Quick Summary

European seas experienced their hottest summer on record in 2026, with an average temperature of 21.6°C between June and August, marking a significant increase from previous decades. The Bay of Biscay saw particularly high temperatures, surpassing the long-term average by more than 2.4°C and recording 186 marine heatwave days. This warming trend has led to dramatic changes in marine ecosystems, such as the near-total disappearance of kelp forests off the coast of Asturias, Spain, which provide vital habitats for various species. Concurrently, warmer waters have caused a surge in common octopus populations along southern England’s coastline, with landings increasing from less than 30 tonnes annually before 2025 to over 3,000 tonnes in 2026, illustrating how climate change is reshaping marine life and fisheries across Europe.

Story summary

European waters recorded their hottest summer on record in 2023, with an average temperature of 21.6°C between June and August, surpassing a 45-year historical dataset that dates back to 1982. The warming was especially notable in the Bay of Biscay, where temperatures reached 21.4°C, marking a significant increase of more than 2.4°C above the average from 1991-2020. This prolonged warmth caused 186 marine heatwave days by August's end.

In Asturias, northern Spain, large brown kelp forests have declined drastically, with about 95 percent of sampled stands disappearing since 2010, according to marine ecologist Jose Manuel Rico Ordas. Kelp provides crucial habitat and food for numerous marine species, making its decline particularly concerning for the ecosystem's health.

Narrative

The warming has been particularly pronounced in the Bay of Biscay, a part of the northeastern Atlantic Ocean along the western coasts of France and northern Spain, where average sea temperatures reached 21.4°C during the summer, more than 2.4°C above the 1991-2020 average.

Claims (15 extracted, 4 hedged)

With European waters recording their hottest summer on record, rising ocean temperatures are affecting marine life across the continent, damaging habitats and forcing several species into new waters. asserted

temperatures → record → waters

According to a Reuters analysis, European waters averaged 21.6°C between June and August, the highest summer average in a 45-year record dating back to 1982. uncertain

waters → accord → 1982

temperatures → pronounce → average

The region also recorded 186 marine heatwave days by the end of August, highlighting the prolonged nature of the unusually warm conditions. asserted

region → record → conditions

The prolonged warming is also affecting marine habitats. asserted

warming → prolong → habitats

Along the coast of Asturias in northern Spain, large brown kelp forests have declined sharply, with marine ecologist Jose Manuel Rico Ordas estimating that around 95 percent of the kelp stands sampled since 2010 have disappeared, according to Reuters. uncertain

percent → decline → Reuters

The loss of kelp is significant because the underwater forests provide food and shelter for several marine species, including sea urchins, lobsters and crayfish. asserted

forests → provide → urchins

As waters warm, species that depend on cooler conditions can come under pressure, while warmer-water species are increasingly moving into areas where they were previously less common. asserted

they → warm → areas

One of the clearest examples is emerging in southern England, where common octopus populations have surged as waters warm. asserted

waters → emerge → England

Octopus landings, which were below 30 tonnes a year before 2025, rose to around 2,600 tonnes in 2025 and have crossed 3,000 tonnes in 2026, according to figures cited by Reuters. uncertain

which → rise → Reuters

The shift in marine life is also changing the catch for fishermen. asserted

shift → change → fishermen

While some are benefiting from the sudden rise in octopus, others are seeing traditional catches such as crab, lobster and scallops decline, showing how warmer waters are reshaping Europe's fisheries. asserted

waters → benefit → fisheries

In the Mediterranean, warmer conditions are helping non-native species expand into new areas, adding to existing pressures on native marine life and changing local food chains. asserted

species → help → chains

Scientists say the changes are being driven by more frequent and intense marine heatwaves, which can affect the survival, reproduction and movement of marine species. asserted

which → say → species

As ocean temperatures continue to rise, species adapted to cooler waters may face increasing pressure, while warmer-water species can expand into new habitats. uncertain

species → continue → habitats
