Victoria 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.

Large areas of southern Australia can expect a foggy start to the next few mornings, reducing visibility for the first few hours, even in the southeastern capitals.
The strongest southeasterly wind surge since last Dry Season has swept out any lingering sticky humidity from the summer over a large swathe of the central and eastern tropics.
