Autumn often remains mild, with water temperatures commonly between 16–20 °C, while spring is cooler at roughly 14–18 °C as the ocean slowly warms after winter. During winter, water temperatures typically drop to about 11–14 °C, which is cold and usually limits swimming to short dips or those wearing wetsuits.
