Air Quality in Northwest Indiana Impacted by Wildfire Smoke

Northwest Indiana is currently experiencing the effects of Canadian wildfire smoke, leading to an Air Quality Action Day and the cancellation of events across the region. The Indiana Department of Environmental Management (IDEM) noted on Thursday that heavy wildfire smoke was moving into the state from the north, influenced by light winds and stagnant conditions. This has resulted in high fine particulate matter readings, reaching the ‘Very Unhealthy’ range for parts of Northwest, North Central, and Northeast Indiana.

By Thursday, the haze from the wildfires in Minnesota and Canada had enveloped Chicago. Smoke is expected to linger in northern Indiana on Friday, while central and east central Indiana may see unhealthy air quality levels for sensitive groups.

In areas of Northwest Indiana, fine particulate matter levels ranged from 201 to 300 on IDEM’s air quality scale of 500. Chicago recorded an air quality level of 395 out of 500 according to AirNow.

Several locations, including the Hobart Pool, closed on Thursday due to poor air quality. The Summer Market on the Lake was also canceled. Officials advised against prolonged or strenuous outdoor activities, recommending that individuals with heart or lung conditions, older adults, children, and teenagers limit outdoor exposure. Indoor activities were encouraged until air quality improves.

Indiana Dunes National Park officials used Instagram to alert visitors to monitor conditions on AirNow.gov and take necessary precautions, especially those with asthma or other sensitivities to air pollution.

Munster Parks and Recreation announced on Facebook that the summer camp would avoid the community pool due to air quality concerns. While Hammond’s Festival of the Lakes continued as planned, attendees were advised to stay hydrated and wear appropriate clothing in the heat.

AccuWeather reports over 800 wildfires burning across Canada. Smoke, particularly from southwestern Ontario, contributed significantly to air quality issues, prompting IDEM to declare previous Air Quality Action Days for Monday, Tuesday, and Wednesday in Northwest Indiana.

Air quality concerns also arose from high temperatures, sunny skies, and stagnant conditions throughout the region. On Wednesday, ozone levels were high due to very high temperatures and low humidity.

State climatologists and meteorologists suggest that high-pressure systems in the central U.S. often bring air from Canada, exacerbating wildfire smoke issues in the Great Lakes area, particularly during this time of year.
