Montecristi, nestled in the coastal province of Manabí, Ecuador, presents a unique geographic setting influencing its air quality. Situated at approximately -1.0500 latitude and -80.6667 longitude, the city lies close to the Pacific Ocean, experiencing a humid subtropical climate. The terrain is relatively flat, transitioning from coastal plains inland towards the foothills of the Andes, though Montecristi itself remains at low elevation. This proximity to the ocean introduces significant moisture and salt spray into the air, impacting particulate matter composition. The city’s urban character is a blend of traditional fishing communities and growing commercial activity, spurred by its port status. Surrounding Montecristi are extensive agricultural lands, primarily dedicated to banana, cacao, and palm oil cultivation. These agricultural zones contribute to potential air pollution through the use of pesticides and fertilizers, as well as biomass burning for land clearing. The urban-rural gradient is relatively sharp, with agricultural areas immediately bordering the city limits. The port itself is a key economic driver, but also a potential source of emissions from ship traffic and cargo handling. Prevailing winds generally blow from the ocean, influencing the dispersion of pollutants, but can also trap them during periods of calm.

Montecristi’s air quality follows a distinct wet and dry season pattern. The dry season, typically from June to November, sees a concentration of pollutants due to reduced rainfall and increased dust from agricultural activities and unpaved roads. Lower humidity during these months also means particles remain airborne for longer. August and September are often the months with the poorest air quality. Conversely, the wet season, from December to May, brings relief through rainfall that washes away pollutants and suppresses dust. However, increased humidity can also promote the formation of mold and mildew, impacting indoor air quality. February and March generally offer the clearest air. Temperature inversions, common during the calmer nights of the dry season, can trap pollutants near ground level, exacerbating conditions. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during the dry season, particularly in the late afternoons. The strong Pacific winds can provide some dispersion, but localized pollution from the port and agricultural areas can still be significant. Monitoring local conditions and adjusting activity levels accordingly is crucial.
