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.

A very wet weekend ahead for NSW

14:35 AEST Rainfall is set to intensify over the weekend and early next week, with hundreds of millimetres in just three days possible across parts of the central NSW coastline.  The heavy rainfall forecast at the end of this week will follow a prolonged period of rainfall which began on Tuesday, generated by a coastal trough lingering off the NSW coast for days.  Nord’s Wharf Oval in the Hunter Valley recorded 93mm in the 24 hours leading up to 9am Wednesday, May 5.
