All to know about Canadian wildfire smoke, air quality and World Cup final

Canadian wildfires ignited earlier in the week have sent smoke across the northeastern United States, creating visibility challenges and air quality concerns in the lead-up to a major sporting event. The haze has been particularly pronounced in New York and New Jersey, with New York experiencing the world's worst air quality at one point on Friday. Warnings about unhealthy air conditions remained in effect across the US east coast through Saturday, though forecasts indicated improvement was imminent.

Weather disruptions accompanied the smoke, with a thunderstorm passing through the stadium area on Saturday afternoon, bringing heavy rain and thunder. Authorities directed spectators and staff to seek shelter, and New Jersey's governor issued warnings about potential damaging winds, tornadoes, flash flooding, and large hail. One team's training session was suspended due to storm and lightning safety protocols, while the other proceeded with an indoor warm-up instead.

Meteorologists expect the approaching storm front to clear most of the smoke from New Jersey before the match begins, improving air quality from unhealthy to moderate levels. Forecasts suggest the general public will face little to no health risk during the event, though conditions may remain moderate for sensitive groups. FIFA stated it was monitoring conditions closely in coordination with local authorities to assess any ongoing impacts on stadium operations.
