Annual Water Temperature Trend

Tweed Heads sits right on the NSW–Queensland border and enjoys a mild, subtropical climate that keeps water temperatures fairly inviting for most of the year. In the Coral Sea off the local beaches, water temperatures typically range from about 20–22 °C in winter to around 25–27 °C through summer. Autumn often brings some of the most comfortable conditions, with the sea holding between 23–25 °C and calmer days common between weather systems. Spring starts cooler, usually around 21–23 °C, but temperatures climb steadily as summer approaches, making it easier to plan longer swims without the initial shock.
