Why do cities on the east coast have warmer climates then cities on the west coast at similar latitudes?

Cities on the east coast generally have warmer climates than those on the west coast at similar latitudes due to ocean currents and prevailing winds. The Gulf Stream, a warm ocean current, flows northward along the east coast, raising temperatures in coastal areas. In contrast, the west coast is influenced by the cold California Current, which can lead to cooler temperatures. Additionally, the east coast experiences more humidity, while the west coast often has a drier climate, further contributing to the perceived temperature differences.
