Don Benito, nestled in the heart of Extremadura, Spain, occupies a geographically significant position within the Guadiana River Valley. Its coordinates (38.9545, -5.8617) place it on a relatively flat plain, averaging around 280 meters above sea level, characteristic of the wider Extremaduran landscape. The city’s urban fabric is defined by a traditional grid pattern, reflecting its historical development as a market town, surrounded by a gradually expanding residential area. The surrounding landscape is predominantly agricultural, with extensive olive groves, cereal fields, and vineyards dominating the vista. This proximity to intensive agriculture contributes to potential particulate matter emissions, particularly during harvest seasons. To the north, the terrain gently rises towards the Sierra de los Neveros, a range that can influence local wind patterns and, occasionally, trap pollutants. The Guadiana River, though not directly adjacent to the city center, plays a crucial role in the regional hydrology and influences microclimates. Don Benito’s location within the broader Extremaduran Meseta, a high-altitude plateau, means it experiences continental climate conditions, impacting air circulation. The urban–rural gradient is relatively smooth, with agricultural land seamlessly blending into the city’s periphery. While not situated near major industrial belts, the region supports livestock farming and some food processing industries, which can contribute to localized air pollution. The relatively low elevation and flat terrain, combined with the surrounding agricultural activity, create conditions where stagnant air masses can form, potentially exacerbating air quality issues.

Don Benito’s air quality follows a distinct seasonal pattern dictated by its continental climate. Summers (July-August) are typically hot and dry, characterized by prolonged periods of sunshine and minimal rainfall. This often leads to temperature inversions, where a layer of warm air traps cooler air near the ground, preventing pollutants from dispersing. Agricultural activities, including harvesting and burning of crop residues (though increasingly regulated), can also contribute to particulate matter during these months. Spring (April-May) and Autumn (September-October) generally offer the most favourable air quality, with moderate temperatures and more frequent rainfall, which naturally cleanses the atmosphere. However, autumn can still see localized pollution from agricultural practices. Winters (November-March) are colder, with occasional fog, particularly in the mornings. Fog can trap pollutants close to the ground, leading to periods of reduced visibility and elevated concentrations of certain pollutants. The prevailing winds, generally from the west, play a crucial role in dispersing pollutants, but their strength and direction can vary significantly. Sensitive groups, such as children, the elderly, and individuals with respiratory conditions, should be particularly cautious during the hot, dry summer months and on days with dense fog. Limiting strenuous outdoor activity during these periods and monitoring local air quality reports are advisable. The agricultural cycle significantly influences air quality, with increased emissions during planting and harvesting seasons. Maintaining awareness of weather patterns and agricultural practices is key to managing potential health risks.
