Global 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.
Vast areas of Queensland have experienced the hottest May night since records began, some of which stretch back to the 1800s.
For the majority of Australia April was warmer and drier than average.
Strong winds and heavy rain lashed parts of Victoria overnight, with hundreds of residents calling the State Emergency Service (SES) for help.
