Water quality at 23 beaches has been rated 'good' and 10 'fair' for this weekend, unchanged from last week.

Seven beaches - Anglers', Approach, Ting Kau, Casam, Gemini, Hoi Mei Wan and Lido - are closed to swimmers year round because of poor water quality. People should not swim at these beaches.

Bathers should avoid swimming at beaches for up to three days after a storm or heavy rainfall. Click here for the latest gradings.
