Worst air pollution Nacka Nature Reserve - Stockholm, today and tomorrow

On 30 August 2026, overall air quality in Nacka Nature Reserve is fair. AQI is the main air quality indicator at 29.1/100. Pollution peaks around 2:00 PM (O3: 29.1/100).

On 31 August 2026, air quality conditions in Nacka Nature Reserve will be similar to today, with AQI forecast at fair at 26.3/100. Pollution peaks around 5:00 PM (O3: 26.3/100).

When is air quality typically worst in Nacka Nature Reserve? Winter brings the greatest risk of short-lived pollution episodes, usually tied to wood-burning combined with a lack of wind. Spring usually marks a turning point, with more active weather systems reducing how often pollutants can accumulate. Summer generally brings the year's best air quality, thanks to longer days, more ventilation, and less need for heating. Autumn sees a gradual decline from summer's good conditions, as cooler weather brings back wood-smoke and less consistent wind. This pattern is fairly typical for central Sweden, where all four seasons are clearly distinct.

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.

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.
