Tasmania Sea Surface Temperature
The sea surface temperature (SST) varies much more slowly than atmospheric temperatures due to the heat capacity of water. As such, the SSTs lag the atmospheric temperatures on a seasonal timescale by about 3 months. The lowest SSTs are usually observed in early Spring and the highest SSTs are observed in early Autumn.
In tropical regions, SSTs greater than 26°C are considered suitable for formation of tropical cyclones.

It's looking more likely that a tropical cyclone will cross the Queensland coast in the coming days.
A slow-moving tropical low has drenched the WA mining town of Port Hedland, which has received more than 270 millimetres of rain this week.
Authorities are preparing for a potential cyclone that could hit the north Queensland coast in coming days, as the Bureau of Meteorology (BOM) tracks a tropical low in the Coral Sea that is expected to strengthen.
