Answer

What does a marine heatwave mean for Mallorca?

A marine heatwave means sea temperatures stay unusually high for an extended period, rather than just spiking for a day or two. Around Mallorca, that can stress Posidonia seagrass, benthic species and fish that depend on stable water conditions. Repeated heatwaves can also disrupt the food chain and make recovery harder after hot summers.
