  • Strengthened content for "Tidal Information" webpage

  • Thursday, 18th July 2019

The Hong Kong Observatory today (18th July 2019) strengthened the content of the "Tidal Information" webpage with the addition of selectable display of extreme water levels recorded during the passage of tropical cyclones in the past on the time series charts of the tide gauge stations. The added information serves to enhance the public's impression of the significant storm surges that have occurred in Hong Kong, and allow them to compare with the currently observed water levels. Depending on the operation period of the stations and completeness of relevant records, the available tropical cyclone records include those from Mangkhut in 2018, Hato in 2017, Hagupit in 2008 and Wanda in 1962.

The URL of the "Tidal Information" webpage is https://www.weather.gov.hk/tide/marine/realtide.htm.
