April: Warm Days Before the Rain

The sweet spot

April is often the best all-round month for the central and northwest routes. Days are warm, nights are cool, and the roads are dry. Lijiang and Shangri-La are increasingly comfortable, though the plateau still cools down sharply after sunset. Dali is windy but bright.

The tropical south is hot, and the burning season may still affect air quality. If you go, plan activities for early morning and late afternoon. The first rains usually arrive in May, bringing relief but also humidity.

Seasonal highlights

Spring flowers are visible at lower and mid altitudes. The terraces at Yuanyang are transitioning out of their flooded season, so check before planning a photography trip. Tiger Leaping Gorge is usually dry and clear, though heat on the exposed sections is a factor.

The May Day holiday can begin in the last days of April, bringing domestic crowds. Book transport and accommodation early if your dates overlap. The week after the holiday is often quieter.

Practical notes

Carry sun protection, water, and a light rain shell for pre-monsoon storms. In the northwest, a warm layer for evenings. In the south, breathable clothing and insect repellent. If you are hiking, start early to avoid the afternoon heat.
