Shoulder seasons win for most first-timers
April–May and September–October are popular for milder weather in many classic cities. Summer is hot and humid in the east; winter is cold in Beijing but fewer crowds and lower hotel prices.
Holidays that change everything
Chinese New Year and National Day Golden Week mean crowded trains and attractions. If you must travel then, book everything early and lower your sightseeing ambitions.
City notes
Beijing winters are dry and cold; summers hot. Shanghai is humid. Chengdu is milder but gray/misty at times. Guilin/Yangshuo is lush with rain possible in warmer months — pack layers either way.
