The Northern East Coast is most affected by the North Atlantic Drift, a warm ocean current.

The North Atlantic Drift, an extension of the Gulf Stream, brings warm water from the tropics to the northern Atlantic, significantly influencing the climate along the U.S. Northern East Coast. This current helps moderate temperatures, keeping winters milder and summers cooler compared to areas further inland. Cities like New York and Boston experience this moderating effect, which results in a more temperate climate. The influence of the North Atlantic Drift is key in shaping the region’s weather patterns, making it warmer in winter than other northern areas.
