 The South West and North East Monsoon winds bring rains in india.
The South-West Monsoon winds blows (from the south-west direction) from the Indian Ocean onto the Indian landmass during the months of June through September. These are generally rain-bearing winds, blowing from sea to land, and bring rains to most parts of the subcontinent. Subsequently later in the year, around October, these winds reverse direction and start blowing from a north-easterly direction. Given their land to sea flow, from subcontinent onto the Indian Ocean, they have less moisture and bring rain to only limited parts of India like Andhra Pradesh and Tamil Nadu.
