The Open Day will be held at the Observatory Headquarters at 134A Nathan Road, Kowloon on November 26 and 27. The exhibitions at the Open Day will showcase how the HKO applies the latest technology to provide various services including weather forecasting, aviation weather services, microclimate monitoring and radiation monitoring.

With the theme “Early Warning and Early Action. Hydrometeorological and Climate Information for Disaster Risk Reduction”, the weather watchdog said it aims to raise public awareness of the risks associated with extreme weather under climate change, and encourage all to exercise early preparatory actions and contribute to disaster reduction.

Six sessions of visits will be provided each day. The duration of each session is around one hour.

Online pre-registration is required for the Open Day. Each applicant may request a maximum of four tickets free of charge. If the number of applications exceeds the capacity, admission tickets will be allotted through computer balloting.

The online registration system will accept applications starting today to noon on November 8.

Successful applicants will receive tickets with a QR code through email on or before November 21.
