Scorching Hot Summer Ahead for Europe: MET Officially Warns of Heatwave 2025
Europe braces for a potentially sweltering season ahead, according to predictions by the Climate Institute. - Summer heat threatens Europe, potentially leading to extreme heatwaves and drought.
Get ready to crank up the AC, Europe! The Max Planck Institute for Meteorology (MPI-M) in Hamburg is predicting a sweltering summer for us this year. Their forecast aligns with predictions from the European Centre for Medium-Range Weather Forecasts, which also anticipates a scorching summer ahead.
The MPI-M team bases this prediction on ocean data. Historically, European heatwaves often precede a heat accumulation in the North Atlantic, which typically builds up about three years before an extreme heat event. Such extremely hot summers can be predicted up to three years in advance due to this connection. The cause of this heat accumulation is anomalies in oceanic heat transport, which also impact the atmosphere.
Researchers at the University of Hamburg have simulated European climate from 1962 to 2022 using a climate model developed at MPI-M. They analyzed simulations that showed the connection between North Atlantic heat accumulation and heat extremes. To test the quality of the predictions, they compared the simulations with observational data from 1964 to 2021, during which there were 18 unusually warm summers in Europe.
Heat accumulation in the sea suggests a heatwave summer
"The heat accumulation can also serve as a reliable indicator for future heatwave summers," said MPI-M researcher Lara Wallberg. According to the evaluation presented in the journal "Geophysical Research Letters", a heat accumulation is again evident at the end of the simulated period, suggesting an exceptionally hot summer for 2025.
Extremely warm summers are becoming more frequent in Europe, the research team explained. The frequency of heatwaves in Europe has doubled since pre-industrial times, and extremely warm summers that currently occur every ten years could occur almost every year by the end of the century.
Europe experienced one of the most dangerous heatwaves on record in 2003, leading to increased mortality rates, water shortages, and crop failures. The prediction of such extremes is crucial for human health and damage mitigation, the researchers emphasized.
World's oceans breaking heat records
The world's oceans, particularly the North Atlantic, have seen unprecedented heat records in recent years. For about a year, the average surface temperature in the North Atlantic was at its highest level ever recorded, often far exceeding the previous daily records. This is evidenced by data from the "Climate Reanalyzer" platform of the University of Maine in the United States.
The warming is far beyond natural fluctuations, climate experts have stressed. The primary cause is human activity: oceans absorb over 90% of the heat that remains in the atmosphere due to the increase in greenhouse gases.

- The Max Planck Institute for Meteorology in Hamburg predicts a sweltering summer for Europe in 2025, citing ocean data and a correlation between heat accumulation in the North Atlantic and extreme heat events.
- The MPI-M model calculation and the University of Hamburg study reveal that a heat accumulation in the North Atlantic, seen in recent years, can serve as a reliable indicator for future hot summers in Europe, such as the one anticipated for 2025. This increased frequency of hot summers is a concerning aspect of global climate change.
