Dense, suffocating smoke from Canadian wildfires is affecting major urban areas in the Midwest, Northeast, and mid-Atlantic, resulting in hazardous air quality for over 100 million individuals. In several regions, this air pollution is expected to persist until at least Saturday, as additional smoke drifts southward.

Here’s the current situation:
• Widespread impact: Air quality alerts are in effect for over 100 million residents across 18 states and Washington, D.C. Regions from northeast Minnesota to southeast Virginia are experiencing “very unhealthy” to “hazardous” air conditions.
• Expanding smoke coverage: On Friday, smoke continued to spread southward, with Washington, D.C., now facing critical air quality. The movement of smoke remains dynamic, as weather patterns will dictate which areas experience the most severe pollution daily.
• MLB game rescheduled: Due to the poor air quality in Cleveland, Friday’s game between the Cleveland Guardians and the Pittsburgh Pirates was postponed. It will be played on Saturday as part of a split doubleheader. Other events, including the RowFest National Championships in Michigan, were also canceled on Friday.
• Cancellations and closures: The smoke has negatively impacted outdoor summer activities in major U.S. cities. Events such as a baby parade in Flint, Michigan, a rock concert in Herndon, Virginia, and the America’s Mile marathon in Pittsburgh were all canceled as smoke lingered. Additionally, businesses have been adversely affected during this peak season, with amusement parks like Kennywood and Sandcastle Water Park in Pennsylvania closing due to the unhealthy air conditions.
• Anticipated relief: There is a possibility of multiple rounds of thunderstorms impacting areas from the lower Great Lakes to the Northeast on Saturday. While wildfire smoke may still contribute to hazy skies and unhealthy air, particularly early Saturday, a gradual thinning is expected from west to east. Rain, changing winds, and a cold front are anticipated to assist in clearing the smoke, although improvements in air quality may not be immediate everywhere.
• Most affected locations: As of Friday morning, Milwaukee, Chicago, and Detroit reported some of the worst air quality in the nation, with hazardous pollution levels extending into southern Ohio and West Virginia.
“Chicago is currently facing its most severe air quality on record,” stated the mayor’s office in a social media update on Thursday night. “Please remain indoors, and if you must go outside, wear a well-fitting N95 or KN95 mask for your protection.”
The Detroit Health Department is distributing free masks to residents on Friday and advising everyone to stay indoors. In Philadelphia, officials warned that “everyone is likely to experience health effects from exposure” to the smoke on Friday, as stated in a media statement.
In Washington, D.C., DC Health is providing masks to outdoor government workers, as reported to USdaily on Friday. Furthermore, outdoor government activities have been canceled, and outdoor pools and splash parks have been closed, according to the department.
Smoke disrupts lives across the US
Residents from Minnesota to Washington, D.C., shared with USdaily how the toxic air has disrupted various aspects of their lives, impacting their health, leisure, businesses, and family activities.
For many, the current shutdowns and mask recommendations evoke memories of the COVID-19 pandemic from about six years ago.
Erin Cotton, a mother from D.C., recounted to USdaily that she initially didn’t notice the smoke until her eyes began to burn and her young children complained of itchiness. “That’s when I recalled how I felt during the Palisades Fire,” said Cotton, who experienced the devastating fire in California last year.
On Friday, the activities at her daughter’s summer camp were disrupted, and cotton found herself spending twice as long in traffic as many opted to drive rather than walk around D.C.
“The kids came dressed for swimming but couldn’t go outside due to the poor air quality and smoke,” she mentioned. “All the children ended up upset.”
Another D.C. resident, Abigail Nguyen, was looking forward to enjoying the warm summer weather outdoors, but the smoke made her hesitant to continue her usual runs to the National Mall and walks with her dog.
“I can’t see three blocks ahead. Everything appears so hazy. My eyes were even stinging a bit,” she reported. “It feels like the air is more difficult to breathe due to the smoke. This is unlike anything I’ve ever encountered.”
Nguyen had planned to watch the World Cup at the National Mall, but now she intends to stay in and watch it with her roommates.
“I can’t fully enjoy the excitement and energy of the crowd, which is disheartening, because we should be celebrating this summer event instead of being stuck indoors.”
Coty Jen, a California native now residing in Pennsylvania, expressed that she has “experienced far more wildfires than she would like.”
“I keep my air filter running, and I’m still wearing an N95 mask while in my office,” shared Jen, who teaches chemical engineering at Carnegie Mellon University. “Smoke seeps in through window seams and doors. It envelops everything, causing my lungs to hurt and triggering headaches.”
Communities that are particularly vulnerable, such as those with pre-existing health conditions, the unhoused, or individuals who work outdoors, are facing greater challenges due to the hazardous air quality.
Jerrel Gilliam, the executive director of Pittsburgh’s Light of Life Rescue Mission, noted that community workers are increasing their outreach to unhoused individuals and including masks in the hygiene kits they distribute.
“Living without shelter becomes even more perilous in such weather because of dehydration. Individuals are perspiring and unable to rehydrate, putting them at risk,” Gilliam explained.
In Ohio, Dr. Megan Conroy anticipates assisting patients with asthma through the weekend and into the following week.
“My patients are reporting that they are experiencing symptoms, needing to use their rescue medications, and being very mindful of their activities,” the pulmonologist stated.
While some businesses that depend on summer foot traffic have had to close temporarily, others are determined to carry on with their plans.
The Northern Lakes Arts Association in Ely, Minnesota, is proceeding with its performance of “Jesus Christ Superstar” on Friday evening, even as wildfires rage nearby.
“We want to create a space for community gathering and shared experiences, providing them with a break from the smoke and fire, and alleviating the constant anxiety of what tomorrow may bring,” Ian Francis Lah, the executive artistic director, explained to USdaily.
Track the smoke
This summer, smoke has already posed challenges in parts of the West, Plains, and Midwest as wildfires have consumed over 3.6 million acres, primarily in the western regions. However, the thicker smoke currently affecting these areas originates from wildfires situated to the north.
In Canada, approximately 3,500 fires have scorched more than 6 million acres this summer, with several blazes igniting in Ontario recently, contributing to the smoke drifting south, similar to extreme conditions experienced in 2023.
Although the wildfire activity in Canada this year is not as intense as the record-breaking season of 2023, the combination of Ontario fires and a heat dome over the central U.S. is creating smoky conditions for millions.
Pollution from fossil fuels, which contributes to global warming, is increasing the likelihood of extended smoke seasons, indicating that extreme wildfire seasons like the devastating 2023 season in Canada may become more common.
Wildfire smoke contains harmful, tiny particles known as PM2.5 that can penetrate deeply into the lungs or enter the bloodstream when inhaled. These minuscule particles can result in respiratory issues such as bronchitis and can trigger inflammation that exacerbates conditions like diabetes and heart disease.
Individuals with lung or heart diseases, as well as children and older adults, are particularly susceptible to health issues related to smoke exposure. The National Weather Service recommends limiting outdoor activities and keeping windows closed at night to avoid smoke inhalation.
Smoke seasons are getting worse
In the U.S., the duration of unhealthy wildfire smoke outbreaks is increasing, as fire seasons in the West have lengthened and intensified.
Climate change has been identified as the primary cause of the surge in surface wildfire smoke. This smoke has negatively impacted air quality improvements seen over the past decades in various regions of the U.S., especially the West.
Canada’s unprecedented smoke event was so extensive that a study last year estimated that over 350 million individuals were exposed to daily air pollution from wildfire smoke.
Pollution from climate change resulted in around 15,000 additional deaths in the U.S. due to wildfire particulate matter between 2006 and 2020 compared to what would have occurred in a cooler climate, according to a study published last year.
