Ince-in-Makerfield, nestled within the Metropolitan Borough of Wigan in Greater Manchester, occupies a geographically significant position in the North West of England. The town sits on relatively flat terrain, characteristic of the Lancashire Plain, at an elevation of approximately 55 metres above sea level. Historically, its location was dictated by proximity to the Sankey Canal and the River Mersey, vital transport arteries during the Industrial Revolution. This access facilitated the growth of heavy industry, particularly coal mining and chemical works, which profoundly shaped the area’s landscape and, consequently, its air quality. Today, the surrounding landscape is a mosaic of post-industrial land, reclaimed brownfield sites, and pockets of agricultural land. The urban-rural gradient is relatively sharp; moving east and west quickly transitions into more open countryside. The M6 motorway, a major transport corridor, runs close by, contributing to localised emissions. The prevailing winds, typically southwesterly, can carry pollutants from larger industrial centres like Liverpool and Manchester, impacting Ince’s air quality. The town’s compact urban form, combined with the flat topography, can also contribute to localised pollutant build-up, particularly during calm weather conditions. Understanding this interplay of factors is crucial for addressing air quality concerns.

Ince-in-Makerfield experiences a temperate maritime climate, with distinct seasonal variations impacting air quality. Winter (December-February) often sees poorer air quality due to increased reliance on domestic heating, particularly solid fuels, and temperature inversions trapping pollutants near ground level. Calm, damp conditions exacerbate particulate matter concentrations. Spring (March-May) brings a gradual improvement as temperatures rise and heating demand decreases, though agricultural activities can contribute to ammonia emissions. Summer (June-August) generally offers the best air quality, with prevailing winds dispersing pollutants and higher temperatures promoting atmospheric mixing. However, occasional heatwaves can lead to increased ozone formation. Autumn (September-November) sees a deterioration as heating use increases again, and damp conditions return, fostering pollutant build-up. November is often a particularly challenging month. Sensitive individuals – those with respiratory conditions, the elderly, and young children – should be particularly cautious during winter and autumn. Monitoring wind direction is key; periods of easterly winds can bring pollutants from industrial areas further east. Avoiding strenuous outdoor activity on still, cold days is advisable, and keeping windows closed during peak pollution episodes can help protect indoor air quality.
