The Gulf Stream brings warm, moist air to the Atlantic Coast, moderating temperatures and increasing humidity.

The Gulf Stream, a warm Atlantic Ocean current, flows northward along the eastern U.S. coast, carrying warm, moist air from the tropics. This current moderates temperatures along the Atlantic Coast, helping keep winters milder and summers more humid. The warmth of the Gulf Stream also increases coastal precipitation, as the moist air cools and condenses, creating clouds and rain. This effect makes the climate of the eastern U.S. warmer and more humid compared to regions at similar latitudes elsewhere, significantly influencing weather patterns and supporting lush vegetation along the coast.
