Swanbourne Beach sits between Cottesloe and City Beach along Perth’s City Coast, fronting the open Indian Ocean with a wide, natural stretch of sand and fewer crowds than its neighbours. Water temperatures here follow the familiar Perth pattern and are well suited to swimming for much of the year. In summer, from December to February, the sea usually ranges between 21–24°C, feeling warm and refreshing on hot days. Autumn stays comfortable at around 19–22°C, while winter cools to roughly 16–18°C, which is brisk but still manageable for shorter swims. Spring brings a steady warm-up again, generally sitting between 18–21°C as conditions improve.
