Worst air pollution Walkway Over the Hudson - Poughkeepsie, today and tomorrow

On 30 August 2026, overall air quality in Walkway Over the Hudson is moderate. AQI is the main air quality indicator at 42.1/100. Pollution peaks around 1:00 AM (NO2: 42.1/100).

On 31 August 2026, air quality conditions in Walkway Over the Hudson will be better than today, with AQI forecast at fair at 31.7/100. Pollution peaks around 11:00 AM (O3: 31.7/100).

At Walkway Over the Hudson, air quality tends to follow Poughkeepsie's broader seasonal rhythm, as the cleanest conditions typically arrive with the more unsettled weather of spring and autumn; by contrast, summer heat waves, often worsened by haze drifting in from other regions, bring the year's worst air. Winter cold fronts tend to clear the air quickly, so extended pollution episodes are relatively uncommon.

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.
