Annual Water Temperature Trend

Ramsgate Beach lies along the western side of Botany Bay, where the water is influenced by the Tasman Sea but remains noticeably calmer than Sydney’s open surf beaches.

In summer, from December to March, the sea typically sits between 21–24 °C, offering comfortable conditions for swimming without needing a wetsuit. Autumn sees temperatures ease back to around 19–21 °C. Winter brings cooler water, usually in the 16–18 °C range, while spring marks a gradual warm-up to about 18–20 °C as the weather and water begin to lift again.
