Annual Water Temperature Trend

Armstrong Beach sits on a quiet stretch of Queensland’s North Coast, looking out over the Coral Sea, and water temperatures here remain warm for most of the year. During summer, from around December to March, the sea usually holds between 27 and 29 °C, giving the water a very tropical feel that suits longer swims. In winter, typically June to August, temperatures ease back to about 22–24 °C, which is still mild and comfortable on clear, sunny days. Spring and autumn often deliver the best balance, with water temperatures commonly in the 24–26 °C range and more settled coastal weather.
