Four beaches open to the public have been rated "good" for this weekend, according to the Environmental Protection Department's latest grading. Other beaches have been closed for the winter season.

The 'good' beaches are Deep Water Bay, Clear Water Bay Second Beach, Golden Beach and Silverstrand Beach.

As many beaches are likely to be more polluted than their grades suggest during and after periods of heavy rain, bathers are advised to avoid swimming at beaches for up to three days after a storm or heavy rainfall.
