Cherukunnu, nestled in the Malappuram district of Kerala, India, occupies a geographically significant position within the state's verdant landscape. Located at approximately 12.0041° N latitude and 75.3004° E longitude, the town sits at a relatively low elevation, contributing to a humid, tropical climate. The surrounding terrain is characterized by gently sloping hills and fertile plains, typical of Kerala's coastal region. This area is part of the Western Ghats foothills, influencing local weather patterns and drainage. Cherukunnu’s proximity to the Arabian Sea, roughly 20 kilometers to the west, plays a crucial role in moderating temperatures and influencing humidity levels. The town is surrounded by a mosaic of agricultural land, primarily dedicated to rice cultivation, coconut plantations, and spice farming – a common feature of Kerala’s rural economy. The urban–rural gradient around Cherukunnu is gradual; the town itself is relatively small, transitioning seamlessly into the surrounding agricultural areas. While Cherukunnu isn't directly adjacent to major industrial belts, it benefits from its connection to larger regional hubs like Calicut (Kozhikode), which introduces potential for transported pollutants. The prevailing winds, often influenced by the monsoon patterns, can carry pollutants from these distant sources. The dense vegetation surrounding the town generally acts as a natural filter, but localized agricultural practices, including burning of crop residue, can contribute to short-term air quality fluctuations. The town’s compact size and relatively low population density (16,111) generally mitigate urban-specific pollution sources like heavy traffic congestion, though increasing vehicle ownership is a growing concern.

Cherukunnu’s tropical climate dictates a distinct wet and dry season pattern, significantly impacting air quality. The southwest monsoon, typically spanning from June to September, brings torrential rainfall, effectively cleansing the atmosphere and dramatically reducing particulate matter. This period generally offers the best air quality, with frequent rain showers washing away pollutants and high humidity preventing dust accumulation. Conversely, the pre-monsoon months (March-May) often experience a build-up of pollutants. Hot, dry winds, coupled with stagnant air due to temperature inversions, trap emissions from agricultural burning and localized sources. This period is characterized by increased levels of suspended particles and potential respiratory irritation. The post-monsoon season (October-November) sees a gradual improvement in air quality as rainfall decreases, but lingering humidity can still trap pollutants. Fog, particularly in the mornings during this period, can also exacerbate the issue by reducing visibility and concentrating pollutants near ground level. December and January are generally milder, with relatively stable air quality. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during the pre-monsoon months, limiting outdoor activities during peak pollution hours. Agricultural workers should be particularly mindful of smoke exposure during this time. Maintaining indoor air quality through ventilation and air purifiers is advisable during periods of elevated pollution. The monsoon season provides a natural respite, but even then, localized agricultural practices can temporarily impact air quality.
