     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 websites on Beach Water Quality ( or or the beach hotline, 2511 6666.

     Compared with the grading released last week, Cafeteria New Beach has been upgraded from Grade 3 to Grade 2. Shek O Beach has been changed from Grade 1 to 2. Approach Beach and Castle Peak Beach have been changed from Grade 2 to 3.

     "The changes are generally within the normal range of fluctuation of the bacteriological water quality of the beaches," an EPD spokesman said.

     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.

     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 2012". The report summarises the water quality of gazetted beaches in 2012 and is accessible at a dedicated website at and EPD's website at
