Spain Braces for a Potential 'Super El Niño' Summer — Experts Give It a 61% Chance

What Is a 'Super El Niño'?

A normal El Niño happens when sea surface temperatures in the tropical Pacific warm by at least 0.5°C above average. A Super El Niño sees those temperatures spike by 2°C or more above normal — creating much stronger shifts in global wind patterns, jet streams and pressure systems.

These rare events have only happened a handful of times since 1950, but when they do, they can amplify heatwaves, storms and drought far more intensely than a regular El Niño.

61% Chance This Summer

Meteorologist Mar Gómez puts the current probability at 61%, saying it is "more likely to happen and could be much more intense." The shift from cooler La Niña conditions to something warmer is already underway, with forecasts showing a good chance of El Niño taking hold through the end of the year.

What It Could Mean for Spain

The link to Spain is not straightforward, but El Niño can influence southern Europe by encouraging warm air from North Africa to push north more often. This tends to mean:

• Longer or more frequent heatwaves — especially when layered on top of global warming, which already raises baseline temperatures
• South and centre of Spain facing the brunt of persistent high temperatures
• Northern areas getting some protection from Atlantic air, but still at higher risk than normal
• Potential for heavy rain in some spots and drought in others

Recent spring days with 30°C readings — even in the north — give a taste of what could lie ahead.

Stacking Heat on Heat

The main concern is how a Super El Niño might stack another layer of heat on top of what is already a warming trend. Spain has experienced increasingly hot summers in recent years, and a strong El Niño event could push 2026 into record-breaking territory.

What Should You Do?

Experts stress these are probabilities, not guarantees — spring forecasts can shift as summer approaches. But the ingredients are lining up for something significant. Practical steps:

• Stay aware of AEMET forecasts throughout summer
• Think ahead about how hotter temperatures affect daily life — hydration, outdoor activity, pets
• Be prepared for wildfire warnings, especially in the south and east
• Consider energy costs — air conditioning demand could push bills higher
