September is the end of Summer when the rainfall start to drop down as well as temperature. An average day time temperature in September is at around 18C and at night temperature is at around 5C. For the first half of September you will still see the green color of the mountains and from around the second half the mountain starts to fade its green color. Rain and thunderstorm also happens in this season. Snow is probable at Yading Park at elevation over 4000 meters. In general September will have less rain than July and August but not definate. September is becoming autumn season but in reality often it is not autumn season yet. Sometimes September may feel worse than August because: A. It has the climate that the rain may be common so it can be wet like July and August; B. When it's wet, it's not always rain, it can be snow because it is colder than August and at high elevation it comes down as snow. When we say it may feel worse because the snow stay on the trails we walk, and the snow may stay for a couple of days hence the trail will stay muddy for a couple of days. And plus the foggy weather that the sun doesn't heat the trail enough, it's usually not comfortable walk on these trails. But this doesn't say September is not a better season to travel to Yading, on the contrary, it is one of the best seasons. The reasons are: A, less crowded; B, not cold yet still lower possibility of rain than summer.

November

November is an underestimated season to travel to Daocheng Yading. It could be a better season to travel to Yading than October. Day temperature of November by average is at around 12C and night temperature at around -5C. At Yading it can be 5C in the day and -10C at night. It looks cold but as long as you don't sleep at over 4000 meters it is managable because you only visit Yading in the day time by night time you will be sleeping indoors in hotels. When we say November could be a better season traveling to Yading than October is based on 2 facts. One is that it has much less visitors in November than in October. The other reason is it has even a higher chance of sunny days. From the former data we have an average of 18 sunny days in November and only 3 days of rainy by average. But obviously you would miss the "golden colors" of Yading but first half of November doesn't really so dreary after all. One issue though is the icy, that the road or trail may have ice after a snowfall.
