Annual Water Temperature Trend

Flying Fish Cove is the main settlement and harbour on Christmas Island, set in the warm tropical waters of the eastern Indian Ocean. Unlike mainland Australia, the sea here stays consistently warm throughout the year. In the drier season, from around May to October, water temperatures usually sit between 26–27 °C, which feels comfortably warm for extended swimming. During the wetter months, from November to April, the ocean often warms slightly to around 27–28 °C. Seasonal changes are subtle, and there’s no true cold-water period, making the cove suitable for swimming in almost any month.
