Thiruvananthapuram. The southwest monsoon has now reached the final stage of its return journey and will soon depart the country.

With this, the northeast monsoon will be ready to arrive. During the northeast monsoon, heavy rainfall occurs widely across South India between October and December.

According to the Meteorological Department, several districts in Tamil Nadu recently received good rainfall, including Coimbatore, the Nilgiris, Tenkasi, and Theni. Chennai and surrounding areas also received normal rainfall.

Although the official arrival time of the northeast monsoon is October 1st, the southwest monsoon has been delayed for the past few years due to the delay in its departure.

This year, the southwest monsoon began retreating from parts of western Rajasthan and Gujarat on September 14th, but it has not fully departed even after more than a month.

According to the India Meteorological Department (IMD), during the four-month southwest monsoon season, which lasts from June to September, the country received approximately 8 percent more rainfall than the long-term average. The distribution of rainfall was somewhat uneven.

The northwestern, western, and central parts of the country received more rainfall. Southern India also received 7 percent more rainfall than the normal average, but the eastern and northeastern states received less rainfall. However, heavy rainfall was recorded in Bihar and Bengal during the first week of October.

While this above-average rainfall caused severe flooding in some areas and damaged Kharif crops, water levels in dams and reservoirs increased significantly. This will ensure adequate water is available for the sowing and growth of Rabi crops.
