Of four beaches open to the public, three have been rated "good" and one "fair" for this weekend, according to the Environmental Protection Department's latest grading. Other beaches have been closed for the winter season.

The three beaches rated "good" are Deep Water Bay, Clear Water Bay Second Beach and Golden Beach. Water quality at Silverstrand Beach is "fair".

Compared with last week's grading, Golden Beach's water quality has been upgraded from 'fair' to 'good'.

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.
