July 2026 was the hottest month on record for global sea surface temperatures, while the Mediterranean reached its highest average July temperature recorded at 27°C.
Marine heatwaves covered about 90% of the Bay of Biscay–Iberian coast region and 80% of the western Mediterranean, with the study warning that further global warming would make similar extremes more intense and frequent.

Europe’s exceptional 2026 sea heat was not simply a product of natural variability, according to World Weather Attribution (WWA). Its analysis found that human-caused climate change was the main driver of record-breaking sea-surface temperatures around Europe, directly adding roughly 2°C of warming in the Mediterranean and more than 1.3–1.4°C in western European seas.
What the study found across Europe’s seas
The heat affected a wide area, including the Mediterranean, Bay of Biscay, Iberian waters, and the Celtic seas. In most of the regions examined, summer warming exceeded the approximately 1.4°C global-average warming level used in the analysis. Farther north, Celtic Sea temperatures were around 1.2°C above average, while parts of the Mediterranean were as much as 3°C above average.
The scale of the event was also visible in marine-heatwave coverage. About 90% of the Bay of Biscay–Iberian coast region and 80% of the western Mediterranean experienced marine-heatwave conditions.

What should I do next in practice?
Marine heatwaves covered about 90% of the Bay of Biscay–Iberian coast region and 80% of the western Mediterranean, with the study warning that further global warming would make similar extremes more intense and frequent.
July 2026 was reported as the month when the world’s seas reached their hottest surface temperature on record. Along Europe’s Atlantic coast and in the western Mediterranean, sea-surface temperatures reached record levels; Mediterranean waters were up to 6°C hotter than normal in June.
The Mediterranean’s average temperature reached 27°C in July, its highest recorded average for that month. An offshore buoy near Mallorca also measured 33°C in early August.
These observations describe the heat itself. The attribution result goes further: by combining observational data with climate-model simulations, WWA estimated how much human-caused warming contributed to the event.
Why marine heatwaves matter
Marine heatwaves can damage the organisms that create marine habitat, including corals, sponges, and macroalgae. Large-scale losses of these species can remove shelter and food sources, creating knock-on effects through food webs that reach invertebrates, fish, seabirds, and marine mammals.
Persistent warming can also make established habitats unsuitable for some species. Populations may shift northward, while warm-adapted organisms become more competitive. Those changes can alter marine communities and affect fisheries, aquaculture, and the fish and crustaceans available as food.
The reported ecological signals included an unusual increase in octopus around the United Kingdom and dolphins feeding on jellyfish as prey such as mackerel declined. More jellyfish and periods of low oxygen can also affect coastal tourism, including by contributing to beach closures.
Risks for coastal communities
Hotter seas can raise the temperature and humidity of nearby coastal air, particularly at night, adding to heat stress on land. Warmer water also increases evaporation, supplying more moisture to the atmosphere that can contribute to heavier rainfall when weather systems trigger it.
There are direct public-health concerns as well. Sustained warm seawater can increase the risk of water-borne infections such as vibriosis, while ecological disruption can affect the economies and food systems that depend on healthy coastal waters.
What another 1.4°C of warming would mean
WWA warned that an additional 1.4°C of global warming would make marine heat extremes such as this more intense and more frequent. The supplied findings do not provide a precise, region-by-region temperature projection for that scenario, so the clearest conclusion is about direction and risk: further warming would compound pressure on ecosystems, fisheries, food supplies, tourism, and coastal health.
The response researchers recommended
The study’s conclusion combines mitigation with adaptation. Rapidly reducing fossil-fuel emissions and limiting further global warming is essential to reduce the likelihood and severity of future marine heat extremes. At the same time, coastal communities and marine industries need adaptation measures that protect ecosystems, prepare fisheries for shifting species, and address heat, infection, and heavy-rainfall risks.
The central message is therefore both specific and broad: human-caused warming added a substantial amount of heat to Europe’s seas in 2026, and the resulting marine heatwave is not only an ocean-temperature record. It is a warning about the ecological and social consequences of allowing ocean warming to continue.
