Marine Heat Waves (MHWs) — periods of abnormally high sea surface temperatures lasting several days — are becoming more frequent and intense under climate change. Enhancing our capacity to monitor and predict them is now crucial — not only for science, but also for society and ocean health.

The event gathers 25 experts from 11 countries to exchange insights and shape future research around four core objectives: improving MHW detection, enhancing observability, advancing predictability, and assessing impacts. A major outcome will be a White Paper summarizing key challenges and opportunities and outlining a roadmap for future MHW-related activities.
