Csongrád, nestled in the southern plains of Hungary within the Csongrád-Csanád county, occupies a geographically significant position within the Carpathian Basin. Its coordinates (46.7111, 20.1403) place it on relatively flat terrain, characteristic of the Great Hungarian Plain, with an average elevation of around 120 meters above sea level. The city’s location is heavily influenced by the proximity of the River Tisza, a major waterway that historically shaped settlement patterns and continues to impact local hydrology. Surrounding Csongrád is a predominantly agricultural landscape, dominated by arable fields used for crop cultivation, particularly cereals and sunflowers. This extensive agricultural activity contributes to seasonal dust and pollen dispersal, impacting air quality. To the east, the landscape gradually transitions into more wetland areas, reflecting the region's susceptibility to flooding. The urban–rural gradient around Csongrád is relatively gentle; smaller villages and agricultural holdings are interspersed throughout the surrounding countryside, creating a diffuse pattern of settlement. While Csongrád itself is a relatively small town, it serves as a regional hub for the surrounding agricultural communities. There are no major industrial belts immediately adjacent to Csongrád, however, larger industrial zones are present further north in the county, and transportation corridors carrying goods to and from these areas can influence local air quality through vehicle emissions. The flat topography and prevailing wind patterns can lead to the stagnation of pollutants, particularly during periods of calm weather, exacerbating local air quality challenges.

Csongrád’s air quality experiences a distinct seasonal cycle driven by meteorological factors and agricultural practices. Spring (March-May) often sees elevated pollen levels from the surrounding fields, triggering respiratory sensitivities in susceptible individuals. Dust storms, common during this period due to dry soil conditions and wind, can also degrade air quality. Summer (June-August) typically brings relatively cleaner air, aided by convective mixing – rising warm air that disperses pollutants. However, heatwaves can lead to temperature inversions, trapping pollutants near the ground, especially during stagnant weather. Autumn (September-November) presents a mixed picture. Agricultural activities, including harvesting and field preparation, release particulate matter into the air. Cooler temperatures and calmer winds can contribute to pollutant accumulation. Winter (December-February) is often the most challenging period. Cold, stable air masses frequently lead to temperature inversions, trapping pollutants and creating conditions conducive to fog, which further concentrates airborne particles. The use of domestic heating, often reliant on solid fuels, also contributes to increased particulate matter. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should limit outdoor exertion during periods of fog or temperature inversions, particularly in the winter months. Spring and autumn require awareness of pollen and dust levels, respectively. Generally, the months of June and July offer the most favourable conditions for outdoor activities, although vigilance regarding heatwaves remains important.
