North Coast of Tasmania – Water Temperature Overview
This page provides information on North Coast of Tasmania locations where sea water temperature data is available, including current conditions, monthly ranges and historical records.
Current Water Temperature
The current water temperature in the North Coast of Tasmania today is within the range of 18-19°C. Thus, the average water temperature is about 18°C. Water in this range feels cool but still manageable for many swimmers. Short to moderate swims are comfortable, especially in warm weather. Some people may prefer a wetsuit for longer stays, particularly when swimming actively or outside peak summer conditions.
It’s important to note that these swimming tips and recommendations apply only in settled weather. When air temperatures drop below 20°C — and sometimes even below 25°C — swimming can feel uncomfortable, even when water temperatures are relatively high.

The North Coast of Tasmania faces Bass Strait and experiences cooler sea water temperatures than mainland Australia, with clear seasonal variation. During summer, sea water temperatures typically range from about 15°C to 18°C, which can feel refreshing rather than warm. These are the most favourable conditions of the year for swimming. In autumn, temperatures gradually fall to around 14–16°C before reaching their lowest levels in winter. Winter sea water temperatures generally sit between 11°C and 13°C, making the water feel very cold on entry and limiting time in the sea for most people. Spring brings a slow warming trend, with temperatures rising back toward 13–15°C as summer approaches.
Swimming Conditions
Swimming is allowed along Tasmania’s North Coast, but it is strongly seasonal and suited mainly to the warmer months. Summer offers the best opportunities for swimming, particularly on calm days when air temperatures are higher and conditions are more settled. Even then, many swims tend to be short due to the cool water, especially for casual swimmers. In winter and early spring, swimming is generally limited to experienced ocean swimmers and surfers, most of whom wear wetsuits to manage the cold. The coastline features sandy beaches, small bays and river mouths that can provide more sheltered conditions than exposed headlands. Overall, the North Coast of Tasmania offers scenic and rewarding swimming experiences for those comfortable with cooler water, with the most accessible conditions occurring during the height of summer when sea temperatures are at their warmest.
