Western Australia North 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.

Perth is enjoying a warm and dry end to what has otherwise wet and relatively cool summer.
Some $140 million will be spent on flood mitigation in Adelaide's inner-south and south-west over the next 20 years after an agreement between the State Government and five local councils.
