Compared with last week, water quality at Clear Water Bay First Beach was upgraded from fair to good, and Ma Wan Tung Wan Beach was upgraded from poor to fair. Pui O Beach was downgraded from good to fair.

Seven gazetted beaches - Anglers', Approach, Ting Kau, Casam, Gemini, Hoi Mei Wan and Lido - are closed to swimmers year-round because of poor water quality.

Many beaches are likely to be more polluted than their grades suggest during and after heavy rain. Bathers should avoid swimming at beaches for up to three days after a storm or heavy rainfall.
