The short answer
When to go to Ha Giang
The best window is October and November, when rain has eased, skies are clearer and buckwheat flowers colour the plateau; September and March to April are good alternatives. Avoid May to August, when heavy rain makes the mountain roads slippery and landslides can delay journeys. Winter is dry but cold on the plateau, with lows near 5 C. Note that the temperatures shown are for Ha Giang town, which sits much lower than the Dong Van plateau; expect it to be several degrees cooler up on the plateau. For older travellers, October and November give the most comfortable temperatures and the best views.
