* Remark: Owing to operational needs, Kai Tak Runway Park automatic weather station was slightly relocated within the same site on 22 April 2022.

** Remark: The Tai Po AWS was relocated from Tai Po Conservation Studies Centre to Tai Po Yuen Chau Tsai Park on 1 April 2022. On the same day, the AWS name “Tai Po” was renamed to “Tai Po (Yuen Chau Tsai Park)” and the past data of “Tai Po” AWS can be found at the “Tai Po (Conservation Studies Centre)” in the table “Terminated Weather/Tide Station”.

*** Remark: The automatic wind station at Tap Mun East started operation on 6 July 2017, and replaced the automatic wind station at Tap Mun on the same day.
