Worst air pollution Havøysund, today and tomorrow

On 9 August 2026, overall air quality in Havøysund is good. AQI is the main air quality indicator at 15.1/100. Pollution peaks around 7:00 PM (O3: 15.1/100).

On 10 August 2026, air quality conditions in Havøysund will be similar to today, with AQI forecast at good at 16.1/100. Pollution peaks around 3:00 PM (O3: 16.1/100).

Havøysund typically sees the sharpest drop in air quality on the calmest, coldest days of winter, when still Arctic air can hold local smoke close to the ground for days at a time. The brief, intense summer and near-constant daylight otherwise keep the air clean most of the year. Most of the year, conditions in Havøysund stay comfortably within normal ranges.

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.
