Bisceglie, a coastal city in the Puglia region of southeastern Italy, presents a unique geographic context influencing its air quality. Situated on the Adriatic Sea at coordinates 41.2409° N, 16.5021° E, the city occupies a relatively flat terrain, typical of the Tavoliere delle Puglie plain, though gently rising inland. This plain, historically an agricultural heartland, now sees a mix of intensive farming and light industrial activity. The immediate surrounding landscape is dominated by olive groves, vineyards, and fields, transitioning to more rugged terrain further inland. The Adriatic Sea exerts a significant moderating influence on Bisceglie’s climate, providing sea breezes that can both disperse and, under certain conditions, trap pollutants. The urban-rural gradient is relatively sharp, with agricultural land bordering the city limits. While Bisceglie isn’t a major industrial hub like some northern Italian cities, the presence of smaller-scale manufacturing, particularly related to food processing and building materials, contributes to localised emissions. The port, though modest, also generates some particulate matter from shipping activity. The prevailing winds are generally from the north-east, carrying pollutants from the Balkan Peninsula on occasion, and the city’s position makes it susceptible to Saharan dust events. This combination of factors creates a complex air quality profile.

Bisceglie’s air quality follows a distinct seasonal pattern. Summer months (June-August) typically experience the best air quality, driven by consistent sea breezes that effectively disperse pollutants. However, high temperatures can promote ground-level ozone formation, particularly on calm, sunny days. Autumn (September-November) sees a gradual deterioration as agricultural burning increases following the harvest, releasing significant particulate matter. Temperature inversions, common during this period, can trap pollutants close to the ground, exacerbating the issue. Winter (December-February) is often the most challenging period, with reduced wind speeds and increased reliance on domestic heating, primarily wood and fossil fuels, leading to higher concentrations of particulate matter and nitrogen oxides. Fog, a frequent occurrence, further compounds the problem by limiting dispersion. Spring (March-May) is a transitional phase, with fluctuating conditions. March can still experience winter-like pollution episodes, while May generally sees improving air quality. Sensitive individuals – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during autumn and winter months. Monitoring pollen levels is also crucial in spring, as these can exacerbate respiratory issues. Avoiding peak traffic hours and staying indoors on days with poor visibility are recommended precautions.
