Bhubaneswar: The India Meteorological Department (IMD) has announced that the southwest monsoon will arrive early over the Andaman Sea, the South Bay of Bengal, and the Andaman and Nicobar Islands. This is happening more than a week ahead of the usual schedule. 
Early Monsoon 2025: IMD Predicts Early Onset Over Andaman Sea, Kerala by May 27

 

Normally, the monsoon reaches the Andaman Sea around May 18-19, but this year, it is expected to arrive today, much sooner than usual. The IMD has also predicted that the monsoon could reach Kerala by May 27, which is earlier than its typical arrival date of June 1. After reaching Kerala, the monsoon usually takes another 10-12 days to advance into Odisha.  
The IMD has stated that weather conditions are favorable for the monsoon to move into parts of the Andaman Sea, the South Bay of Bengal, and the Andaman and Nicobar Islands within the next 24 hours. Over the next four to five days, the monsoon is expected to spread further into the southern Arabian Sea, the rest of the Andaman and Nicobar Islands, the entire Andaman Sea, and some areas of the central Bay of Bengal.  
An early monsoon can have both positive and negative effects. On one hand, it may bring relief from the intense summer heat and help farmers prepare for the upcoming planting season. On the other hand, if the rains are too heavy, they could lead to flooding in some areas.  
The IMD will continue to monitor the monsoon’s progress and update its forecasts. People in the affected regions should stay updated with weather alerts and prepare accordingly.  
This early arrival could also impact other parts of India, as an early onset in the Andaman Sea often indicates a faster advance over the mainland. If the monsoon reaches Kerala by May 27, states like Karnataka, Maharashtra, and Odisha may also experience earlier-than-normal rains.  
Farmers, fishermen, and disaster management teams are advised to keep track of the latest weather reports to plan their activities safely. The IMD will provide further updates as the monsoon continues to develop.
