Verified questions that cite this figure
How big is Hong Kong, and is it an island?
Hong Kong’s land area is about 1,114.6 km², made up of Hong Kong Island, Kowloon, the New Territories and over 260 islands. Hong Kong as a whole is not an island, though Hong Kong Island is — Kowloon and the New Territories are joined to the mainland.
When do typhoons hit Hong Kong?
Tropical cyclones can affect Hong Kong at any time of year but cluster in late summer and early autumn. In practice, what matters is the Observatory’s warning signal — 1, 3, 8, 9 or 10.
When is the fishing moratorium in Hong Kong?
Hong Kong has no statutory closed fishing season of its own. The summer moratorium belongs to the mainland’s South China Sea fisheries management; Hong Kong vessels are bound by it only when fishing in mainland waters. Locally, the key restrictions are the trawling ban and fisheries protection areas.
How big is Hong Kong? What is its land area in square kilometres?
At end-2025 the Census and Statistics Department recorded a land area of 1,114.6 km²: Hong Kong Island 80.7, Kowloon 46.9, and the New Territories and Islands 986.9. Reclamation increases the figure slightly every year, so the year-end reference date matters.
