New South Wales/ACT 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.

'Godzilla El Nino' intensifying: Drought, heatwaves and heightened bushfire risk expected this summer
With Australia in the grip of an extreme El Nino weather event, more heatwaves and a heightened bushfire risk are expected this summer.
Adelaide has recorded one of its hottest October days in 70 years, with the temperature reaching 35.6 degrees Celsius, as Country Fire Service (CFS) crews battle blazes across the state.
Monday was the earliest October day to surpass 30 degrees Celsius in Canberra since records began in 1939.
