The monsoon winds blow in summer from South West to North East.

The monsoon winds blow in summer from South West to North East as during summer, the sun is directly above the Tropic of Cancer, the main landmass of Asia develops low pressure. The surrounding seas being cooler, develop high pressure. Since the winds blow over the oceans, they pick up a lot of moisture and give heavy rainfall in South Asia. These are known as southwest monsoon winds as they blow from southwest to northeast.
