The short answer
October to November and March to April are the most reliable months: dry roads, clear views, and comfortable temperatures. December to February is clear but cold at altitude; May to September is green but wet.
The two best windows
October and November offer the best combination of dry weather, clear skies, and comfortable temperatures. The summer rains have ended, the landscape is still green, and the mountain views are reliable. March and April are similar, with warmer days and spring flowers, though the south can be hot and hazy.
These windows are also popular. Book transport and accommodation ahead, especially around the National Day holiday in early October and the May Day holiday in early May.
Season by region
The northwest is best from October to November and March to May. Winter is cold but clear; summer is green but cloudy. The tropical south is best from November to April, when humidity and rain are lower. Yuanyang's terraces are best from December to March, when the paddies are flooded.
There is no single best month for the whole province. Match the season to the region you want to visit rather than trying to optimize for all of Yunnan.
The trade-offs
The rainy season is not a write-off. Landscapes are lush, crowds are thinner, and prices are lower. But roads can close, views can disappear, and outdoor plans can be cancelled. If you travel in summer, build flexibility into your itinerary and bring proper rain gear.
