El Niño is a natural climate pattern that occurs when sea surface temperatures in the central and eastern Pacific Ocean become unusually warm. Although it develops thousands of miles away from Europe, it can influence weather patterns across the globe by altering atmospheric circulation. In recent years, scientists and media reports have discussed the possibility that the effects of El Niño could increasingly be felt in Europe, particularly as climate change intensifies extreme weather events.
People believe El Niño may have a stronger impact on Europe because climate change is making the atmosphere warmer and capable of holding more moisture. This can amplify the weather disruptions associated with El Niño. While El Niño does not directly “arrive” in Europe, its influence can spread through changes in jet streams and pressure systems, affecting temperatures, rainfall, storms, and drought conditions across the continent.
During an El Niño event, Europe often experiences different weather effects depending on the region and season. Northern Europe may see wetter and stormier winters, while parts of Southern Europe can experience warmer and drier conditions. However, these impacts are less predictable than in regions such as South America, Australia, or North America, where El Niño‘s effects are more direct and consistent.
The most recent major El Niño developed during 2023 and continued into 2024. Globally, it contributed to record-breaking temperatures, extreme heatwaves, severe droughts, and intense rainfall events. Europe experienced some of its warmest temperatures on record during this period, although climate scientists stress that these records were driven by a combination of El Niño and long-term human-caused climate change.
One of the strongest El Niño events in modern history occurred in 2015-2016. That event contributed to the then-highest global temperatures ever recorded. Around the world it caused droughts, floods, coral bleaching, crop failures, and significant economic losses. Europe experienced unusually warm conditions, with several countries recording exceptionally mild winters. The event demonstrated how a natural climate cycle can combine with global warming to produce more severe impacts.
Scientists are monitoring future El Niño developments closely because rising global temperatures may increase the severity of weather extremes linked to these events. While El Niño itself is a naturally occurring phenomenon, climate change is altering the background conditions in which it occurs. As a result, future El Niño events could bring even greater risks of heatwaves, flooding, drought, and other extreme weather across Europe and the rest of the world. Understanding these interactions is becoming increasingly important for governments, businesses, and communities preparing for a changing climate.
