## Geography

Dongji Island's village is located near the middle of the island in an area that was previously underwater. There are two mountains on the island- in the north is Hutoushan (虎頭山), in the south is Baguashan (八卦山). The smaller formerly inhabited Chutou Islet (Jotō-shō, Hotozan-to; 鋤頭嶼) is located to the immediate northwest of Dongji Island.
The marine area of Taijiang National Park covers a band extending 20 metres (66 ft) from the shore of Taiwan Island and 54 km (34 mi) long from Yanshui River to Dongji Island, an area of 344.05 km$^2$ (132.84 sq mi).

## Climate

Dongji Island has a tropical climate close to the humid subtropical boundary. Being an offshore island in the shallow Taiwan Strait, the location has lower diurnal temperature variation than either mainland Taiwan or the Asian continental landmass to its west. The island is also a lot drier and sunnier than the Taiwanese mainland. The vast majority of rain falls in summer as the East Asian monsoon penetrates the high-pressure systems otherwise dominating the area. Winters are dry with comfortable weather for outdoor activities, although cloudier than the low rainfall amounts would suggest.
