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 and Golden. Water quality at Silverstrand Beach remains "fair".

Compared with last week's grading, there was no change in the grading of the four beaches.

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.
