Annual Water Temperature Trend

Bermagui sits on the NSW south coast where the Tasman Sea produces relatively cool water year‑round compared with northern beaches. Sea temperatures typically range from about 13°C in the coldest part of winter to around 22°C at the height of late summer. More specifically, summer months commonly see water between 19°C and 22°C, autumn usually brings 17°C to 20°C, winter averages about 13°C to 16°C, and spring tends to warm from roughly 15°C to 18°C. Local conditions such as onshore winds, swell and distance from shore can cause short‑term variation, with nearshore rock pools and the protected harbour often feeling a little warmer than exposed surf beaches.
