The 2024-25 summer was also the second year in a row that scientists from CSIRO and the Bureau of Meteorology delivered trial seasonal forecasts at national marine climate briefings as part of the Marine Heatwave Prediction Project.

The briefings are designed to help prepare researchers and governments for possible marine heatwave (MHW) emergence and impacts, supported by Fisheries Research and Development Corporation and the Department of Climate Change, Energy, the Environment and Water.

The long-range marine heatwave outlook will now be a regular fixture over the summer with forecasts made available publicly leading into and throughout the 2025-26 summer season. These forecasts will provide up to three months’ advance warning of ocean temperature extremes and the likelihood and location of marine heatwaves.
