The southwest monsoon is set for a significant revival in the first week of September across India. A well-marked low-pressure area developing over the Bay of Bengal is expected to bring a fresh spell of rain to eastern and northern parts of the country. The India Meteorological Department (IMD) has forecast heavy to very heavy rainfall for several states, offering a crucial boost as the monsoon enters its final month.

  • Monsoon revival expected in the first week of September.
  • A low-pressure area over the Bay of Bengal is the primary cause.
  • Heavy to very heavy rainfall forecast for Eastern and Central India.
  • Parts of North India also expected to receive continued rainfall.

New Delhi: The southwest monsoon is showing strong signs of a renewed push across India, particularly in the opening days of September. A well-marked low-pressure area, currently over the Bay of Bengal, is moving inland, setting the stage for a fresh spell of rain across eastern and northern India. This system is poised to keep the rain belt active as the monsoon season enters its crucial final month.

The India Meteorological Department (IMD) has stated that the system, presently situated over Gangetic West Bengal and adjoining areas of north coastal Odisha and the northwest Bay of Bengal, is expected to move west-northwestwards. This development comes at a critical juncture, as some parts of the country have experienced rainfall deficits, making this revival particularly significant for the agricultural sector and water resources.

Heavy Rain to Lash Central and Eastern India

The strongest spell of rainfall is anticipated across Odisha, Chhattisgarh, Gangetic West Bengal, and Jharkhand. The IMD has forecast heavy to very heavy rainfall over Gangetic West Bengal and Jharkhand on Monday, August 31, 2026, while Odisha and Chhattisgarh are expected to see heavy rain through September 1. Isolated extremely heavy rainfall has also been forecast over Odisha on August 30 and 31, and Chhattisgarh on August 31. The well-marked low-pressure area is likely to move west-northwestwards across north Odisha and Gangetic West Bengal during the next 24 hours.

Rain Returns to North India

The system's broader influence, along with the monsoon trough, is also expected to keep parts of northern India wet. The IMD has forecast isolated to scattered rainfall over Haryana, Chandigarh, Delhi, Punjab, and West Uttar Pradesh from August 31 to September 5. East Uttar Pradesh is likely to remain particularly wet, with heavy rainfall forecast through September 5 and isolated very heavy rain expected on August 31. West Uttar Pradesh is also likely to receive heavy rain through the first week of September. For Delhi and the surrounding northern plains, this indicates that the monsoon is not yet ready to retreat, with intermittent rain continuing into early September, although rainfall intensity will vary.

Why This Matters

BozokMedia analysis shows that this resurgence in the monsoon during its final month is crucial for India's agrarian economy. Rainfall in September is vital for the maturation of several kharif crops and for replenishing groundwater levels and reservoirs ahead of the drier months. However, the forecast for isolated extremely heavy rainfall in some regions also raises concerns about potential flash floods and waterlogging, which could adversely affect infrastructure and human life. This also highlights the uneven distribution of rainfall, where some regions might experience excessive downpours while others still face deficits.

Meteorological experts suggest that this revival underscores the dynamic nature of the Indian monsoon, where late-season rains often prove decisive for regional water balance.
Did You Know?: The Indian monsoon is one of the largest seasonal weather systems in the world, responsible for over 70% of India's annual rainfall and serving as a lifeline for the country's economy, particularly agriculture.
