Choosing the best season for Annapurna Circuit trek can significantly enhance your experience.

Whether you’re seeking solitude on snow-dusted trails or festive vibes during the peak season, timing your adventure with insight into the circuit’s weather patterns is key to a successful journey.
Understanding the weather and seasonal changes of the Annapurna Circuit is essential for planning a safe, scenic, and enjoyable trek. Below is a comprehensive breakdown of temperature, altitude, climate conditions, and tips to prepare for the Annapurna Circuit Trek.
How High Does the Annapurna Circuit Go?
The Annapurna Circuit reaches its highest altitude at Thorong La Pass, which towers at 5,416 meters (17,769 feet) above sea level. This iconic mountain pass is not only the pinnacle of elevation on the trek but also the most physically and mentally demanding section. Due to its high altitude, trekkers often start the ascent well before sunrise to avoid strong afternoon winds and ensure a safer crossing. Snow accumulation can make the pass dangerous or even impassable during the winter months, adding to the challenge.
Acclimatization is essential for safely reaching Thorong La. Most itineraries build in rest days at moderate altitudes, such as Manang (3,519 meters), to help the body adapt to the decreasing oxygen levels. Trekkers who ascend too quickly risk acute mountain sickness (AMS), which can be serious at this height.
