Aalo in June
Arunachal Pradesh, India
Siang River floods cut road access for weeks during monsoon season
June in Aalo is the wettest stretch of the West Siang year. Monthly rainfall sits at 600-800mm, often delivered as 12-hour deluges that knock landslides across NH-13 and the Aalo-Tato-Mechuka stretch alike. Daytime 23-29C, nights 19-22C, but the wet-bulb temperature makes outdoor walking unpleasant. The Yomgo runs at flood-stage. Most homestays in surrounding villages (Hege, Karbak, Bagra) close to non-resident guests as families focus on rice transplantation and home-roof repairs. Aalo town's grid takes power-cut hits 4-6 hours daily. The Pasighat-Aalo bus runs but cancellations are common; the road from Likabali develops gully-washouts every 15-20 days. There is no version of the trip that works in June. Wait for late October.
