The beach with an asterisk is a non-gazetted beach. All gazetted beaches are equipped with shark nets.

A summary of beach grades is published weekly before the weekend. Latest beach grades based on the most current data may be obtained from the department's website on Beach Water Quality or the beach hotline, 2511 6666.

Compared with the grading released last week, Clear Water Bay Second Beach, Golden Beach, Lo So Shing Beach, Lower Cheung Sha Beach and Silverstrand Beach have been upgraded from Grade 2 to 1. Hoi Mei Wan Beach has been changed from Grade 1 to 2.

"The changes are generally within the normal range of fluctuation of the bacteriological water quality of the beaches," an EPD spokesman said. "The grading of the Butterfly Beach has also improved from Grade 4 to 2, after its water quality recovered from the temporary deterioration largely due to heavy rain".

Noting that a recent oil spill has affected Shek O Beach in Southern District, and red tides have recently affected a number of beaches at various districts, the EPD spokesman advised the public to check the latest update from the Leisure and Cultural Services Department before swimming.

People are advised not to swim at the closed beaches.

Under our present grading system, beaches are classified into four grades 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.

Grade 4 is assigned to beaches whose last E.coli reading exceeded a threshold figure, irrespective of the geometric mean. Swimmers are advised to avoid these beaches until the water quality improves.

The EPD spokesman warned that many beaches were likely to be more polluted than their grades suggested during and after periods of heavy rain. Bathers should avoid swimming at beaches for up to three days after a storm or heavy rainfall.
