Hong Kong experiences four distinct seasons, with the climate influenced in winter by the north-northeast monsoon and in summer by the south-southwest monsoon. Summers are very hot, with the rainy season running from June to August. Spring and autumn are warm with occasional rain and cooler evenings. Winter can be cold, but most days are mild. There is a risk of typhoons and tropical storms from April to October, although direct hits are rare.

Lightweight clothing during warmer months, with warmer clothes for spring and autumn evenings. It should be noted that even during the hottest weather, a jacket or pullover will be required for the sometimes fierce air conditioning indoors. Warm mediumweights are best during winter. Waterproofing is advisable during summer rains.
