Annual Water Temperature Trend

The Whitsunday Islands sit off Queensland’s North Coast in the warm waters of the Coral Sea, and sea temperatures here stay inviting across the year. In summer, from roughly December to March, the water is typically around 27–29 °C, giving it a distinctly tropical feel that suits long swims and snorkelling sessions. During winter, usually June to August, temperatures ease back to about 22–24 °C, which is still mild and comfortable by Australian standards. Spring and autumn often provide the best balance, with water temperatures commonly ranging from 24–26 °C and generally calmer weather across the island group.
