Since China is such a large country, climate and temperature change drastically from region to region. Sub-tropical Hong Kong is going to have much different weather than the steppes of Inner Mongolia or the mountain ranges of Tibet and Western China.

Summers in China (June-August) is the peak time to visit, though it also the hottest time. Temperatures will soar into the 30s (87-92 F) and can get quite humid. The pollution and air quality can also be ongoing concerns during this time. Expect inflated prices and larger crowds during these months.

September-October is a great time to visit China, as long as you can dodge the hectic Golden Week holiday in early October. The weather will cool to just under 20C (68 F), which is much more pleasant for hiking and exploring.

Traveling to China in the winter is rare, unless you’re heading to Hong Kong where the weather is still pleasant at 20C (68 F). Places like the Great Wall are occasionally closed due to weather, and regions like Tibet can drop to -13 C (9F) overnight. That being said, China has a fun winter festival called the Harbin Ice and Snow Festival where you’ll find huge, record-breaking ice sculptures.
