Xingtai is a prefecture-level city situated in the southern part of Hebei Province, China, positioned within the vast North China Plain at coordinates 37.0717°N, 114.5048°E. This location places it approximately 400 kilometers southwest of Beijing and 120 kilometers north of the Yellow River, embedding it firmly within one of China's most densely populated and industrially intensive regions. The city's terrain is predominantly flat, with an average elevation of around 70 meters above sea level, characterized by alluvial plains formed by the ancient Yellow River and its tributaries, which historically deposited fertile soils but now contribute to particulate matter resuspension. Xingtai lies at the heart of the Hebei Industrial Belt, surrounded by agricultural zones that transition into urban sprawl, creating a stark urban–rural gradient where pollution sources from manufacturing, coal-fired power plants, and vehicular emissions converge with agricultural burning and dust from construction. Its proximity to the Taihang Mountains to the west provides some topographic shelter but also traps pollutants under stable atmospheric conditions, while the absence of significant bodies of water nearby—such as large lakes or seas—limits natural cleansing through precipitation and humidity, exacerbating air stagnation. This geographic setting, combined with its role as a transportation hub linking northern and central China, results in compounded air quality challenges, with pollutants accumulating due to limited dispersion in the basin-like plain, making it a hotspot for particulate matter and gaseous emissions in East Asia.

In Xingtai, air quality follows a distinct seasonal pattern shaped by the East Asian monsoon and local meteorological conditions. During winter (December to February), pollution peaks due to coal combustion for heating, coupled with frequent temperature inversions that trap pollutants near the surface, creating dense smog episodes; sensitive groups, such as children and the elderly, should avoid prolonged outdoor activities and use air purifiers indoors. Spring (March to May) sees moderate improvement as winds increase, dispersing some pollutants, but dust storms from the Gobi Desert can elevate particulate levels, making late spring more favourable for outdoor exertion. Summer (June to August) brings the highest air quality due to the East Asian summer monsoon, which introduces southeasterly winds and increased rainfall that scrub pollutants from the atmosphere, though high temperatures can occasionally lead to ozone formation; this season is optimal for outdoor recreation, with minimal health advisories. Autumn (September to November) marks a transition, with pollution gradually worsening as heating systems activate and atmospheric stability returns, leading to haze buildup; residents should monitor air quality forecasts and limit exposure during calm, foggy days. Throughout the year, wind patterns from the northwest and southeast play a crucial role, with stagnant conditions in winter and spring exacerbating pollution, while the monsoon in summer provides relief, guiding health recommendations to prioritize indoor activities during peak months and embrace outdoor opportunities in summer.
