World Oceans and Western Europe Hit Record High Temperatures in July 2026

The world's oceans reached their hottest ever recorded temperatures for the month of July in 2026, according to new data released by the Copernicus Climate Change Service, which is implemented by the European Center for Medium-Range Weather Forecasts. The average sea surface temperature outside of the polar regions reached an astonishing 20.96 degrees Celsius last month. This figure easily surpasses the previous high of 20.89 degrees Celsius which had been set in July 2023. Globally, temperatures for July 2026 soared to 1.47 degrees Celsius above the estimated pre-industrial average for the month.

Alongside the marine heat records, western Europe experienced its hottest ever combined months of June and July. The average temperature across western Europe for this two-month period hit 21.62 degrees Celsius, which is a remarkable 2.79 degrees Celsius above the historical average for the region. Samantha Burgess, speaking on the prolonged extreme weather, noted that July 2026 was the third consecutive month of exceptional heat in western Europe. Burgess further emphasized that this situation serves as a clear example of how climate change is intensifying heat extremes, with heat and drought increasingly reinforcing one another.

The combination of extreme heat and a lack of rainfall has triggered severe environmental crises across the United Kingdom. England and Wales officially recorded their driest July in an astonishing 190 years of historical records. As a direct result of these severely parched conditions, large parts of England and the entirety of Wales have now been officially declared in drought by the Environment Agency. Adding context to the local impacts, the Met Office reported that the hottest day of the year in southern England is now on average 4.5 degrees Celsius warmer than the baseline period of 1961 to 1990, and overall temperatures are running 1.4 degrees Celsius warmer on average than the late 19th Century.

Reflecting on the broad spectrum of environmental pressures, Laurence Rouil of the Copernicus Atmosphere Monitoring Service addressed the escalating fire dangers. Rouil stated that climate change is increasingly bringing the kinds of hot and dry conditions that favour large, high-intensity wildfires in southern Europe while extending the fire season northwards. These compounding factors of agricultural drought, water restrictions, and rampant blazes continue to strain emergency responses across the continent during the ongoing summer season.

The cascading impacts of these global atmospheric and marine shifts have left climatologists warning about the permanent departure from historical weather norms. Mike Kendon of the Met Office highlighted the gravity of the current situation by declaring that we are right now living in a time of historic and unprecedented change. Kendon further stressed that concrete evidence shows the climate of the 20th century has now gone, underscoring the stark reality facing scientists, governments, and communities worldwide as they grapple with intensifying climate extremes.
