Why did South Asian merchants prefer to travel to Africa in the winter months?

South Asian merchants preferred to travel to Africa in the winter months primarily due to favorable wind patterns. The monsoon winds in the Indian Ocean significantly influenced maritime trade routes. During the winter months, the northeasterly winds blow from the Arabian Sea towards the African coast, creating optimal sailing conditions for vessels headed to East Africa. This seasonal shift allowed merchants to make the journey more efficiently and safely, reducing travel time and increasing the likelihood of successful trade ventures.

The other options, while they may have some connection to the overall trade dynamics between South Asia and Africa, do not directly explain why winter travel was particularly advantageous. Access to better trade goods, for instance, may vary regardless of the season and does not account for the logistical challenges of long-distance maritime travel. Political alliances and cultural exchanges, while important aspects of trade relationships, do not specifically relate to navigation and sailing conditions as influenced by seasonal winds.
