Wānkāner, a town nestled in the Morbi district of Gujarat, India, occupies a geographically significant position within a region characterized by a gradual transition from the fertile plains of Gujarat to the more arid landscapes of the Kutch region. Located at approximately 22.6161° N, 70.9531° E, the town sits at a modest elevation, contributing to relatively stable atmospheric conditions, though not entirely mitigating pollution impacts. The surrounding landscape is predominantly agricultural, with extensive fields of cotton, groundnut, and pulses dominating the rural areas immediately bordering Wānkāner. This agricultural activity, while vital to the regional economy, introduces sources of particulate matter, particularly during harvest seasons when burning of crop residue is practiced. To the east, the Sukhadia Lake provides a localized moderating influence on temperature and humidity, though its impact on air quality is limited. Further afield, the industrial belt of Morbi, known for its ceramics and chemical industries, exerts a considerable influence. The urban–rural gradient around Wānkāner is relatively smooth, with smaller villages and agricultural holdings interspersed within the town's periphery. This proximity to both agricultural lands and industrial zones creates a complex interplay of pollution sources. The town's location within a relatively flat terrain can exacerbate the accumulation of pollutants, particularly during periods of low wind speed, as there are few natural barriers to impede their dispersal. The prevailing winds, generally from the west, carry pollutants from the industrial areas towards the eastern parts of the town and beyond.

Wānkāner's air quality experiences a distinct seasonal cycle heavily influenced by Gujarat's climate. The dry, cooler months of November through February present the most challenging period. Temperature inversions, common during this time, trap pollutants close to the ground, leading to increased concentrations. Agricultural burning, a widespread practice after the monsoon harvest, significantly contributes to particulate matter pollution during November and December. Fog, frequently occurring in January, further restricts atmospheric mixing and exacerbates the problem. March to May marks the pre-monsoon season, characterized by rising temperatures and increasingly stagnant air. Dust storms originating from the Thar Desert to the northwest can also impact air quality during this period. The onset of the monsoon season in June brings a welcome respite, as rainfall washes away pollutants and increased wind speeds disperse them. July and August typically see the best air quality throughout the year. However, the monsoon can also bring humidity, which can irritate respiratory conditions. September is a transitional month, with decreasing rainfall and a gradual return to drier conditions, often accompanied by a rise in pollutants as agricultural activities resume. Sensitive groups, including children, the elderly, and individuals with respiratory illnesses, should exercise caution during the dry winter months and the pre-monsoon season, limiting outdoor activity during peak pollution episodes. Staying indoors with air purifiers and wearing masks can offer some protection. The monsoon months offer the most favourable conditions for outdoor activities, though humidity should still be considered.
