Coastal water quality

We conduct weekly and bi-weekly testing at 107 sites along our Atlantic and False Bay coastlines to determine the water quality at recreational beaches, tidal pools, and coastal monitoring points. Access the raw results and FAQs on coastal water quality below.

As of 18 November 2024, the City initiated a new coastal water quality sampling regime. Key recreational nodes are now sampled weekly, while all other sites are still sampled twice a month or in a few cases, monthly. The raw data is presented in the water quality report below.
