Delhi’s communities step up as April heatwave breaks records, but long-term climate action still elusive

Amid one of the hottest Aprils on record, Delhi is witnessing a powerful alliance of communities coming together to set up cooling points across the city to deal with deadly heatwave. With temperatures soaring to 40.2°C by the first week of April—well before the usual May-June peak—the 2025 summer has made it clear: extreme heat is no longer a seasonal anomaly, it’s a climate crisis.

On April 28, despite partly cloudy skies, Safdarjung—the city’s base weather station—recorded a scorching 41.3°C, four degrees above normal. This marked the highest temperature of the year so far, surpassing the 41°C heatwave on April 4. It’s also the hottest April day in Delhi since 2022, when the city peaked at 43.5°C on the same date.
In this rising heat emergency, grassroots resilience is proving to be Delhi’s strongest defense. The Delhi Rising campaign, powered by local communities and worker unions, has set up 10 cooling points across high-risk zones like Seemapuri, GTB Nagar, Mukerjee Nagar and Delhi University’s North Campus. Using clay matkas (naturally cooling water pots) and revived public infrastructure, these community-led hydration hubs are not only providing relief but also rekindling civic ownership.

Women in the Kabristan Road neighborhood inaugurated their own cooling station, underlining that this effort isn’t just about surviving heat—it’s about reclaiming public spaces with dignity and care. “This initiative is a beautiful reminder that when communities come together, they can rebuild hope and resilience with their own hands,” said Sunita, a campaigner from Seemapuri.

The community movement is gaining momentum at a time when the Delhi government has rolled out its 2025 Heat Action Plan (HAP) under the guidance of the Delhi Disaster Management Authority and in collaboration with health agencies and expert bodies like NDMA, IMD, and NCDC​. The plan outlines a comprehensive three-tier strategy: early warning systems, public awareness campaigns, and dedicated health sector readiness—including special heat wards in hospitals like AIIMS and RML​.

Hospitals have been advised to create rapid response teams, dedicate cooling zones for heatstroke patients, and stock critical supplies like ORS, IV fluids, and cooling kits. Public messaging campaigns via hoardings, radio, and WhatsApp alerts have been activated, especially targeting vulnerable areas like slums and squatter settlements.
However, while the HAP is commendable for laying out immediate response mechanisms—including heatwave alert systems (yellow, orange, and red alerts)—its focus remains largely short-term. Climate experts and activists argue that what’s missing is a systemic, long-term urban adaptation plan that prepares Delhi for a future where 45°C in April could become a frequent reality.

April 2025 has already proven anomalous: Barmer hit 46.4°C on April 8, and cities across Rajasthan, Gujarat, Maharashtra, and Madhya Pradesh recorded 43°C and above during the first two weeks of the month. Delhi’s early heatwave coincided with a weakening of cooling western disturbances and a climate-change-driven heat index that felt up to 4°C higher than historical trends​.

“The current crisis must be seen as a climate red flag,” said Vaishali Upadhyay, Climate Justice Campaigner at Greenpeace India. “We need heatwaves to be declared as national disasters. Only then can we unlock the funding and policy push for building truly climate-resilient infrastructure—rooftop cooling, greening of urban heat islands, and strengthening early warning systems at the local level.”

Meanwhile, community-led actions like Delhi Rising are not waiting for bureaucracy. Volunteers are restoring defunct public water points, coordinating with local groups like Basti Suraksha Manch, and using creative messaging—from painted matkas to community dialogues—to raise awareness.

“In high-risk areas, access to clean drinking water and shade is not a luxury—it’s a lifeline,” said Ravi, a street vendor at Delhi University. His words capture the urgency of both community resilience and government foresight in a warming world.

As the capital braces for what may be the hottest summer yet, Delhi’s experience offers a clear lesson: short-term relief and long-term planning must go hand in hand. Heat is no longer just a weather event—it’s a socio-political and public health challenge, and it’s here to stay.
