A study by IPE Global and Esri India reveals that climate change is set to trigger a dramatic escalation in extreme rainfall events across India, compounding the country’s already severe weather challenges.
As global temperatures rise, Indian cities and rural districts are bracing for a future where heavy, erratic rains and heatwaves will become the new normal, with profound implications for lives, livelihoods, and infrastructure.
According to the study, the intensity, frequency, and unpredictability of extreme heat and rainfall events have surged alarmingly over the past three decades. Between 1993 and 2024, India experienced a 15-fold increase in extreme heatwave days during the March–May and June–September periods.
Even more concerning is the fact that the last decade alone saw a 19-fold spike in such events. The study projects that by 2030, major urban centres — including Mumbai, Chennai, Delhi, Surat, Thane, Hyderabad, Patna, and Bhubaneswar—will witness a two-fold increase in heatwave days.
However, it is the anticipated rise in extreme rainfall that is especially troubling: eight out of ten Indian districts are expected to experience multiple instances of erratic and intense rains by 2030.
The research highlights a clear trend: as heatwave hotspots expand, so too does the likelihood of incessant and unpredictable rainfall. Coastal districts, both on the eastern and western coasts, are already experiencing more frequent and erratic downpours, a pattern set to intensify in the coming years.
The study estimates that the frequency of extreme rainfall events could rise by as much as 43% over current levels, driven by microclimatic changes and local drivers such as land-use change, deforestation, and encroachment on mangroves and wetlands.
Abinash Mohanty, Head of the Climate Change and Sustainability Practice at IPE Global and lead author of the study, emphasized the urgency of action: “The study and its stark findings suggest how climate change has exposed India to extreme heat and rainfall, and the situation is going to be grimmer and harsher by 2030, with the majority of urban centers impacted the most.”
He further warned that meteorological phenomena like El Nino and La Nina are gaining stronger momentum, resulting in abrupt surges in climate extremes such as floods, cyclones, storm surges, and extreme heat.
The study calls for a paradigm shift in India’s approach to climate resilience. It recommends hyper-granular risk assessments, the establishment of Climate Risk Observatories, and the appointment of heat-risk champions within district disaster management committees. These measures, it argues, are essential to safeguard agriculture, industry, and infrastructure from the mounting threats posed by climate change.
According to Ashwajit Singh, Founder and Managing Director of IPE Global, “Only then can India truly emerge as the climate solutions capital to the world”.
