The climate is fairly warm tropical climates. Annual average temperature is about 20ºC (68ºF) and ranges from 16ºC (50ºF) to 25ºC (77ºF). Humidity levels are high and average values vary between 73% and 90%. Annual rainfall is 1.778mm, mostly during summer.

Autumn (October - December) is the most pleasant season. Days are sunny and warm and humidity levels are low. Winter (January - March) is cold but sunny. In April humidity increases and from May to September the climate becomes hot, humid and rainy with occasional tropical storms (typhoons).

Warning signals for typhoons depend on the proximity of a tropical storm. If the signal 8 is hoisted, the bridges between Macau and Taipa will be closed while the lower level of the Sai Van Bridge remains open, and as a preventive measure, sea and air connections between Macau and Hong Kong as well as most flights will also be cancelled.

In the summer, visitors are advised to wear light cotton clothes. In winter some woolen clothes are recommended as well as a thicker jacket or even an overcoat. From March to May as well as from September to November nights are cooler and therefore a cardigan or sweater will be useful.
