Rainfall Deficit

India has seen 20% below normal rainfall since June 1, with overall June precipitation also expected to be subpar, per the India Meteorological Department (IMD).

Early Monsoon Halt

The monsoon hit mainland India two days early, but made no progress between June 12 and 18, extending the heatwave in north India.

Monsoon Advancement

Conditions now favour the monsoon advancing into Maharashtra, Chhattisgarh, Odisha, Andhra Pradesh, Bihar, and Jharkhand in the next few days.

Regional Rainfall

From June 1-18, rainfall was 20% below normal, with the northwest receiving 70% less, central India 31% less, and the south peninsula 16% more than average.

Early Cyclone Impact

The southwest monsoon reached Nicobar Islands on May 19, Kerala and northeastern states by May 30, aided by Cyclone Remal.

Monsoon Coverage

By June 12, the monsoon covered Kerala, Karnataka, Goa, Andhra Pradesh, Telangana, southern Maharashtra, and some parts of southern Chhattisgarh and Odisha.

Monsoon Limit

As of June 18, the northern limit of the monsoon was fixed at Navsari, Jalgaon, Amravati, Chandrapur, Bijapur, Sukma, Malkangiri, and Vizianagaram.

Sub-Divisional Rainfall

Between June 1-18, 11 meteorological sub-divisions received normal to excess rainfall, while 25 experienced deficient to large deficient rainfall.

June Forecast

June is likely to see below-normal rainfall (less than 92% of LPA), with the southern peninsula and parts of northeast India expected to fare better.

Core Monsoon Zone

India's core monsoon zone, crucial for rain-fed agriculture, is predicted to receive above-normal rainfall this season, boosting crop prospects.

Reservoirs and El Nino

Reservoirs are at 22% capacity amid heatwaves. El Nino, causing weaker monsoon winds, may transition to La Nina by August-September, improving rainfall.
