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 the typhoons which depend upon the proximity of a tropical storm. If a signal 8 is hoisted, the bridges between Macau and Taipa and the isthmus between Taipa and Coloane are closed. As a preventive measure sea and air connections between Macau and Hong Kong as well as most flights are cancelled.
In 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.
