Impact of El Niño on the 2026 World Cup

As Mexico and South Africa prepare to open the men’s soccer World Cup on June 11, 2026, anticipation is high for both on-pitch action and off-pitch weather events at Estadio Azteca, now referred to as Mexico City Stadium. The National Oceanic and Atmospheric Administration (NOAA) anticipates the emergence of El Niño during the May to July period, potentially influencing the climate during one of football’s biggest events held across the United States, Mexico, and Canada.

Understanding El Niño’s Influence

El Niño, characterized by unusually warm surface water in the equatorial Pacific and weaker easterly trade winds, typically recurs every two to seven years. It impacts weather patterns, particularly in the winter, rather than during the summer when the 2026 World Cup will occur. While El Niño affects temperature and precipitation, these impacts are weaker during the Northern Hemisphere summer.

NOAA uses the Relative Oceanic Niño Index to monitor El Niño, taking into account atmospheric conditions along with sea surface temperatures. The timing of such events determines a World Cup’s link to El Niño, which only truly impacts if it overlaps significantly with the tournament timeframe, as was the case during the 1998 World Cup in France.

Historical Context – France 1998

The 1998 World Cup stands out as it coincided with one of Earth’s strongest El Niño events. Beginning in May 1997 and persisting through 1998, this event was noted for major climate impacts, such as increased sea-surface temperatures and shifts in rainfall and atmospheric patterns. The Oceanic Niño Index showed high values at the time, leading to 1998 being one of the warmest years on record. Despite a fading El Niño by May 1998, its earlier, powerful presence left lasting effects.

Potential for El Niño in 2026

NOAA’s current predictions set the possibility of El Niño at 82% during May to July 2026, increasing to 96% for the end of that year. The latest data shows ENSO-neutral conditions recently, pointing to a modest Niño-3.4 reading of +0.4°C. NOAA emphasizes that strong El Niño requires significant summer coupling of ocean and atmosphere. This connection can influence certain climate aspects, like lowering Atlantic hurricane activity, but does not necessarily predict local weather conditions during the tournament.

The Reality of El Niño World Cups

In conclusion, France 1998 remains the only clear example of a World Cup significantly impacted by El Niño’s powerful climate characteristics. Although some tournaments like 1982, 2010, and 2014 occurred near El Niño phases, they lacked the distinct and powerful impact seen in 1998. Thus, the relationship between El Niño and World Cups, particularly those scheduled in summer months, remains minimal.
