Beaches in China

China has 14,500km of coastline but very few resort-grade beaches. The mainland's coast is mostly working coast — fishing harbours, container ports, industrial estates — with a handful of tourism enclaves. The exception is Hainan Island, which sits south of the Tropic of Cancer and gives China its only year-round tropical beach destination. Sanya at Hainan's southern tip is what most Chinese travellers mean by "beach holiday".

Beyond Hainan, the calculation flips. The Shandong coast (Qingdao, Weihai, Yantai) gives the strongest temperate-zone beach experience — water warm enough to swim June–September, plus city infrastructure of a fully developed second-tier metropolis. Beidaihe is the family-weekend escape from Beijing; Xiamen pairs beach time with treaty-port architecture; Shantou rewards travellers willing to spend half their visit in restaurants. These are not Phuket or Bali alternatives — the visit is the city plus the beach, not just the beach.

Practical seasonality: Hainan is best November to April (the rest of the year is too hot and humid, and August through September brings typhoon risk). The Shandong coast inverts — June through early September is the swimmable window; April–May and October are pleasant but cool. Xiamen and Shantou have year-round mild weather but are at peak typhoon risk July–September. The Hong Kong beaches (Sai Kung, Cheung Chau, Big Wave Bay) work in the same Hainan-style window — November to April.
