Annual Water Temperature Trend

The Pass sits at the northern end of Clarkes Beach beneath Cape Byron, where the Coral Sea meets a naturally sheltered bay. Water temperatures here reflect the warm subtropical climate of northern New South Wales and stay comfortable for swimming through much of the year. In summer, the sea typically reaches around 25–27 °C, making the water inviting for extended swims. Autumn often holds onto that warmth, with temperatures commonly between 23–25 °C and generally settled conditions. Spring begins cooler at roughly 21–23 °C before steadily warming toward summer. Winter is the coolest season, but even then the water usually remains around 19–21 °C, which many locals still find swimmable on clear, sunny days.
