South Australia 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.
The data displayed in this map is the weekly average, centred on the date shown.

Powerful south-westerly ground swell impacts Tasmania
13:39 EST
Very large, long period waves are making for treacherous conditions along the western and northern coastlines of Tasmania. A series of cold fronts, which have brought gusty winds and cold conditions to much of the southeast, generated these large waves over the last week. Intense south to south-westerly winds over the Southern Ocean directed towards Australia with these fronts built this powerful swell event with passage of each frontal system across an already active sea state. On Tasmania’s western coast, the Cape Sorell directional wave buoy captured some very large waves bringing dangerous surf.
