Western Europe recorded its hottest first two months of summer on record during June and July 2026, according to the European Union’s climate monitor [1].
The record-breaking heat signals an intensifying trend of extreme weather that threatens public health, agriculture, and regional stability across the continent.
Copernicus, the EU's climate monitor, said Monday that the average temperature for June and July was 21.62 degrees Celsius (70.9 Fahrenheit) [1, 3]. This figure represents a temperature anomaly of approximately 2.79 degrees Celsius above the long-term average [3].
The heat was felt most acutely in regions home to 900 million people, who experienced their hottest July on record [2]. In Spain, the heatwave reached a peak temperature of 46 degrees Celsius [4].
These conditions created a volatile environment for wildfires. In Turkey, the resulting blazes forced 50,000 people to flee their homes [4]. Similar devastating wildfires affected populations across France, and Portugal as dry conditions persisted throughout the early summer [1, 4].
Climate change is the primary driver of these intense summer temperatures, which lead to the prolonged dry conditions necessary for large-scale fires [1, 2]. The current data suggests that the baseline for summer heat in Western Europe is shifting upward, increasing the frequency of these extreme events.

The breach of historical temperature records in Western Europe underscores the accelerating impact of global warming on temperate zones. When average temperatures deviate by nearly 3 degrees Celsius, the ecosystem's ability to recover between heat events diminishes, leading to a higher risk of catastrophic wildfires and systemic pressure on urban infrastructure not designed for such extremes.
