The short answer
When to go to Tawang
September to November is the best window, prized for clear skies and the most comfortable cool temperatures, while December to February brings snow that has historically closed the route over Sela Pass. The new Sela Tunnel now offers more reliable, all-weather access to Tawang, though snow and cold still make winter travel harder going. April to August can bring mist, and July is the wettest month, with a real landslide risk on the long mountain drive from Guwahati.
