The men’s soccer World Cup is set to kick off on June 11, 2026, at Estadio Azteca in Mexico City, known as “Mexico City Stadium” during the tournament. As excitement builds for this global event, climate experts predict the emergence of El Niño during the May to July window.
El Niño is one of Earth’s most influential climate patterns, impacting weather across the globe.
The 2026 World Cup, held across the United States, Mexico, and Canada, coincides with the potential onset of El Niño. Historically, only the France 1998 World Cup aligns with a significant El Niño event.
Understanding El Niño
El Niño is part of the El Niño—Southern Oscillation, a climate pattern characterized by warming ocean surface waters in the equatorial Pacific and weakened easterly trade winds. It occurs every two to seven years, lasting nine to 12 months, with its greatest effects during winter in the United States, altering temperature and precipitation patterns significantly.
While the World Cup usually avoids these peak impacts by happening in June and July, El Niño’s influence during summer is less pronounced, as noted by the Climate Prediction Center.
Historical Context and Measurement
The occurrence of El Niño is measured using the Oceanic Niño Index, with a reading of +0.5°C or more marking its presence. Besides historical comparisons, the Relative Oceanic Niño Index is used to evaluate its strength based on atmospheric conditions and persistence.
A tournament may coincide with an El Niño event, but whether it affects the matches depends on its timing and strength during the tournament window.
France 1998: An El Niño World Cup
France 1998 stands out as an event deeply influenced by El Niño, deemed powerful enough to impact climate globally. NASA described the 1997–98 El Niño as exceptionally strong, significantly altering sea surface temperatures and Pacific circulation.
The Oceanic Niño Index documented high values throughout early 1998, marking France’s triumph during a period of climate shifts.
Other tournaments, including 1982, 2010, and 2014, have connections to El Niño, but they do not meet all criteria for impact within the match window.
France won in 1998, defeating Brazil in standard Paris summer conditions.
The Potential for 2026
NOAA has identified El Niño Watch status as of May 14, 2026, with predictions of its emergence during May—July 2026. While prior conditions remained neutral, expectations for a strong El Niño remain cautious.
Though an El Niño overlap exists, its effects on the tournament’s weather could be minimal without ocean-atmosphere coupling.
Fans may experience heat, storms, or travel complications, although these would require local attribution rather than an El Niño link.
Conclusion: El Niño and the World Cup
The steady calendar of the men’s World Cup often mismatches with El Niño’s peak effects, maintaining the 1998 tournament as a unique instance of a true El Niño World Cup.
Predictions for 2026 involve careful climate monitoring, with the potential for correlation, but not causation. Ultimately, France’s experience remains unmatched in terms of documented global climate impacts during the event.
