New South Wales/ACT Sea Surface Temperature Anomalies
The sea surface temperature anomaly (SSTA) is the difference between the observed SST and the climatological SST. These anomalies are calculated on a weekly basis.
Positive SSTAs are usually correlated with increased regions of convection (cloudiness and rainfall) while negative SSTAs are usually correlated to reduced convection.
SSTAs can be used as an indicator of the phase of global climate fluctuations, such as the El Nino/Southern Oscillation (ENSO).
The data displayed in this map is the weekly average, centred on the date shown.
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.
As the mercury plummets across South Australia ahead of winter, coastal properties are preparing for the inevitable storm surges.
