Hong Kong Observatory Open Day 2025

25 March 2025

Hong Kong Observatory (HKO) Open Day 2025 was successfully held on March 22nd and 23th. The public response was overwhelming, with close to 10,000 visitors attending the event.

The Open Day adopted the theme of the World Meteorological Day this year, “Closing the Early Warning Gap Together”, echoing the United Nations’ “Early Warnings for All” initiative. It is hoped that everyone can be protected by early warning systems, enabling them to respond promptly to extreme weather and minimise the impact brought by the increasingly severe natural disasters such as floods, heatwaves, and storms.

The Open Day featured exhibitions and games, attracting active participation from visitors. Through the event, they learned about the Observatory's efforts in collaborating with meteorological authorities around the world over the years and leveraging the latest technology to provide various services to the public. Visitors also gained a deeper understanding of the impacts of climate change and extreme weather.

During the Open Day, HKO staff interacted enthusiastically with the public and introduced the Observatory's work thoroughly. There were also live demonstrations of weather reporting, as well as the special appearance of Dr Tin, the Observatory's Mascot, for photo taking with visitors.

Besides HKO colleagues, over 70 volunteers from "Friends of the Observatory" acted as goodwill ambassadors to greet the visitors, contributing to the smooth operation of the 2-day event.
