Alquízar, nestled in the Artemisa province of Cuba, occupies a geographically significant position within the western part of the island. Located at coordinates 22.8067, -82.5828, the city sits on relatively flat terrain, characteristic of the western Cuban plains. This area is part of a broader agricultural belt, heavily focused on sugarcane and citrus cultivation, which significantly influences the local air quality. The elevation is low, averaging around 50 meters above sea level, contributing to limited natural dispersion of pollutants. Alquízar is approximately 25 kilometers southwest of Havana, placing it within the sphere of influence of the capital’s industrial activity and traffic emissions, though buffered by distance. The proximity to the coastline, specifically the Gulf of Mexico, introduces a maritime influence, with sea breezes playing a role in pollutant transport. The urban-rural gradient is pronounced; Alquízar itself is a relatively small city, surrounded by extensive agricultural lands. This creates a complex interplay where agricultural practices – including burning of sugarcane fields post-harvest – can contribute to localized air pollution episodes, alongside emissions from smaller-scale industries and domestic sources. The surrounding landscape is predominantly flat, with scattered hills, limiting the effectiveness of topographical features in dispersing airborne particles.

Alquízar experiences a tropical climate, defined by a distinct wet and dry season rather than traditional four seasons. Air quality generally improves during the wet season (May to October) due to increased rainfall which effectively washes particulate matter from the atmosphere. However, high humidity can also trap pollutants closer to the ground. The driest months, November to April, typically see a decline in air quality. This is exacerbated by increased agricultural activity, particularly sugarcane harvesting and associated burning, releasing significant amounts of smoke and particulate matter. January and February are often the clearest months in terms of visibility, but also coincide with periods of stable atmospheric conditions, potentially leading to pollutant build-up. Wind patterns, predominantly from the east, play a crucial role in transporting pollutants from Havana towards Alquízar, particularly during the dry season. Temperature inversions, common during cooler nights, can trap pollutants near the surface. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during the dry season, especially when agricultural burning is prevalent. Monitoring local weather reports and avoiding peak burning times is advisable. The wet season offers better conditions for outdoor activities, but awareness of humidity-related respiratory issues is still important.
