Hong Kong climate overview

Perched on the south coast of China in the Pearl River estuary lies the bustling city-state of Hong Kong with its atmospheric mix of oriental and western consumerism, and its towering skyscrapers. Once a colonial outpost of empire Hong Kong now falls within the jurisdiction of Beijing, but is still very much the international centre of Asia.

Hong Kong consists of a mainland peninsula and hundreds of islands. It is remarkably mountainous with several peaks over 800 metres (2,600 ft). Urban districts are densely populated but there are also significant areas of countryside, much of it now protected from development.

Before the arrival of the British in the mid nineteenth century the whole region had been largely deforested leaving bare hillsides which are still visible in places where replanting has not taken place. The mountains are largely volcanic with outcrops of granite on many slopes.

Lying just within the tropics Hong Kong experiences four distinct seasons. The climate is influenced in winter by the north-east monsoon and in summer by the south-west monsoon. Summers are hot and humid with a rainy season running from May to August and rainfall most persistent in May and June.

Winters are relatively dry with occasional windy cold spells as chilly air sweeps down from northern China. The months from February to April are particularly prone to low cloud, drizzle, and hill fog, and there is also a risk of typhoons from July to September.
