Why is Tamil Nadu experiencing rainfall?
Tamil Nadu is experiencing rainfall due to the Northeast Monsoon, which is characterised by winds blowing from the northeast towards the southern Indian peninsula. These winds pick up moisture from the Bay of Bengal as they move inland, and they bring rain to the coastal areas of Tamil Nadu. The eastern coast of India, including Tamil Nadu, is positioned to receive rainfall from the Northeast Monsoon as the winds blow from the sea to the land.
When is the monsoon expected in Chennai?
The monsoon is expected to arrive in Chennai between June 1 and June 5, 2025. This means that Chennai can expect the first rains of the Southwest monsoon around that time.
