The ocean that borders the east coast of Africa is the Indian Ocean. This ocean is the third-largest in the world and is vital for global trade, connecting Africa to Asia and Australia. The Indian Ocean is characterized by its warm waters, diverse marine life, and significant trade routes that have shaped the economies and histories of coastal nations. Additionally, the ocean impacts weather patterns and climate in the region, and areas along its coast, such as the Swahili Coast, are known for their rich cultural heritage, shaped by centuries of maritime trade.
