Annual Water Temperature Trend

Cape Pillar marks one of the most exposed points on Tasmania’s east coast, rising straight out of the Tasman Sea where deep water and powerful swells dominate the conditions. Sea temperatures here stay cool year-round and can feel colder than elsewhere due to constant wave action and wind. In summer, from December to February, the water typically sits around 15–17 °C, which is brisk even on warm days. Autumn brings a gradual cooling to about 14–16 °C, while winter is distinctly cold, usually around 11–13 °C. During spring, temperatures slowly lift again, generally ranging between 13–15 °C as daylight increases, though conditions often remain unsettled.
