Sea surface warming over time in Australia's southern oceans

This chart shows the annual sea surface temperature anomaly for Australia’s southern regions. Sea surface temperature anomaly is a measure of how much the temperature in a given year is different from the average temperature over the period 1961–1990

During a marine heatwave, some areas can be almost 3C warmer than they were 25 years ago

This map shows the average sea surface temperature in the summer of 1993-94, with an average across the whole region of 15.8C. This compares with an average of 18.4C for the summer of 2015-16
