Worst air pollution Heckmondwike, today and tomorrow

On 9 August 2026, overall air quality in Heckmondwike is fair. AQI is the main air quality indicator at 33.9/100. Pollution peaks around 3:00 PM (O3: 33.9/100).

On 10 August 2026, air quality conditions in Heckmondwike will be similar to today, with AQI forecast at fair at 21.4/100. Pollution peaks around 3:00 PM (O3: 21.4/100).

Spring and autumn are typically the easiest months, air-quality-wise, for most residents. Heckmondwike doesn't have one fixed air quality level — it swings between two extremes each year. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the M9 closer to ground level. Come summer, it's ozone rather than particulates that's the bigger concern, especially on still, sunny days.

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.
