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.
Every morning this month, Canberra has dropped to below freezing, with plenty of cold days as well.
Over the last week, much of the southeast has been treated to cold, cloud-free nights with light winds.
There have been a few hiccups along the way but the school garden at St Francis' Primary School in Hughenden continues to grow despite the on-going drought.
