Are sea breezes or land breeze caused by warm ocean water?

Sea breezes are caused by the temperature difference between the land and sea, where warm air rises over the land during the day, causing cooler air from the sea to move in. Land breezes are caused by the temperature difference at night, where the land cools faster than the sea, causing the air over the land to be cooler and denser, thus moving towards the warmer sea. Warm ocean water plays a role in providing the temperature contrast necessary for these breezes to occur.
