Manilva, nestled along the western Costa del Sol in Andalusia, Spain, occupies a unique geographic position that significantly influences its air quality. Situated at approximately 36.38°N, 5.25°W, the town lies on a gently sloping coastal plain, bordered by the Mediterranean Sea to the south and the Sierra Bermeja mountains to the north. This location creates a complex interplay of maritime and orographic influences. The surrounding landscape is characterized by a blend of cultivated terraces, primarily dedicated to olive groves and vineyards, and patches of Mediterranean scrubland, the *maquia*, which can contribute to particulate matter during dry periods. Manilva’s elevation ranges from sea level to around 200 meters, limiting the potential for significant vertical mixing of air pollutants. The proximity to the Strait of Gibraltar means the area is subject to prevailing westerly winds, which can transport pollutants from across the Atlantic, although these winds also generally provide a degree of natural ventilation. The urban–rural gradient is relatively smooth; Manilva is a small town integrated within a wider agricultural and tourism-driven landscape. While not directly adjacent to major industrial belts, it benefits from the broader Andalusian economy, and occasional transport-related emissions from the A-367 highway, connecting it to other coastal towns, can impact local air quality. The coastal location also means that sea breezes play a crucial role in dispersing pollutants, particularly during the warmer months, though fog events can trap them.

Manilva’s air quality exhibits a distinct seasonal pattern dictated by meteorological conditions. Summers (July-August) are typically characterized by high temperatures and prolonged periods of sunshine, often accompanied by thermal inversions. These inversions, where a layer of warm air sits above cooler air near the ground, suppress vertical mixing, trapping pollutants close to the surface. Agricultural activities, including pesticide application and soil tilling, can also contribute to localized emissions during this period. Spring (April-May) and Autumn (September-October) generally offer the most favourable air quality, with moderate temperatures and more frequent wind patterns that help disperse pollutants. However, autumn can see occasional episodes of Saharan dust intrusion, increasing particulate matter concentrations. Winters (November-March) are comparatively mild, but fog events are more common, particularly in the mornings, which can significantly reduce visibility and trap pollutants. The prevailing westerly winds are generally consistent throughout the year, but their strength and direction can vary, influencing the transport of pollutants. Sensitive groups, such as children, the elderly, and individuals with respiratory conditions, should be particularly cautious during summer months and when fog is present, limiting strenuous outdoor activity and monitoring for any respiratory discomfort. Agricultural workers should adhere to safety protocols regarding pesticide use and exposure. Maintaining awareness of regional air quality forecasts is advisable for all residents and visitors.
