The ongoing wildfires in Canada have led to significant air quality deterioration across large parts of the United States, causing Six Flags Great America and its adjacent water park, Hurricane Harbor Chicago, to close temporarily. The amusement park, located in Gurnee, Illinois, issued a notice confirming the closure on Friday, July 17, due to unsafe air conditions.
A spokesperson for the park indicated that they are actively monitoring air quality levels and expect to reopen the attractions by Saturday, July 18, contingent upon improvements in environmental conditions. The decision to close stems from advice provided by safety and weather experts as thick smoke from the wildfires has gradually spread southward.

As of the morning of July 17, Chicago recorded air quality levels classified as “hazardous” – the worst of any major city in the world. By later in the day, conditions had somewhat improved to the “unhealthy” category, as outlined by local news sources ABC 7 Chicago and NBC Chicago. However, an air quality alert remained in effect for the region, forecasted to last until Saturday night.
The source of this alarming air quality situation is primarily attributed to the hundreds of active wildfires in Canada. As of the recent reports, there were an astonishing 859 fires blazing across the country, with 113 classified as “out of control,” according to information released by the Canadian government.
This situation isn’t isolated to Illinois; regions across the Great Lakes, Northeast, and Mid-Atlantic have also been impacted, resulting in over 100 million US residents being subjected to unhealthy air quality. As smoke continues to drift southward, the health implications for those affected are becoming increasingly concerning.
Pulmonologist May-Lin Wilgus from UCLA weighed in on the potential health risks associated with inhaling wildfire smoke. Describing the situation to NPR, he likened exposure to high levels of airborne toxins to smoking multiple cigarettes. Notably, if the Air Quality Index (AQI) measures between 100 and 200, this could equate to the harmful effects of smoking a quarter to half a pack of cigarettes in a day.
Both healthy individuals and those with pre-existing health conditions face significant health risks when exposed to such hazardous air. Wilgus advised the public to remain indoors where possible, refrain from strenuous outdoor activities, and consider wearing N95 masks if venturing outside is unavoidable.
Six Flags Great America expressed gratitude for their guests’ understanding during this period and assured that safety remains their priority as they navigate these challenging circumstances. The park remains hopeful for a timely reopening, allowing families to enjoy the attractions once conditions permit.
In a broader context, the situation highlights the ongoing environmental challenges posed by climate change, including increased frequency and intensity of wildfires. As millions continue to be impacted by these events, the implications for public health and safety become ever more paramount, prompting discussions around preparedness and response to such natural disasters.
As the weekend approaches, visitors and locals alike remain attentive to air quality updates and the potential for reopening beloved entertainment venues disrupted by these environmental challenges. For now, all eyes are on the skies as communities respond to the ongoing crises unfolding due to wildfires to the north.
