Worst air pollution Fernhook Falls Campground - North Walpole, today and tomorrow

On 25 August 2026, overall air quality in Fernhook Falls Campground is good. AQI is the main air quality indicator at 15.5/100. Pollution peaks around 12:00 PM (O3: 15.5/100).

On 26 August 2026, air quality conditions in Fernhook Falls Campground will be similar to today, with AQI forecast at good at 16.3/100. Pollution peaks around 5:00 PM (O3: 16.3/100).

This area typically sees its worst air quality during the winter season, as rural heating sources add up under inversions that keep smoke from dispersing. As the weather warms and fire risk rises, smoke haze tends to overtake other concerns in this area, since summer heat and dry vegetation nearby are usually enough on their own to raise bushfire risk.

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.
