What seas are warm and witch seas are cold?

Warm seas generally include the Caribbean Sea, the Red Sea, and the Mediterranean Sea, which are characterized by high temperatures due to their geographical locations and shallow depths. In contrast, cold seas include the Arctic Ocean and parts of the Southern Ocean, where temperatures remain low year-round due to their proximity to polar regions and deep water currents. Additionally, the North Atlantic and North Pacific Oceans can have cold regions influenced by currents like the Labrador Current and the California Current.
