Sea temperatures reach their highest levels in July… amid heat waves and droughts ravaging Europe

Sea temperatures during July 2026 recorded unprecedented levels, after the average global sea surface temperature outside the polar regions reached the highest level recorded for this month, exceeding the previous record recorded in July 2023. This came in conjunction with severe heat waves that struck Western Europe, igniting widespread fires, and deepening the drought crisis in a number of countries.

Data released by the European Union’s Copernicus Climate Change Service reveal a picture beyond just warming water. Rising sea temperatures have coincided with exceptional air temperatures, declining soil moisture and river flows, and pressures on agriculture, water supply and production.Energy, which reflects the interconnectedness of the effects of warming in one system.

New record number

Sea surface temperatures during July recorded record levels on the Atlantic coast and the western Mediterranean, amid severe marine heat waves that affected the waters surrounding Europe.

Globally, average sea temperatures outside the cold polar regions reached the highest level on record for any month of July, surpassing the previous record dating back to 2023.

As for global surface air temperatures during July 2026, they were lower than July 2024 by a small difference of only 0.01 degrees Celsius, which prompted scientists to consider the two months to be in close rank as the second warmest July on record.

This record convergence puts the continuation of global warming in the spotlight,Especially with the coincidence of high temperatures in the water and land during the same season.

Europe under the heat

Western Europe had its warmest June and July on record, while the average temperature during the first two months of summer 2026 rose about 2.79 degrees Celsius above normal, surpassing the previous record set four years ago.

Climatologists described these conditions as reflecting an exceptional continuation of heat since the beginning of the season, while some Central European countries, including Austria and Slovakia, recorded record national temperatures.

The high sea temperatures coincided with repeated heat waves that have struck Europe since the end of spring, amid continued warming linked to fossil fuel emissions, as the late June wave reached a severe level, with…Estimates indicate that it is associated with more than 10,000 deaths.

These developments show how warming is turning from a number in the climate records to a factor that puts pressure on health, agriculture, energy and water at the same time.

Drought compounds the crisis

Persistent high-pressure systems played a key role in trapping heat over western Europe, while drought contributed to enhancing their effect.

Samantha Burgess, a climate scientist at the European Center for Medium-Range Weather Forecasts, explains that soil dryness reduces its natural ability to cool the air, which allows heat to accumulate faster and promotes the persistence of extreme conditions.

Large areas of France, Spain, and parts of Germany and the United Kingdom recorded low levelsExceptionally low rainfall and soil moisture occur during May and June, before conditions worsen in July.

The rise in sea temperatures and these phenomena are linked to the thirteenth goal of the Sustainable Development Goals (SDGs) on climate action, especially goal 13.1, which calls for enhancing resilience and adaptation to climate-related risks and natural disasters.

Water and energy are affected

The impact of drought was clearly evident in reduced river flows, putting pressure on water supplies, irrigation and energy production in several European regions.

In some countries, the crisis has reached power plants that rely on water for cooling. Two coal-fired plants in Poland were forced to shut down due to a lack of cooling water, and a nuclear power plant also stoppedThe only one in Hungary for the first time in its 44-year history.

These cases reveal how rising temperatures and water shortages can quickly move from the natural environment to infrastructure and the economy.

With sea temperatures continuing at high levels, the importance of monitoring changes in the water cycle and accompanying weather phenomena is increasing, especially in areas that depend on rivers and surface water to operate vital sectors.

Losses in billions of euros

Heat and drought are among the biggest environmental threats to the European economy, and the losses have already begun to appear this summer. Preliminary estimates indicate that the heat wave in June cost grain farmers about two billion euros as a result of crop losses.

But previous experiments show that the effectThe economic impact of drought may extend for years. A recent study concluded that the major drought that struck Europe between 2015 and 2018 cost the continent about 439 billion euros.

The study showed that agriculture is often exposed to large and rapid shocks, while sectors such as manufacturing and construction show losses that are less severe initially but may last longer.

This means that calculating losses of sea heat, heat, and drought over one season may provide an incomplete picture, because the cumulative effects extend to investment, production, and supply chains after the phenomenon itself ends.

Fires complete the circle

Since the beginning of the year, about 1.19 million acres have burned in European Union countries, with higher-than-average pollution levels resulting from thick smoke from burning vegetation.

Heat, drought, and winds also helped create conditions more suitable for the spread of fires, as fire severity indicators recorded record levels for this time of the year.

Forest management specialists believe that climate change provides more suitable conditions for the outbreak of huge fires, while vegetation management and urban planning can mitigate a large part of the risks.

An interconnected crisis

July data reveal that warming in Europe is moving along more than one path at the same time; Rising water temperatures coincide with atmospheric heat waves, drought weakens the soil’s ability to cool, and reduced water pressures agriculture and energy, while dry conditions create more flammable ground.

In this regard, The Earth Guards Foundation confirms The persistence of sea temperatures at record levels reinforces the need for climate policies that view these impacts as interconnected parts of a single crisis, while investing in adaptation, water management, protecting marine systems, and reducing fire risks.

The new records are now directly linked to human, economic and environmental costs, while Europe’s ability to face the coming seasons will be determined by how quickly these indicators are transformed into more resilient plans.
