The scienceWater quality information
LAWA shows the best available water quality information to help you to decide where to swim. The water quality of swimming sites in the Wellington region is determined by predictive models and water quality monitoring.
Predicted risk status

10:15 pm, 14 NovemberThe predicted risk status is updated hourly during the day so you can see the current water quality status for this site.
Reminder
Heavy rain flushes contaminants from urban and rural land into waterways and we advise you not to swim for 2 – 3 days after heavy or prolonged rain – even at sites that generally have good water quality. Check that the water is clean and clear before taking a dip.

This large sandy beach is located on Wellington's south coast. It is a popular surf, kite-boarding and swimming beach. The gentle slope of the beach allows bathers to get some distance out into the bay before getting out of their depth. The beach is generally safe for swimming and popular with families, but southerly swells can create dangerous waves. It is patrolled by lifeguards over summer weekends from early November to late March and all week during January. Parking is convenient all along the waterfront and a playground, changing facilities and toilets are located on the beach. This site is monitored as a part of Greater Wellington Regional Council’s Recreational Water Quality Monitoring Programme, which is specifically designed to inform the public about the suitability of various sites across the region for swimming and other recreational activities.
