Annapurna Circuit Trek in September: what to expect

September is the end of the monsoon. Rain eases through the month and by late September skies begin to clear, though mornings can still be wet and trails muddy. Landslide damage to roads may linger from the rainy months, so confirm road conditions before you travel. Valleys are green and the air is clear after rain. Trekker numbers rise in the last week as autumn bookings begin. It is a good month for flexible trekkers who can wait out a few wet days, and a good moment to line up a partner for October. Watch the forecast in the days before you fly or drive out, and be ready to start one or two days later than planned.

Annapurna Circuit in September sees the end of the rains. Road conditions on the Marsyangdi side may still be poor early in the month, and the trail dries as September ends. Thorong La is usually open and lodges begin to fill late in the month.

General seasonal guidance, not a forecast. Conditions change year to year; confirm weather, flights and trail status with your guide or lodge before you go.
