The best time to trek the Nar–Phu And Annapurna Circuit is usually found somewhere smack in the middle of autumn or spring. The beginning or end of either season is a little riskier since weather patterns can fluctuate year on year.

Summer is monsoon season in the Annapurna Mountains, so you risk having to hike in heavy downpours in the lower altitudes. This can make trails slick and increases the chances of falling. Also for some, the humidity might be unpleasant.

December to February are winter, and it's bitterly cold. Further, you risk mountain passes being closed if there are large dumps of snow. Also, and very importantly, Phu is largely abandoned by residents in winter for warmer locations. So you won't experience the usual vibe of this village if you visit in winter.

The better weather that accompanies autumn and spring in the Annapurna Mountains naturally means busier trails at these times of year.

That said, happily this only really applies to the main Annapurna Circuit route. The Nar and Phu Valleys are never crowded. This is because most trekkers don't make the effort to enter these side valleys. So even if you're not a huge fan of busy trek routes, you could still trek during either of the peak seasons and have part of that trek be quiet.
