Macau has a sub-tropical climate with hot, humid summers (April-September) that can reach temperatures of 35C/95F. Winters are cool but short (January-March). Heavy rains from June to September make summer a less desirable time to visit. Clear, sunny days make October-November the best time to visit.
Like the rest of Southern China, Macao is subject to typhoons (tropical cyclones). Storms can occur anytime between May and December, but August and September are often peak months for the frequency of typhoons.
