The Southwest monsoon has reached major parts of Northeast India, including Tripura, Mizoram, Nagaland, Manipur and Assam. IMD forecasts complete monsoon coverage across the region within the next 2-3 days. Normal to above-normal rainfall is expected, offering significant benefits to agriculture, water resources and environmental sustainability.
The Southwest monsoon has finally arrived in substantial parts of Northeast India, marking a significant development for the region’s weather and agricultural sectors. According to officials of the India Meteorological Department (IMD), the monsoon advanced into Tripura, Mizoram, Nagaland, Manipur and parts of Assam and Arunachal Pradesh on Sunday, two days later than its normal onset date.
Meteorological experts have indicated that favourable atmospheric conditions are currently prevailing across the region, enabling the monsoon system to advance further. The IMD has forecast that the Southwest monsoon is likely to cover all the Northeastern states within the next two to three days, bringing widespread rainfall and improving prospects for the agricultural season.
Officials noted that the monsoon’s arrival this year has been slightly delayed compared to 2025, when it reached most parts of the Northeastern region on May 26. Despite the delay, weather experts remain optimistic about rainfall prospects for the coming months.
The IMD stated that conditions remain highly favourable for further advancement of the monsoon into the remaining parts of Northeast India, along with some areas of Sub-Himalayan West Bengal and Sikkim. Several other regions of the country, including the Andaman and Nicobar Islands, Karnataka, Konkan and Goa, Lakshadweep, Maharashtra, Tamil Nadu and Puducherry, are also expected to receive rainfall in the coming days.
Weather officials have projected that rainfall during the four-month Southwest monsoon season, which extends from June to September, is likely to remain normal to above normal across the Northeastern states. This forecast is expected to bring relief to farmers and residents who depend heavily on seasonal rainfall for agriculture and water resources.
Experts have also addressed concerns regarding the possible development of strong El Niño conditions during the latter half of 2026. While El Niño events are often associated with reduced rainfall and higher temperatures in many parts of India, meteorologists believe the Northeast may remain relatively insulated from severe impacts due to its dense forest cover, unique geographical features and favourable climatic conditions.
According to weather specialists, one of the strongest El Niño episodes on record could emerge later this year, potentially influencing weather patterns across Asia and the Americas. However, the diverse topography and ecological characteristics of the Northeastern region are expected to support continued rainfall activity despite broader climatic challenges.
The arrival of the Southwest monsoon is particularly important for the agrarian economy of the Northeast. A large portion of the population relies on rain-fed agriculture for their livelihoods. Adequate rainfall during the monsoon season is essential for crop cultivation, groundwater recharge, reservoir replenishment and maintaining ecological balance.
Agricultural experts believe that timely and sufficient rainfall will help farmers begin cultivation activities, improve crop productivity and strengthen food security across the region. In addition, healthy monsoon conditions are expected to contribute to better water availability and enhanced environmental conditions.
