Thessaloniki's air quality faces significant winter challenges, with residential wood burning in response to energy poverty combining with heavy traffic on the Thessaloniki ring road and port emissions from the busy harbour to elevate PM2.5 and NO₂. The Thermaikos Gulf provides ventilation on northwesterly winds, while the surrounding hills and the Axios valley can channel or concentrate emissions depending on wind direction.
