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.
Icy and windy weather affecting parts of the NSW central-west and Blue Mountains will continue into tomorrow, although strong coastal winds are easing, the Bureau of Meteorology (BoM) says.
After a slow start to the snow season and a week of small to no surf, an intense cold front has brought some happiness to snowboarders and surfers in Victoria and New South Wales.
Parts of WA have been receiving persistent showers in recent days, propelling some locations well past their monthly average.
