or no rain, and the weather is moderate, although it can be chilly at higher elevations. This is also the perfect time to hike and take in the stunning scenery of the several intriguing locations on the circuit.

2. Summer Season (June – August)

As the summer and monsoon coexist, the Annapurna region will experience hot and rainy weather at the same time in the summer. Annapurna circuit trek gets heavy shower throughout the monsoon season. Due to the constant rain throughout the rainy season, the trails become muddy and slippery. 

The water levels in rivers, streams, and waterfalls rise as a result of monsoon rain. This season consists of far more downsides than advantages. The pathways are frequently washed away and the hikers must be prepared for rock-falls and landslides in specific areas. 

3. Winter season (December – February)

Winter in the Himalayas is the coldest time of the year, with severe blizzards and heavy snowfalls. The bitterly cold and unpleasant temperatures force people from higher elevations to move to lower elevations to avoid the long and dreary winter.

At higher altitudes, the temperature drops significantly, making it challenging to survive. Heavy snowfall is a common occurrence that can result in the closure of certain routes, and most teahouses remain closed during winter due to locals migrating to lower elevations. The cold and snow can also lead to the closure of major passes and higher regions such as the Upper Mustang and Thorong La passes.

4. Autumn/ Fall season (September – November)

The best time to enjoy the breathtaking views of the Annapurna Circuit is during the autumn/fall season. This is when trekkers travel to the Annapurna region to hike on well-known routes like the Annapurna Base Camp Trek and the Annapurna Circuit Trek.

In autumn, the weather and temperature conditions are the most consistent throughout the year, with sunny, bright, and clear skies that offer alluring views. The trails are not dusty, and the nights are also clear, making it a great season to observe the stars. Rain is also unlikely during this season.

While trekking across the Himalayas on the Annapurna Circuit in autumn, hikers get to discover an entirely new area of stunning panoramas, passing breathtaking landscapes painted against an indigo backdrop.

Sickness & Prevention Measures

When trekking the Annapurna Circuit, the most important consideration is your health. As you ascend to higher altitudes, the risk of altitude sickness increases. The trek starts at a minimum altitude of 1,350m/4,429ft (in Kathmandu) and reaches a maximum altitude of 5,416m/17,770ft (at Thorong Phedi to Muktinath via Thorong La pass).

Travelers should be aware of the symptoms of altitude sickness and its remedies. Altitude sickness can manifest in various degrees, with common symptoms like headache and nausea. However, these symptoms can worsen and, in severe cases, even lead to death. It’s easier to travel to lower sections of the Annapurna Circuit than ascending to higher regions, so it’s important to plan your trek with proper understanding and prevention measures. Extreme altitude sickness comes in two different forms:

1. High Altitude Pulmonary Edema (HAPE): 


  • The lungs swell with fluid. 
  • Breathlessness, 
  • A dry cough, 
  • Pink or rusty spit, 
  • Blue lips, nails, and skin, 
  • Extreme exhaustion, 
  • Low fever, 
  • Gurgling breath, and 
  • Drowsiness

2. HACE (High Altitude Cerebral Edema): 


  • The brain swells with fluid. 
  • Seizures, 
  • Severe headache, 
  • Nausea, 
  • Loss of balance or coordination, 
  • Lethargy, 
  • Blurred vision;
  • Slurred speech, 
  • Confusion, and 
  • Altered behavior

As preventive methods, try to avoid any direct flight to high-altitude regions. If possible, hikers need to spend a minimum of two to three days for getting acclimatized. The acclimatization is a must before climbing above 2,500m/ 8,200ft. Get the guidance on High altitude sickness in Himalayas from Himalayan Glacier blog. 

In case of emergencies, contact your guides and get to the lower altitude as fast as possible with proper rest and care. Remember panic won’t solve the problem.


Despite the Annapurna Circuit’s high snowfalls, rough terrain, and challenging paths, it’s still worth visiting during the right season.
