Reykjavík's air quality is exceptional by global standards, with the North Atlantic Ocean's powerful subarctic westerlies and the famous Faxaflói Bay coastal position providing among the world's most powerful and consistent natural urban ventilation. Vehicle traffic on surrounding roads and the geothermal energy operations contribute local sources, while the extraordinary subarctic maritime exposure, the frequent Atlantic storm systems, and the absence of significant industry generally maintain Reykjavík among the world's cleanest major capital city environments throughout most of the year.

Frequently Asked Questions
Is air quality bad in Reykjavík right now?
On 9 August 2026, overall air quality in Reykjavík is good. AQI is the main air quality indicator at 19.4/100. Pollution peaks around 6:00 PM (O3: 19.4/100).
Will air quality be worse tomorrow in Reykjavík?
On 10 August 2026, air quality conditions in Reykjavík will be worse than today, with AQI forecast at fair at 21.1/100. Pollution peaks around 7:00 AM (PM2.5: 21.1/100).
When is air pollution at its worst in Reykjavík?
The biggest local contributor to pollution in Reykjavík is road traffic, particularly once dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Sea breezes typically keep conditions in check, except during still weather.
Are air quality levels in Reykjavík 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.
