More Canadian wildfire smoke has enveloped the US midwest, mid-Atlantic, and north-east, affecting approximately 109 million people. Tens of millions of Americans are facing another day of smoky skies, irritated eyes, and poor air quality due to the spread of Canadian wildfire smoke across vast areas of the US.
The pungent wildfire smoke has blanketed cities such as Chicago and Detroit, where residents were warned to stay indoors and reduce activity levels on Friday after the air quality index reached a hazardous level of 361, according to the government website AirNow. The smoke drifted into Baltimore and Washington DC overnight, resulting in very unhealthy air quality with index values of 281 and 247, respectively, as of 6am eastern time. In New York City, where smoke has been present since Tuesday, the air quality stands at an unhealthy 184.
Philadelphia and Cleveland had readings considered very unhealthy at about 260. Other parts of Michigan, Minnesota, and Wisconsin also recorded readings in the hazardous range. The global air quality index showed pollution in five major North American cities at higher levels than Kinshasa or Nairobi in Africa. Nasa’s Fire Information for Reto the Northwest Territories
In Michigan, the state’s department of environment, Great Lakes, and energy recommended closing windows, minimizing the opening of doors, and using HVAC systems rated Merv-13 or higher. If people must be outdoors for short periods, an N95 or P100 respirator marked with NIOSH is recommended. Some cities in the north-east and New England are expected to get relief from smoky skies on Friday as stronger winds from Quebec blow the smoke out.
There has been a clear intensification in wildfire activity in Canada over the past few weeks, according to Mark Parrington, senior scientist at the Copernicus Atmosphere Monitoring Service. Smoke from major fires, particularly in Ontario, is already having severe air quality impacts across cities in the Great Lakes region and the north-eastern United States. Forecasts show the smoke continuing to move eastwards across the North Atlantic, potentially towards Europe, highlighting the scale of wildfire pollution and its ability to travel thousands of kilometers across borders and impact air quality in places far beyond the fires themselves.

However, an approaching storm system from the west, bringing severe thunderstorms, could interact with the smoke, creating worse conditions as rain drags smoky air from higher up in the atmosphere down to the ground. When the storm passes late on Saturday, air quality is likely to improve in time for a 3pm Sunday kick-off, forecasters say.
Canada’s largest fire, near Ontario’s remote Wabakimi provincial park, is reported to be spread across 787,802 acres. It is among 194 out-of-control and large fires that were burning as of Thursday. Parrington said smoke plumes from the large-scale wildfires in Canada’s Northwest Territories had reached the Arctic Ocean as well as across other parts of the country. Nearly 6 million acres are estimated to have burned, less than a quarter of the land consumed by blazes when Canadian wildfire smoke last blanketed the US in 2023. Fires in northern Minnesota have burned more than 63,000 acres.
In the west, wildfires in Oregon, Washington, and Idaho have also been reported. The wildfire situation across North America has worsened, with tens of thousands of lightning strikes across the Pacific Northwest igniting dozens of new wildfires across Oregon and Washington, according to forecaster Colin McCarthy.
