Nestled in the heart of the Morelos state, Jiutepec occupies a strategic position within Mexico's central highlands, approximately 70 kilometers south of Mexico City. Its geographical setting is defined by the transition from the higher altitudes of the Trans-Mexican Volcanic Belt to the more temperate valleys. Jiutepec is situated at an elevation of roughly 1,400 meters above sea level, contributing to its generally mild climate. The city is part of a broader urban corridor that stretches across the state, characterized by a mix of residential areas, burgeoning industrial zones, and significant agricultural activity, particularly in the surrounding rural peripheries where sugarcane and other crops are cultivated. This urban–rural gradient influences local air quality, as agricultural practices can contribute to particulate matter and gaseous emissions. The proximity to larger metropolitan areas like Cuernavaca and even the distant but influential air basin of Mexico City means Jiutepec is not immune to regional pollution transport. The terrain, featuring rolling hills and fertile plains, can influence wind patterns, sometimes trapping pollutants in localized valleys during specific meteorological conditions, while at other times offering pathways for dispersion. The absence of major nearby bodies of water means atmospheric moisture is primarily driven by regional weather systems rather than local evaporative sources.

Jiutepec experiences a distinct tropical savanna climate, marked by a pronounced wet and dry season, which significantly dictates its air quality patterns. The dry season, typically spanning from November to April, is characterized by lower humidity, increased solar radiation, and often, reduced rainfall. During these months, a buildup of pollutants can occur due to stagnant air masses and the increased frequency of temperature inversions, particularly in the early mornings and late evenings. This period, especially from March to May, often sees the highest pollution levels, exacerbated by dust from dry soils and increased vehicular emissions as people utilize their vehicles more frequently in fair weather. Conversely, the wet season, from May/June to October, brings substantial rainfall and stronger winds associated with the North American Monsoon. The rain acts as a natural cleansing agent, washing particulate matter from the atmosphere, while increased wind speeds aid in pollutant dispersion. This period generally offers cleaner air, making it more favorable for outdoor activities. Sensitive groups, such as the elderly, children, and individuals with respiratory or cardiovascular conditions, should exercise caution during the dry season's peak pollution months, limiting strenuous outdoor exertion and staying informed about local air quality advisories. The transition periods between seasons can also present variable air quality.
