Struthers sits directly on the old Youngstown Sheet and Tube steel corridor along the Mahoning River, though the mills that once shaped local air quality here have been closed for decades. Tree cover around Mill Creek Park and along Yellow Creek helps trap a share of local particulates before they spread further.

Frequently Asked Questions
Is air quality bad in Struthers right now?
On 20 September 2026, overall air quality in Struthers is good. AQI is the main air quality indicator at 19.8/100. Pollution peaks around 1:00 PM (O3: 19.8/100).
Will air quality be worse tomorrow in Struthers?
On 21 September 2026, air quality conditions in Struthers will be worse than today, with AQI forecast at fair at 31.3/100. Pollution peaks around 5:00 PM (NO2: 31.3/100).
When is air pollution at its worst in Struthers?
In Struthers, particulate matter usually peaks in winter, driven by home heating and vehicle emissions trapped by cold, still conditions. Summer heat and sunlight typically push ozone to the top of the seasonal concerns here. The Mahoning River valley's terrain can still trap cold-season emissions from traffic and heating on the calmest days. Spring and fall, with milder temperatures and steadier wind, generally offer the cleanest air of the year.
Are air quality levels in Struthers based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
