Hong Kong is a Special Administrative Region of China with its own immigration system. Entering Hong Kong does not count as entering mainland China.

Hong Kong also connects to Macau by ferry (about 1 hour on TurboJet from Sheung Wan) with separate immigration at both ends.

Subtropical monsoon climate. Typhoon season (June–October) is the primary disruption risk. The airport operates a T1/T3/T8 signal system and closes for Category T8 or above.
