Western Europe experienced record high temperatures and unusually low water levels throughout June and July [1, 2].
These climatic extremes signal an acceleration of heat stress in the region, threatening water security and infrastructure across several nations, including Germany [1, 2].
Data released Monday by the EU climate observation programme Copernicus and the EU climate services indicates that the average temperature in Western Europe for June and July reached 21.62 °C [1]. This figure represents a significant deviation from historical norms, a temperature anomaly of +2.79 °C relative to the 1991-2020 reference period [1].
Beyond recent benchmarks, the heat persists as a long-term trend. The temperature anomaly relative to the pre-industrial average was +1.39 °C [2]. This sustained increase in heat is driving the current environmental crisis, contributing to the reduced river flows observed across the region [1, 2].
The reports highlight a pattern of ongoing climate change that pushes temperatures well above established baselines [1, 2]. While specific city-level data was not detailed, the broader regional impact includes severe heat stress and critical drops in water levels in Western European waterways [1, 2].
Copernicus monitors these shifts to provide early warnings and data for climate adaptation. The current findings suggest that the intensity of summer heatwaves is increasing in both frequency and magnitude [1].

The divergence between current temperatures and the 1991-2020 baseline suggests that historical weather patterns are no longer reliable predictors for European summers. The simultaneous occurrence of record heat and low water levels creates a compounding crisis, where higher temperatures increase evaporation while reduced river flows hinder transport and cooling systems.
