Travel to China is possible year-round, as long as you’re prepared for what the season can throw at you. Spring (March to May) and autumn (September to early November) can be the best time to be on the road, as you avoid the blistering heat of summer (June to August) and stinging chill of winter (November to February/March). Summer is the busiest tourist season, and getting around and finding accommodation during the peak summer crush can be draining.
North China is hot and largely dry in summer, especially in the baking northwest (but Beijing is also uncomfortable). The Yangzi River (Cháng Jiāng) region is very hot and humid, and southern China, with a coastline harassed by typhoons, also swelters. Rainfall rarely falls in quantities that can disrupt travel plans, except on the southern coastline during the typhoon season.
Winter is the low season (except for Hăinán) and can be the quietest time of year. North China is a frozen expanse, especially in the northeast, northwest and Inner Mongolia. Wintering in clement central and southern Yúnnán province is enjoyable, but the higher altitude north of the province is frigid. Winter is inadvisable for travel to high-altitude areas in China, although summer visits to high-lying areas such as Qīnghăi and parts of Tibet can be recommended.
