Volunteers and staff dashed inside for cover as ponchos were handed out. The sky was the same thick, soupy grey it had been for days.New Jersey Governor Mikie Sherrill warned residents about the potential for damaging winds, tornadoes, flash flooding and large hailstones.FIFA said it was in close contact with local authorities as it continues to monitor the impacts from the wildfire smoke and the storms on the stadium conditions for the final.Have the weather and smoke disrupted preparations for Spain or Argentina?Spain’s last training session ahead of the final at a nearby Melanie Lane Training Ground was suspended because of storms and lightning in the area.The Spanish football federation (RFEF) said that was in accordance with US storm safety protocol.“The players are currently taking part in a warm-up session indoors,” RFEF added.FIFA said that there would not be another time slot for the team to train.Argentina had an outdoor training session at their scheduled time of 1:30pm (17:30 GMT), with players showing no concerns about air quality or the weather.Lionel Messi and the Argentina squad unaffected by the weather on the eve of the World Cup final, July 18, 2026. (AP Photo/Ashley Landis)Will the wildfire smoke affect the World Cup final?The haze will mostly clear from New Jersey just in time for the final, thanks to thunderstorms passing through the area, meteorologists say.“This storm front will largely move the smoke out of the northeast before the final between Spain and Argentina,” said Tyler Roys, a senior meteorologist at online weather service AccuWeather.“There could be some lingering smoke that would make things hazy, but very faint,” Roys said. “In terms of the thickest smoke, the smoke that has really been eye-popping and leads to poor air quality, that is not expected across New York City or much of the northeast.”Jeff Berardelli, chief meteorologist and climate specialist at WFLA-TV, echoed the forecast, saying the storm front would “sweep the atmosphere clean”, leaving only a thin smoke that World Cup spectators may still smell in the air.“It won’t be dangerous anymore,” Berardelli said. “It’s going to be dramatically better.”Temperatures are forecast to be around 27C (80F) with light breezes and low humidity for kick off.“You couldn’t have asked for much better weather for the World Cup,” Berardelli added.Both experts expect the heavier smoke on Sunday to be concentrated closer to the fires, hanging over parts of the Midwest and Great Lakes region.Berardelli said they are burning longer and faster because of climate change.
