Where’s good to swim today?
It’s really easy to find out before you head out. During summer, Environment Canterbury regularly monitors the water quality at more than 100 of our region’s favourite rivers, streams and beaches. This helps us to assess conditions, trends and public health risks. The grades are based on guidelines established by the Ministry for the Environment and the Ministry of Health.

Land, Air, Water Aotearoa's (LAWA)(external link) has a comprehensive online guide to help you know where’s good to swim. The site is updated weekly through summer, generally within 24 to 48 hours of sampling and just before the weekend.
Sites graded very good, good and fair are considered suitable for contact recreation such as swimming and kayaking. Those that are graded good or fair may not be suitable at times — for example, after heavy rainfall.
