Central content

QimeiCimei's climate is heavily influenced by its general location. Penghu is situated near the Tropic of Cancer and its annual average temperature is 23°C. The lowest average temperature occurs in February at 16.2°C while the highest average temperature occurs in July with 28.3°C. Due to a lack of good ground cover, despite being surrounded by the sea it tends to become quite hot under the direct sun during the summer. Notwithstanding the breeze from the south, it still feels very hot and dry. When the powerful northeasterly winds blow in the winter, the wind-chill factor means it feels a lot colder than 7°C.


(1) Plant ecosystem
Gaillardia pulchella Climate and Ecology
The vegetation on Cimei generally appears in the form of grasslands or patches of grass. The plant species are generally the same as other offshore islands in Penghu being tufted grasses from the Poaceae family such as Goosegrass and Bermudagrass. The most common type of brushwood found on the island is the White Popinac.This can often be found in large standards. Other plants like the Seaside Clerodendron, Screw Pine, and Common Lantana are mainly found growing on the gravel slops near the seashore. The Yellow Maple and Indian Almond are the tallest trees found on Cimei. The former produces large, long-lasting blossoms while the latter turns red during the winter each year, giving Cimei a rather festive touch.

(2)Ocean ecosystem
Ocean ecosystemEcology
Cimei is located in the southeastern part of the Taiwan Strait. Its coastal environment is affected by the strength of the Kuroshio Current and other currents running along the Chinese coastline. With the Kuroshio Current in summer and the Chinese coastal currents in winter both passing through the area, this has given rise to a rich population of plankton and fish species. There are at least 145 families and over 700 species of fish found in the local waters. Most are from the Perciformes (class: Osteichthyes) order such as the Squalidae, Scombridae, Triplefins, Mullidae and Carangidae. Corals, soft corals, horn corals and coral polyps grown in abundance on the seabed.

Birds ecosystem
The flat, even terrain found on Cimei Island offers birds an excellent breeding ground. Most nest near Cimei Reservoir with the white egret, brown shrike and skylark population peaking in spring between January and April each year.
