Final answer:
The southwesterly monsoon can result in stronger and larger waves along affected coastlines.
Step-by-step explanation:
The southwesterly monsoon can have a significant impact on waves. As moisture-laden clouds rise in elevation in the mountains, the water vapor condenses in the form of rain or snow and feeds the streams and basins that flow into major rivers. This increased flow of water can result in stronger and larger waves along the coastlines affected by the monsoon.
