As temperatures soar across India this April, the question is no longer if heatwaves will hit — it’s how prepared we are to survive them.
According to the India Meteorological Department (IMD), several northern states including Delhi, Punjab, Haryana, Rajasthan, and Gujarat are already under heatwave alerts, with temperatures crossing 45°C in some regions. Delhi recorded 40.2°C this week, while Gujarat moved from a red alert to an orange one.
Experts say the Spring season has shrunk, and the Summer heat is arriving earlier every year. February 2025 was India’s hottest February in 125 years, followed by a record-breaking March. Now in April, the country is witnessing heatwaves typically expected in late May.
🔥 Why the Heat is More Dangerous This Year
Doctors across India are reporting a rise in heat-related illnesses, particularly among children, working adults, and the elderly.
Dr. Manjusha Agarwal of Gleneagles Hospital, Mumbai, notes a 2% spike in dehydration, dizziness, respiratory infections, and viral fevers, especially in the 5–65 age group.
Last year, India recorded the highest number of heatwave days in 15 years, with temperatures peaking at 50.5°C in Rajasthan. Government data put the official death toll at 161, but independent estimates suggest over 700 fatalities.
India’s Current Response: Better, But Not Enough
India has made strides in early warnings and response:
-
IMD forecasts are now reliable and issued up to a week in advance.
-
23 states have heat action plans with measures like:
-
ORS distribution
-
Public water stations
-
School/office timing adjustments
-
Awareness campaigns and hospital preparedness
-
Yet experts agree: India is not “heat-proof”. What’s missing are long-term urban cooling strategies, green infrastructure, and technology-driven prediction systems.
🌿 Can India Learn from Singapore’s 3-Step Strategy?
Singapore, once battling similar heat challenges, has become a global model for urban cooling with its three-pronged strategy:
✅ 1. Cool Buildings with Green Design
-
Vertical forests and eco-roofs reduce AC usage by up to 31%
-
Cool paints slash surface temperatures by 2°C
-
Wind corridors direct cooler air into densely packed urban zones
✅ 2. Urban Forests through the LUSH Program
-
Skyscrapers are turned into green towers, creating 300+ hectares of vertical gardens
-
Trees line buildings and streets, cutting heat and shading public spaces
✅ 3. Smart Housing with Cool Paints
-
Government public housing is coated with temperature-reducing paints
-
No energy required, just smart material science
Additionally, Singapore uses DUCT, a digital twin simulation model to predict and prepare for heat flow patterns in real-time — helping them act before the heat becomes deadly.
🌏 The Bigger Lesson: Cooling Cities = Saving Lives
“Singapore’s model shows that cooling cities isn’t just about comfort — it’s about survival.”
says environmentalist Rita Maker.She adds,
“India needs to go beyond reactive measures and adopt sustainable urban planning that lowers local temperatures and improves public health.”
With climate change becoming permanent, experts urge India to view heatwaves as a public health emergency, not just a seasonal inconvenience.
