New Delhi: The southwest monsoon is expected to arrive over Kerala on June 4, 2026, after a brief delay, according to the India Meteorological Department (IMD). The onset will mark the official beginning of India’s annual rainy season, which is crucial for agriculture, water resources and the overall economy.
The IMD has forecast widespread rainfall activity across southern India over the coming week, with Kerala likely to experience the heaviest impact as the monsoon advances into the region.
Several parts of Kerala are expected to receive heavy to very heavy rainfall over the next six to seven days. Rainfall amounts between 7 centimetres and 20 centimetres have been predicted at isolated locations, prompting authorities to closely monitor weather conditions and preparedness measures.
The weather agency has also predicted isolated heavy rainfall over parts of Tamil Nadu and Karnataka as the monsoon system strengthens and spreads across southern states.
The arrival of the southwest monsoon is one of the most significant weather events in India, providing nearly 70 per cent of the country’s annual rainfall. The seasonal rains play a vital role in supporting agriculture, replenishing reservoirs, maintaining groundwater levels and meeting water demands across the country.
Meteorologists expect rainfall activity to gradually intensify and expand to other regions as the monsoon progresses northward in the coming weeks. Farmers and water resource managers are closely watching the monsoon’s movement, as its performance has a direct impact on crop production and rural livelihoods.
Residents in Kerala and adjoining states have been advised to remain alert for heavy rainfall, waterlogging and possible disruptions in low lying areas. Authorities are expected to issue local advisories as weather conditions evolve.
