Tawang Weather Month by Month

Three altitudes matter on this trip. Dirang at 1,560 m is mild all year and rarely drops below freezing. Tawang town at 3,048 m has cold nights from October to April. Sela Pass at 4,170 m and Bumla at 4,633 m are alpine — freezing nights are possible in every month of the year.

Rainfall is heavily front-loaded on the southern slopes. Bhalukpong and the Kameng gorge take far more monsoon rain than Tawang, which sits in a partial rain shadow. That is why the road, not the destination, decides your monsoon risk.

Tawang town: −6°C to 6°C. Sela: −15°C to −2°C. Very little rain, but snowfall events of 15–60 cm at the pass. Roads are cleared but slow; chains or a high-clearance vehicle are sensible. Hotels run on limited heating and hot water is timed.

Tawang town: −1°C to 12°C rising to 3°C to 16°C. Occasional late snow at Sela in March. April brings the first reliable dry road conditions and the rhododendron bloom. Afternoon cloud builds from mid-April onward, so start early for clear views.

Tawang town: 6°C to 19°C. Pre-monsoon showers begin in May and become daily by mid-June. The gorge road below Dirang starts to slide from about the third week of June. Sela is usually snow-free on the road but the surrounding slopes still hold drifts.

The wettest weeks of the year, with 400–600 mm falling on the southern approach. Tawang itself gets far less, often sitting above the cloud deck. Expect at least one delay of two hours or more on the Bhalukpong–Dirang stretch. Leeches appear on forest trails around Eaglenest and Shergaon.

The monsoon withdraws through the first half of September. From late September, visibility is the best of the year. Tawang town runs 4°C to 17°C in October and 0°C to 13°C by late November. Almost no rain. Cold, still, clear mornings — the season most repeat travellers choose.

First serious snow at Sela usually arrives between the second and fourth week. Tawang town: −4°C to 8°C. Clear blue days between snow events. Bumla starts closing intermittently. Pack for genuine cold: this is the month people most often underestimate.

Weather rarely cancels a Tawang trip; it reorders it. A snow day at Sela means you sleep an extra night in Dirang and shift Bumla to the following morning. A landslide in the gorge means a late arrival, not a lost day. Building one buffer night into a six- or seven-day plan absorbs almost everything the mountain throws at you.
