The Environmental Protection Department (EPD) today (April 12) released the latest grading of water quality for 39 gazetted beaches (see Note 1) and one non-gazetted beach (see Note 2).

Cafeteria New Beach Lower Cheung Sha Beach

Grade 2 beaches are:

Grade 4 beach is:

Compared with the grading released last week, Ting Kau Beach has been upgraded from Grade 2 to Grade 1. Butterfly Beach and Ma Wan Tung Wan Beach have been changed from Grade 1 to Grade 2, and Anglers' Beach from Grade 3 to Grade 4.

“We observed water quality deterioration at Anglers' Beach, which was largely due to the unstable weather early this week, and the lack of sunshine in the following days also impeded the beach water quality recovery. We will continue to closely monitor the beach water quality,” an EPD spokesman said.

Under the present grading system, beaches are classified into four grades, namely Good (Grade 1), Fair (Grade 2), Poor (Grade 3) and Very Poor (Grade 4), according to the level of E. coli in the water. Grades are calculated on the basis of the geometric mean of the E. coli counts on the five most recent sampling occasions.

While the ratings represent the general water quality at the beaches, the EPD spokesman reminded members of the public that water quality could be temporarily affected during and after periods of heavy rain. Bathers should avoid swimming at beaches for up to three days after a tropical cyclone or heavy rainfall.

A summary of beach grades is published weekly before the weekend. The latest beach grades based on the most current data may be obtained from the EPD's website on Beach Water Quality ( or the beach hotline, 2511 6666. Members of the public can also obtain the latest daily water quality forecast information for all beaches that are open for swimming through the Beach Water Quality Forecast mobile application (available for download from: or the dedicated beach water quality forecast page ( on the EPD's beach thematic website.
