Riga's air quality faces significant winter challenges, with residential wood and coal burning generating elevated PM2.5 alongside vehicle traffic on the ring road and the heavy transit corridor connecting the Baltic port. The Gulf of Riga and prevailing Baltic westerlies provide good ventilation on most days, while cold anticyclonic conditions in winter allow domestic heating emissions to accumulate across the flat Latvian capital.
