Kōrōth, a small town in Kerala, India, rests at coordinates 11.5833°N, 75.7667°E, nestled within the coastal plains of the Malabar region. With a population of approximately 16,969, Kōrōth’s geography is defined by its relatively low elevation, typical of Kerala’s western coastal strip. The terrain is largely flat, transitioning into the foothills of the Western Ghats further inland. This proximity to the Arabian Sea exerts a significant influence on the local climate and, consequently, air quality. Kōrōth isn’t a major industrial hub, but is surrounded by agricultural land – primarily rice paddies and coconut plantations – and smaller-scale brick kilns and rubber processing units. The urban-rural gradient is quite sharp; the town itself is compact, quickly giving way to dense vegetation and rural landscapes. This limits widespread dispersion of pollutants, potentially leading to localised air quality issues. The coastal location means sea breezes can offer some relief, but also contribute to humidity and salt spray. The lack of significant topographical features to trap or channel air masses means pollution events are often dependent on local emission sources and meteorological conditions. Understanding this interplay is crucial for assessing and mitigating air quality challenges in Kōrōth.

Kōrōth experiences a tropical climate, dominated by wet and dry seasons rather than traditional four seasons. Air quality generally improves during the Southwest Monsoon (June-September) as heavy rainfall effectively washes particulate matter from the atmosphere. However, increased humidity can also foster mould growth, impacting respiratory health. The post-monsoon season (October-November) sees a gradual increase in pollution as agricultural burning becomes common, preparing fields for the next crop. This contributes significantly to PM2.5 levels. The dry season (December-February) is typically the period of poorest air quality. Lower wind speeds and temperature inversions trap pollutants near the ground, exacerbated by vehicle emissions and localised industrial activity. January and February are months to be particularly cautious about outdoor exertion. The pre-monsoon season (March-May) brings rising temperatures and dust, further degrading air quality. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during these periods and consider using air purifiers indoors. Monitoring local weather patterns and agricultural practices is key to anticipating pollution spikes.
