Annual Water Temperature Trend

Point Lonsdale sits right at the entrance to Port Phillip Bay, where the colder waters of Bass Strait meet the bay, and that has a big influence on local water temperatures. Through summer, sea temperatures usually sit around 17–20°C, which is cool by Australian standards but still swimmable on warm days, especially with a bit of sunshine and light winds. Autumn sees the water slowly dropping to about 15–18°C, while winter is noticeably brisk, often around 12–14°C. In spring, temperatures begin to recover, generally hovering between 13–16°C, though conditions can change quickly depending on weather and swell.
