Annual Water Temperature Trend

Remarkable Cave sits on the exposed edge of the Tasman Peninsula, facing the open Tasman Sea, where the water is clear, powerful, and consistently cool. Sea temperatures here follow the typical east coast Tasmanian pattern but can feel colder due to constant swell and wind. In summer, from December to February, the water usually reaches around 15–17 °C, which is refreshing rather than warm. Autumn sees a gradual cooling to about 14–16 °C, while winter is much colder, commonly around 11–13 °C. During spring, temperatures slowly rise again, generally sitting between 13–15 °C as daylight increases, though conditions often remain unsettled.
