The ocean currents greatly affect the weather. Bodies of water absorb heat and they also release coolness to land. The currents of the oceans help distribute the heat and coolness to different areas. Currents from the equator are much hotter compared to the ocean currents near the poles.
Thus, ocean currents help bring warm or cool air to a land. The absorbed warmth of the currents from the land form clouds and will then precipitate to cool-off that area. It might be scorching hot during daytime but with the help of ocean currents, a possible rainfall will occur at night or the next day due to their movement and absorption of heat.
