Ocean temperatures reach historic high in July 2026

According to the European Union's Copernicus Climate Change Service (C3S), global oceans recorded the highest average surface temperature ever documented for the month of July, reaching 20.96°C. This new record was reported on Monday, August 10, 2026, in a monthly report that highlights the occurrence of extreme weather phenomena due to El Niño.

The cyclical natural phenomenon known as El Niño has contributed to these record temperatures, intensifying climatic anomalies in various regions around the world. The situation is particularly critical in Western Europe, where July was marked by extreme heat, droughts, and wildfires.

Copernicus data indicate that July 2026 was not only one of the hottest Julys ever recorded globally, but also that the combination of hot and dry conditions exacerbated wildfires in Europe. These extreme climatic conditions have been linked to marine heatwaves affecting the Atlantic and Mediterranean oceans.

Moreover, the report mentions a series of impacts on Europe's climate, including an increase in the intensity of heatwaves. The conditions of heat and drought have worsened the wildfire situation, which has become increasingly frequent in recent years.

Copernicus emphasizes that this temperature record serves as a warning about the impact of climate change. The data indicate a rising trend of record temperatures, raising concerns about the consequences for marine and coastal ecosystems, as well as for local communities.

While the El Niño phenomenon has significantly contributed to this temperature increase, other climatic and environmental factors may also be playing a role in this extreme situation. The analysis by Copernicus serves as an important indicator of the global climate situation, with warnings about potential medium- and long-term consequences.
