Australian MHW forecasts
Forecasts of marine heatwave conditions are generated for each region of Australia illustrated in the map. The Gulf of Carpentaria cannot be forecast as this region is not well represented in the input data.
Each of the plots below shows the seasonal MHW threshold (red line). The recent observed temperature (black) and threshold for a marine heatwave index for the box (red) can be compared to the forecast temperature for the region (blue). Where the blue line exceeds the red line, we forecast MHWs for the month.
