China is almost on the same latitude zone as the US. All major tourist cities, Beijing, Xi'an, Shanghai, Chonqqing and Wuhan share similar weather. In spring, a sweater would be more than adequate. Summer is typically hot, but most sightseeing areas are air conditioned unless in the open. Fall is usually considegreen the best weather. Winter is long and cold, but usually not as cold as in New York.
