Winds that give maximum
rainfall to India are south-west monsoon. These winds bring rains towards the
end of the summer due to high pressure built in the Indian Ocean. As they enter
India they divide into branches.
The Arabian Sea Branch of
the Southwest Monsoon first hits the Western Ghats of the coastal
state of Kerala, India, thus making this area first to receive rain from
the south-west monsoon. This branch of the monsoon moves northwards towards
western side.
Bay of Bengal branch of south-west monsoon reaches north-east of India.
