Reliable summer rainfall forecasts in coastal northeast Australia can empower sugar cane growers to better manage their farm, including tailoring nitrogen applications for the coming climate, which will reduce damage to the Great Barrier Reef. We evaluated the ability of a seasonal climate forecasting model (ACCESS-S) to predict summer rainfall for the wet tropics region of northeastern Australia. We found that ACCESS-S was unable to capture the rainfall variability, primarily due to not being able to capture the extreme events.
