The Environmental Protection Department (EPD) today (April 15) released the latest grading of water quality for 39 beaches.
Seventeen beaches were rated as Good (Grade 1), 20 as Fair (Grade 2), one as Poor (Grade 3) and one as Very Poor (Grade 4).
Grade 1 beaches are:
Cheung Chau Tung Wan Beach Pui O Beach
Chung Hom Kok Beach Repulse Bay Beach
Clear Water Bay Second Beach South Bay Beach
Deep Water Bay Beach St Stephen's Beach

Grade 3 beach is:

Grade 4 beach is:

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. The latest beach grades based on the most current data may be obtained from the department's websites on Beach Water Quality (www.beachwq.gov.hk and www.epd.gov.hk/epd/beach) or the beach hotline, 2511 6666.
Compared with the grading released last week, Cafeteria New Beach, Casam Beach, Clear Water Bay First Beach, Kiu Tsui Beach, Lido Beach, Lower Cheung Sha Beach and Trio Beach have been changed from Grade 1 to Grade 2, Castle Peak Beach from Grade 2 to Grade 3, and Silver Mine Bay Beach from Grade 2 to Grade 4.
"The changes are generally within the normal range of fluctuation of the bacteriological water quality of the beaches. The very poor water quality of Silver Mine Bay Beach may be due to the recent heavy rainfall," the EPD spokesman said.
Noting that a suspected red tide has recently affected Hap Mun Bay Beach in Sai Kung District, the EPD spokesman advised the public to check the latest update from the Leisure and Cultural Services Department before swimming.
Under the 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.
People are advised not to swim at the closed beaches.
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.
Meanwhile, the department has published a report entitled "Beach Water Quality in Hong Kong 2015". The report summarises the water quality of gazetted beaches in 2015 and is accessible online at www.beachwq.gov.hk and www.epd.gov.hk.
