Water Temperature in New South Wales: General Trends and Swimming Opportunities

During the summer months (December to February), sea temperatures along the eastern coast typically range from 70°F to 77°F (21°C to 25°C), providing ideal conditions for swimming, surfing, and other water activities. These warmer waters are especially welcoming for beachgoers, with areas like Bondi Beach in Sydney seeing consistent temperatures around 75°F (24°C) during the peak of summer.
