New York Climate

Humid continental climate with hot summers and cold winters. LGA is one of the most disruption-prone major US airports. A combination of weather (nor'easters, summer thunderstorms, winter ice) and congested airspace drives delays year-round. Summer (June–August) afternoon thunderstorms cause frequent ground delays and can back up the eastern seaboard for hours.

Winter (December–February) brings snow and freezing rain events, with −5–4°C averages. Nor'easters typically cause 1–2 significant cancellation events per season. Spring and autumn are the most operationally stable periods. Connections through LGA require buffer time to absorb accumulated delays.
