Which City Receives the Monsoon First in India?

The city that is commonly regarded as receiving the Southwest Monsoon first in India is Thiruvananthapuram (Trivandrum), Kerala. Located on the southwestern coast of India, Thiruvananthapuram is among the first major Indian cities to experience the arrival of the Southwest Monsoon as it enters the Indian mainland through Kerala.

Why Does the Monsoon Arrive First in Kerala?

The Southwest Monsoon originates over the Indian Ocean and Arabian Sea. As the moisture-laden winds move northward, they first strike the Kerala coast before advancing across the rest of the country. The India Meteorological Department (IMD) uses a network of weather stations across Kerala and nearby regions to officially declare the onset of the monsoon over India.

The normal onset date of the Southwest Monsoon over Kerala is around 1 June, although the actual date can vary from year to year depending on weather conditions. (India Meteorological Department)
