Climate 2025: The Extreme Weather Events That Defined India’s Year

2025: The Year India Faced Climate Reality.

As 2025 winds down, one thing is impossible to ignore: India just lived through one of its most alarming climate years on record. From blistering heat to devastating storms, extreme weather didn’t just punctuate the year — it defined it.

A Year of Relentless Extremes

The brutality began early.
April’s heatwave pushed Delhi past 40°C — a full 4°C hotter than comparable heatwaves before 1987. A ClimaMeter study found that human-driven climate change was the clear accelerator, affecting large parts of India and Pakistan.

Then came Cyclone Montha, leaving a trail of destruction worth ₹53 billion, with Andhra Pradesh hit hardest.

Tamil Nadu reeled under intense rainfall, while Odisha, West Bengal, Puducherry, and other coastal regions remained on continuous alert. In the north, severe cold waves and fog brought the region to a standstill.

Extreme Weather on 99% of Days

November’s Climate India 2025 report by the Centre for Science and Environment (CSE) and Down To Earth delivered the harshest truth yet:

For 99% of the first 273 days of 2025, India experienced some form of extreme weather. Heatwaves, cold waves, lightning, storms, heavy rainfall, floods, landslides — almost no day was spared.

The toll:

• 4,064 deaths
• 9.47 million hectares of crops damaged

Northwest India saw the most extreme-weather days (257), followed by the east and northeast (229)

And as always, experts warn these numbers are conservative due to incomplete reporting.

The Human and Economic Toll

Beyond statistics, the human cost was staggering.
Madhya Pradesh recorded the highest fatalities at 532, followed by Andhra Pradesh (484) and Jharkhand (478).

The damage to livelihoods was widespread:

• 99,533 houses destroyed
• 58,982 animals lost
• Millions of farmers pushed further into uncertainty
• Breaking Records for All the Wrong Reasons

2025 shattered climate records at an unsettling pace:

January: Fifth driest since 1901

February: Warmest in 124 years

September: Seventh-highest mean temperature ever

Monsoon: All 122 days saw at least one extreme weather event

The monsoon also became deadlier than ever, accounting for 3,007 of the 4,064 deaths — the highest monsoon-related fatalities since 2022.

Rising temperatures during the monsoon, explains Kiran Pandey of CSE, disrupt the entire climate system, triggering unpredictable rainfall patterns, floods, droughts, and threats to agriculture, food security, and public health.

A Warning from Climate Leaders

CSE director Sunita Narain put it bluntly:
“We no longer need to count just the disasters, but understand the scale.”

Her message is clear:
Unless global emissions fall drastically, adaptation alone won’t save us.
“The disasters of today,” she warns, “will become the new normal of tomorrow.”
