Šiauliai's air quality reflects the flat Lithuanian northern highland position, with vehicle traffic on the Via Baltica A1 motorway and surrounding manufacturing and agricultural operations contributing local sources. Baltic westerlies generally provide reasonable ventilation on most days, while winter residential wood and heating oil burning generates seasonal PM2.5 elevation and the flat terrain allows reasonable dispersal, generally maintaining Šiauliai among Lithuania's more moderate urban environments.
