Kotka's air quality reflects the Gulf of Finland coastal position in eastern Finland, with the Kotka-Hamina port complex's timber, paper, and container operations generating elevated PM2.5 alongside vehicle traffic on the E18 motorway. The Gulf of Finland sea breezes provide coastal ventilation, while the surrounding southeastern Finnish archipelago and the port operations represent the most distinctive local emission sources and the Baltic maritime climate generally maintains moderate conditions throughout most of the year.

Is air quality bad in Kotka right now?
On 9 August 2026, overall air quality in Kotka is fair. AQI is the main air quality indicator at 29.0/100. Pollution peaks around 6:00 PM (O3: 29.0/100).

When is air pollution at its worst in Kotka?
Reduced air quality in Kotka is most likely when local tree and grass allergens peaks, alongside periods of the Kotka-Hamina port complex's timber, paper, and container operations; cooler, breezier weather later in the year tends to bring things back down.
Are air quality levels in Kotka 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.
