Eastern Europe, 3 to 7 December 2025

For 5 days, from 3 to 7 December 2025, 64 cities in Poland, Germany, Slovakia and 3 more countries had PM2.5 at least twice their usual for the time of year. The worst reading was Żywiec, Silesia, Poland: 158.0 µg/m³ on 5 December, about 5.9× its usual 26.9. Ended 7 December.

Few fires were detected near these cities on those days. Spreads like this usually come from still weather trapping smoke from heating, traffic and industry, or from dust.
