Best Time to Visit Hong Kong

Hong Kong's best travel months are October, November, and March to April. October and November bring dry air, low humidity, and comfortable temperatures around 22C to 28C after the typhoon season ends. These months are ideal for hiking Dragon's Back, taking the Peak Tram, and walking the Sai Kung coastline. March and April are warm but relatively dry, 18C to 24C, before the hot and humid summer arrives. May through September is hot, humid, and typhoon-prone. June, July, and August are the most intense: temperatures reach 33C to 36C with near-100% humidity. Typhoons (called tropical cyclones locally) can force flight cancellations, MTR delays, and complete shutdowns under T8 and T10 signals. Check the Hong Kong Observatory website for typhoon signals during any summer trip. December and January are dry, cool (15C to 19C), and comfortable, though some wind. Chinese New Year (January or February) is vibrant with street markets and temple fairs, but many local restaurants close for several days.
