Annual Water Temperature Trend

Te Waewae Bay lies on the southern coast of the South Island in the Southland Region, opening to the Tasman Sea between Fiordland and Riverton. Sea temperatures here reflect the cooler southern latitude and exposure to open ocean conditions. In winter, from June to August, the water generally ranges between 9–12°C, which feels very cold and is usually only comfortable for hardy swimmers or those wearing full wetsuits. Through spring, temperatures gradually rise to around 11–14°C. Summer, from December to March, brings the mildest conditions, with sea temperatures commonly sitting between 14–17°C during settled spells. Early autumn can still see 13–15°C before cooling again as winter approaches.
