India is experiencing an accelerated and intensified southwest monsoon this year, as the India Meteorological Department (IMD) confirmed that the monsoon has officially covered the entire country by June 29, 2025—a full nine days ahead of its typical schedule of July 8.

This early and widespread onset has brought heavy to very heavy rainfall across vast regions, sparking floods and flood-like conditions in both western and eastern states, and catching many off guard with its swiftness.

The monsoon first arrived in Kerala on May 24, over a week earlier than the norm. From there, it surged northward rapidly, reaching Mumbai by May 26—the city’s earliest monsoon arrival in 25 years. A journey that typically takes around 10 to 11 days was completed in just two.

Even before the official onset, many parts of India had already started receiving intense pre-monsoon showers in May, largely due to an unusual spike in western disturbances. These Mediterranean-origin storm systems, which usually occur once or twice in May, appeared five to seven times this year, according to IMD data. The result was unseasonal, and often torrential, rainfall sweeping across multiple states.

Early June's Toll on the Northeast

As the monsoon gathered strength, the northeastern states bore the initial brunt. Persistent rainfall from late May continued into June, triggering floods and landslides. A report by humanitarian network Sphere India revealed that at least 50 people lost their lives, while nearly 15,000 hectares of crops were devastated across the region.

Now, with the monsoon fully spread across the country, meteorologists warn that the coming days will bring sustained heavy rainfall to several regions — powered by active low-pressure systems and cyclonic circulations forming over land and sea.

Rainfall Snapshot and Weather Systems at Play

The past 24 hours have brought intense rain across diverse regions, including Uttarakhand, Madhya Pradesh, the Andaman & Nicobar Islands, Punjab, Haryana, West Rajasthan, Uttar Pradesh, and others.
Simultaneously, squally winds between 40–70 kmph and thunderstorms have battered parts of Kerala, Bihar, Gujarat, and Maharashtra.

The IMD has identified multiple weather systems influencing this surge:

• A low-pressure area has formed over Kutch and nearby areas, due to an upper-air cyclonic circulation over Saurashtra and the northeast Arabian Sea.

• Another cyclonic circulation sits over south-central Uttar Pradesh, while one more impacts Bangladesh and Gangetic West Bengal, likely to form a low-pressure area and move west-northwest over Jharkhand and Odisha.

• An east-west trough and additional cyclonic circulations over the northeast are further fueling instability.

What’s Ahead — Regional Forecast Highlights

West India:

• Expect heavy to very heavy rainfall in Konkan & Goa, Madhya Maharashtra’s Ghat areas, and Gujarat over the next 7 days.

• Light to moderate rainfall will prevail in most areas.

Northwest India:

• Uttarakhand and Uttar Pradesh may see extremely heavy rainfall (>20 cm in 24 hours) on June 30.

• Other states like Himachal Pradesh, Rajasthan, Punjab, and Haryana will continue to experience scattered heavy showers through early July.

• Thunderstorms with gusty winds (30–40 kmph) are likely across the region.

Central & East India:

• Regions such as Madhya Pradesh, Odisha, Jharkhand, Chhattisgarh, Vidarbha, and Bihar will face persistent heavy to very heavy rainfall from June 28 to July 4.

• Gangetic West Bengal is also expected to witness intense rain on June 29–30.

Northeast India:

• The region remains on alert with ongoing moderate to heavy rain.

• Very heavy rainfall is forecast over Arunachal Pradesh, Assam, Meghalaya, and Nagaland between July 1 and July 4.
