FAQs on ACT Best Time
What is the best season to trek the Annapurna Circuit?
Autumn (September to November) and spring (March to May) are widely considered the best. During these seasons, the weather is stable, skies are clear, and mountain views are at their best, with spring offering blooming rhododendrons and mild temperatures, and autumn providing crisp air and excellent visibility after the monsoon. Autumn edges ahead for the most reliable weather, while spring wins on scenery.
Can you trek the Annapurna Circuit in winter?
Yes, but it's more demanding and best suited to prepared trekkers. The trail from Besisahar to Manang stays open and accessible in winter, while Thorong La Pass may close for a few days after heavy snowfall. You'll get quiet trails and clear skies in exchange for cold, snow, and the chance that the high pass is temporarily blocked.
Is the monsoon a good time for the Annapurna Circuit?
It's the least ideal season for most people, though not impossible. The monsoon (June to August) brings heavy rain, slippery trails, and limited visibility. The upside is solitude, and the rain-shadow areas around Manang and Mustang stay relatively dry, which is why some trekkers still go.
When is the best time to cross Thorong La Pass?
Spring and autumn are safest for the high pass. The most favorable seasons for crossing Thorong La are spring and autumn, when skies are clearer and conditions are more stable, whereas winter brings heavy snowfall and severe cold that can temporarily close the pass. Even in peak season, early mornings at 5,416m are extremely cold.
Which season has the clearest mountain views?
Autumn is the standout for visibility, with crisp, clear skies after the monsoon washes the haze away. Winter also offers exceptionally clear skies, and spring is excellent too, though it can grow slightly hazier toward late spring. Monsoon is the weakest for views due to clouds and rain.
When do I need to book accommodation in advance?
Mainly during the peak autumn and spring seasons. In peak seasons, teahouses can be fully booked, especially at popular stops like Manang and Thorong Phedi, while in off-seasons, such as winter and monsoon, trekkers can usually get a room without booking ahead. Note that in winter, some high teahouses close entirely, so it's worth confirming what's open before you go.
How cold does it get, and when is the coldest?
Cold scales sharply with altitude and peaks in mid-winter. January is the coldest month on the circuit, with high-altitude temperatures dropping to extremely cold levels, especially before sunrise. Even in the best seasons, nights at high elevations like Thorong Phedi fall below freezing, so warm layers and a properly rated sleeping bag matter year-round
