West Coast of Tasmania – Water Temperature Overview

This page provides information on West Coast of Tasmania locations where sea water temperature data is available, including current conditions, monthly ranges and historical records.

Current Water Temperature

17.0°C

average

17.2°C

maximum

The current water temperature in the West Coast of Tasmania today is 17°C. Thus, the average water temperature is about 17°C. This is cool water that may feel brisk on entry. Swimming is usually limited to short sessions, and prolonged stays can become uncomfortable without thermal protection. Many swimmers choose a wetsuit, especially for surfing or open-water swimming.

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 West Coast of Tasmania faces the open Southern Ocean and is one of the most exposed and remote coastal areas in Australia. Sea water temperatures here are cool year-round and show clear seasonal variation, shaped by strong ocean swells and frequent weather changes. During summer, sea water temperatures typically range from about 14°C to 17°C, which feels cold even on warm days. Autumn sees a gradual cooling to around 13–15°C before winter brings the coldest conditions. In winter, sea water temperatures usually sit between 11°C and 13°C, making the water very cold on entry. Spring brings only a slow and limited warming, with temperatures generally remaining in the low to mid-teens until late in the season.

Swimming Conditions

Swimming is allowed along Tasmania’s West Coast, but in practice it is uncommon and highly dependent on conditions. Even in summer, swimming is usually limited to brief dips rather than extended sessions, as cold water and strong swells can quickly become uncomfortable and challenging. Many beaches, such as those near Strahan, are long, open and fully exposed to ocean energy, which reduces safe swimming opportunities for casual beachgoers. In winter, swimming is generally unsuitable for most people due to cold water, rough seas and unpredictable weather. Any swimming outside peak summer typically requires wetsuits and experience in cold-water conditions. Overall, the West Coast of Tasmania is better known for its wild landscapes and dramatic coastline than for swimming, offering opportunities mainly for confident and well-prepared ocean users who choose calm weather and sheltered locations carefully.
