The Far South Coast of New South Wales stretches from around Bermagui to the Victorian border and is strongly influenced by cooler Tasman Sea conditions. Sea water temperatures here show clear seasonal changes and are generally cooler than along northern NSW. In summer, water temperatures typically range from about 18°C to 21°C, which can feel refreshing rather than warm. Autumn often remains pleasant, with temperatures around 17–20°C before cooling further in winter. During winter, sea water temperatures usually sit between 14°C and 16°C, feeling cold on entry and limiting time in the water for most swimmers. Spring brings a gradual warming trend, with temperatures rising back toward 16–19°C as summer approaches.
Swimming Conditions
Swimming is allowed throughout the Far South Coast and is enjoyed mainly during the warmer months, particularly in summer and early autumn when water temperatures are at their highest. Even then, swimming often suits shorter sessions, especially on cooler or windy days. In winter, swimming is far less common among casual beachgoers due to cold water, though it continues among surfers, ocean swimmers and experienced locals, most of whom wear wetsuits for comfort and safety. The region offers many clean, scenic beaches and sheltered bays that can provide calmer conditions when swell is present. Overall, the Far South Coast is best suited to confident swimmers and those comfortable with cooler water, offering rewarding swimming experiences during the warmer part of the year and striking coastal environments year-round.
