Beijing Climate

Humid continental climate with cold, dry winters (−8 to 2°C) and hot summers (28–35°C). The primary flight disruption risks are winter fog and smog (November–February, heavily air quality-dependent), summer thunderstorms (July–August), and spring sandstorms from the Gobi Desert (March–May) that can reduce visibility rapidly.

Fall (September–October) brings clear skies and minimal disruptions. The 2022 Winter Olympics improved Beijing's snowfall preparedness. Fog and smog remain serious delay causes through winter.
