September is a good month for North Sikkim, with some trade-offs

The rains ease and the valleys reopen. Lachung and Yumthang are green and quiet, and in 2026 Lachen permits resumed around 11–12 September. Showers and slides are still possible in the first half. Late September brings clearer skies and the first autumn colour above Lachung.

Weather: Lachung 8 to 17 °C; showers easing
