Limassol, Cyprus's second-largest city, occupies a strategic coastal position on the southern shore of the Mediterranean island, nestled between the Troodos Mountains to the north and the Akrotiri Peninsula to the west. This urban centre, part of the Limassol District in West Asia, features a varied terrain that significantly influences its air quality dynamics. The city itself lies on relatively flat coastal plains, with elevations generally below 50 metres, facilitating urban sprawl and traffic congestion that exacerbate pollution from vehicle exhaust and construction dust. Its proximity to the Mediterranean Sea moderates temperatures but also exposes it to maritime influences, including port and shipping emissions from one of the busiest harbours in the Eastern Mediterranean. The surrounding landscape includes agricultural zones to the east and west, where occasional dust from farming activities can mix with urban pollutants. The Troodos Mountains create a natural barrier to the north, which can trap pollutants during periods of low wind, particularly in the cooler months. This urban–rural gradient sees pollution concentrated in the city centre, with some dispersion towards suburban areas. Saharan dust events, common in the region, periodically sweep across from Africa, adding particulate matter to the local airshed. The city's geography, combining coastal industrial activity, dense urban development, and regional dust transport, creates a complex air quality profile that requires careful monitoring.

In Limassol, air quality follows a distinct seasonal pattern shaped by its humid subtropical climate and local emissions. During winter, from November to January, pollution peaks due to a combination of factors: increased vehicle use and tourism traffic during the holiday season, coupled with meteorological conditions such as temperature inversions that trap pollutants near the ground. Cold, stagnant air and occasional fog exacerbate this, making these months the least favourable for outdoor activities, especially for sensitive groups like children, the elderly, and those with respiratory conditions. Spring brings some relief as temperatures rise and winds pick up, dispersing pollutants, though Saharan dust events can still occur, particularly in March and April. Summer sees high tourist influx and construction activity, but sea breezes and stronger winds help mitigate pollution levels, making it a better time for outdoor pursuits, though midday heat can pose other health risks. Autumn transitions back to poorer conditions as winds calm and emissions from port operations and early winter traffic build up. Sensitive individuals should monitor air quality reports, avoid strenuous outdoor exercise during peak pollution months, and consider using air purifiers indoors. Overall, late spring to early autumn offers the most favourable air quality for residents and visitors alike.
