Annual Water Temperature Trend

Kiama, on the New South Wales South Coast, sits where the Tasman Sea meets a rugged shoreline of beaches, headlands and rock shelves. Sea temperatures around Kiama change through the year: in summer (December–February) surface waters typically reach about 20–23 °C, autumn averages fall to roughly 17–21 °C, winter (June–August) brings the coolest conditions at about 14–17 °C, and spring usually warms from roughly 16–19 °C. Localised conditions can vary with wind, swell and coastal upwelling, so short-term temperatures at beaches or in sheltered coves may differ slightly from these general seasonal ranges.
