A Heatwave Action Plan is a preparedness and response strategy designed to reduce heat-related deaths, illnesses and livelihood disruption during periods of extreme heat.

It brings together early warning, public awareness, health preparedness, water supply, work-hour regulation, protection of vulnerable groups and coordination among government departments.

From Delhi’s graded heat alerts to Rajasthan’s cooling stations for informal workers, several states have institutionalised heat governance through Heat Action Plans (HAPs), disaster financing mechanisms, and urban cooling policies. According to the Union government, over 250 cities and districts across 23 heat-prone states have operational HAPs.

Rationale for Heat Action Plan (HAP)

Many States are affected during the heat wave season, such as Andhra Pradesh, Telangana, Odisha, Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Uttar Pradesh, Maharashtra, Karnataka, Tamil Nadu, Bihar, Jharkhand, West Bengal, Haryana, Punjab and Delhi.
The actual numbers of deaths resulting from heat waves are higher than the reported numbers.
- Mostly the deaths in rural areas due to heat waves are often not reported.
The booming service sector with a large number of vegetable vendors, auto repair mechanics, cab drivers, construction workers, road side kiosk operators etc particularly vulnerable to the heat wave conditions.
Though the richer sections of India have the ability to cope with higher temperatures by investing in air conditioners and coolers, the poorer population remains vulnerable to the higher temperatures. Therefore, it is not surprising that these workers, homeless people and the elderly constitute the majority of heat wave casualties in India.
These heat wave related deaths can be prevented with an evidence based plan, effective implementation and frequent updating in line with recent scientific development.
- Unlike sudden disasters, heatwaves develop gradually. Therefore, timely preparedness can significantly reduce deaths and health impacts.
Heatwaves are becoming more frequent, intense and prolonged due to climate change, urban heat island effect, land degradation and rapid urbanisation.

Hence, a national level strategy and plan to combat heat waves should be developed. A comprehensive heat preparedness and response requires involvement from government authorities, non-governmental organizations and civil society.

Major Components of Heatwave Action Plan

Heatwave Early Warning System
- Early warning is the first step in heatwave management.
- Forecasts and alerts should be issued based on maximum temperature, minimum temperature, humidity, heat index, duration of heat and local vulnerability.
- Warnings should reach people through SMS, television, radio, newspapers, mobile apps, social media, local bodies, health workers, schools, panchayats and community volunteers.
Colour-Coded Alerts
- Heatwave alerts may be issued in colour-coded form so that people and authorities understand the severity.
- Green may indicate normal conditions, yellow may indicate heat alert, orange may indicate severe heat conditions and red may indicate extreme heat requiring urgent action.
- This helps in graded preparedness and response.
Public Awareness Campaigns
- People should be informed about heat risks and safety measures before and during summer.
- Awareness should include drinking enough water, avoiding direct sunlight, wearing loose cotton clothes, using ORS, staying in shade, avoiding strenuous work during peak afternoon hours and recognising symptoms of heat stroke.
Identification of Vulnerable Groups
- The plan should identify people who are most at risk.
- These include elderly persons, children, pregnant women, persons with disabilities, people with chronic diseases, outdoor workers, construction labourers, street vendors, traffic police, slum dwellers, homeless persons and people without access to cooling.
Health System Preparedness
- Hospitals, primary health centres and ambulances should be prepared before the heatwave season.
- This includes heat stroke treatment protocols, emergency beds, ORS, IV fluids, cooling arrangements, ice packs, trained medical staff, ambulance readiness and surveillance of heat-related illness and deaths.
Drinking Water Arrangements
- Safe drinking water should be made available in public spaces, bus stands, railway stations, markets, schools, hospitals, worksites, slums and vulnerable settlements.
- Water kiosks, tankers, repair of hand pumps, public water points and mobile water supply should be ensured during peak heat periods.
Work-Hour Regulation
- Outdoor work should be avoided during peak heat hours, especially in the afternoon.
- Construction work, MGNREGA work, street vending, agriculture work, delivery work and other outdoor activities should be shifted to early morning or evening wherever possible.
- Employers should provide shade, drinking water, rest breaks and first-aid support.
School Safety Measures
- Schools should avoid outdoor activities during heatwave periods.
- School timings may be adjusted, and students should have access to drinking water, shaded areas, first-aid support and awareness on heat safety.
Cooling Centres and Heat Shelters
- Cooling centres should be set up in public buildings, community halls, schools, anganwadi centres and other shaded spaces.
- These are especially important for homeless persons, elderly persons, slum dwellers, migrant workers and people living in poorly ventilated houses.
Urban Heat Reduction Measures
- The plan should include long-term urban cooling measures such as tree plantation, shaded streets, urban forests, parks, green roofs, cool roofs, reflective paints, ventilation corridors, restoration of water bodies and reduction of concrete-dense surfaces.
Cool Roof Programme
- Cool roofs reduce indoor temperature by reflecting sunlight.
- They are especially useful for poor households, slums, schools, anganwadi centres and low-income settlements with tin or concrete roofs.
- White paint, reflective coating, roof insulation and locally available cooling materials can reduce heat stress.
Community-Based Preparedness
- Local volunteers, ASHA workers, anganwadi workers, NGOs, RWAs, panchayats and ward committees should help spread warnings, identify vulnerable persons, distribute water and ORS, support elderly persons and guide people to cooling centres.
Heat-Health Surveillance
- Authorities should monitor heat-related illnesses and deaths.
- Hospitals should report cases of heat cramps, heat exhaustion, heat stroke, dehydration and heat-related mortality.
- This helps improve future planning and identify high-risk areas.
Inter-Departmental Coordination
- Heatwave management requires coordination among health departments, disaster management authorities, municipal bodies, labour departments, education departments, water supply agencies, power departments, transport agencies, police and local bodies.
- Clear roles should be assigned before the heatwave season.
Agriculture and Livestock Advisory
- Farmers should receive advisories on irrigation scheduling, mulching, soil moisture conservation, heat-tolerant varieties and crop protection.
- Livestock should be protected through shade, drinking water, ventilation, veterinary care and avoidance of grazing during peak heat hours.
Power Supply Preparedness
- Electricity demand increases during heatwaves.
- Power departments should prepare for peak load and ensure backup electricity for hospitals, water supply systems, cooling centres and emergency services.
Emergency Response Protocol
- The plan should clearly mention what action will be taken during yellow, orange and red alerts.
- This may include opening cooling centres, changing school timings, restricting outdoor work, increasing water supply, deploying ambulances, issuing advisories and activating emergency control rooms.

Challenges in Heat Action Plans

Lack of Local Context and Thresholds: Many HAPs rely on generic, national-level temperature thresholds from the India Meteorological Department (IMD) rather than accounting for local factors like humidity, wind, and urban heat island effects.
Weak Legal and Financial Framework: Plans rarely have legal backing or dedicated funding, which leads to poor compliance and difficulties in implementation.
Inadequate Vulnerability Assessments: Most plans do not map specific local vulnerability, frequently leaving out large, highly exposed demographics such as informal laborers, outdoor workers, and low-income slum residents.
Overemphasis on Reactive Measures: The primary focus remains on temporary measures like setting up water kiosks or issuing health advisories, with little investment in climate-resilient architecture, tree planting, or passive cooling
Resource Constraints: Many regions lack the funding and infrastructure necessary for widespread implementation of HAPs, particularly in rural and lower-income areas.
Many plans remain on paper and are not implemented effectively.
- There are gaps in vulnerability mapping, last-mile communication, occupational safety enforcement, heat-health data, urban cooling, water supply and protection of homeless persons.
Insufficient Focus on Rural Areas: While urban areas receive more attention, rural communities with significant exposure to heatwaves often lack adequate support, healthcare access, and awareness programs.
Limited Community Engagement: Awareness campaigns often fail to engage communities actively, particularly in vulnerable areas. Greater community participation is needed to ensure that HAPs are locally relevant and effective.

Effectiveness of India’s Heat Action Plans in Mitigating Heatwave Effects

Early Warning Systems and Forecasting:
- The India Meteorological Department (IMD) issues heatwave alerts in collaboration with local governments, enabling timely dissemination of heat advisories. This early warning system has improved preparedness, allowing people to take preventive measures.
- However, the reach and accessibility of these warnings, particularly in rural and remote areas, remain limited, affecting their effectiveness in safeguarding vulnerable communities.
Public Awareness Campaigns:
- Many state and city-level HAPs include awareness programs to educate people on protective measures, such as staying hydrated, wearing loose clothing, and avoiding outdoor activities during peak heat hours.
- While awareness has increased in urban areas, rural and lower-income populations often lack adequate knowledge and resources to implement these measures, indicating a need for better targeted and culturally sensitive awareness campaigns.
Healthcare System Preparedness:
- HAPs aim to strengthen the healthcare infrastructure by training healthcare providers in recognizing and treating heat-related illnesses, ensuring availability of cooling facilities, and equipping health centers with essential medical supplies
- However, challenges such as limited healthcare facilities in rural areas and resource constraints in overstretched urban hospitals impact the effectiveness of these initiatives, particularly during prolonged or intense heatwaves.
Cooling Centers and Water Supply:
- Some cities, including Ahmedabad and Nagpur, have set up cooling centers in public spaces and ensured accessible drinking water stations during extreme heat periods. These centers provide respite to vulnerable populations, including the homeless and laborers.
- However, cooling centers are limited to certain cities, and scaling up such initiatives nationwide remains a challenge, especially in resource-poor regions.
Urban Planning and Green Infrastructure:
- HAPs encourage measures like planting trees, creating green spaces, and improving urban planning to reduce the urban heat island effect. In cities like Ahmedabad, initiatives to increase green cover have shown positive results in mitigating heat impact.
- Yet, green infrastructure initiatives are often limited in scope and implementation, particularly in rapidly urbanizing areas, where concrete and asphalt dominate the landscape, intensifying heat absorption.

Way Forward for Strengthening Heat Action Plans

Localise Heat Thresholds
- Heat Action Plans should not depend only on broad national-level temperature thresholds.
- Local thresholds should be prepared by considering humidity, night-time temperature, wind speed, urban heat island effect, local climate, housing conditions and population vulnerability.
- This will make alerts more accurate and context-specific.
Strengthen Legal and Financial Backing
- Heat Action Plans should have clear legal status, dedicated funding and defined institutional responsibilities.
- Without funds and accountability, HAPs remain advisory documents rather than actionable disaster management tools.
Improve Vulnerability Mapping
- Cities and districts should map heat-prone zones and vulnerable groups.
- This should include slums, informal workers, construction labourers, street vendors, traffic police, elderly persons, children, pregnant women, persons with disabilities, homeless persons and people with chronic diseases.
Link Alerts with Clear Action Protocols
- Heat alerts should not only inform people about rising temperature.
- Each alert level should trigger specific actions such as opening cooling centres, increasing water supply, changing school timings, regulating outdoor work, deploying ambulances and activating health teams.
Strengthen Last-Mile Communication
- Warnings should reach people in simple local language through SMS, radio, television, mobile apps, public announcements, ASHA workers, anganwadi workers, RWAs, panchayats, ward committees and community volunteers.
- Special attention should be given to people without smartphones or regular internet access.
Focus on Long-Term Heat Reduction
- Heat Action Plans should move beyond temporary measures like water kiosks and advisories.
- They should include cool roofs, tree plantation, shaded streets, urban forests, restoration of lakes and ponds, climate-sensitive housing, green corridors and passive cooling in buildings.
Protect Outdoor Workers
- Work-hour regulation should be strictly implemented during severe heat.
- Outdoor workers should get shade, drinking water, rest breaks, ORS, first-aid support and flexibility to work during cooler hours.
- Labour departments, contractors and employers should be made accountable.
Strengthen Health System Preparedness
- Hospitals, PHCs and ambulances should be prepared before the heat season.
- They should have trained staff, heat stroke treatment protocols, ORS, IV fluids, cooling arrangements, emergency beds and heat-health surveillance systems.
Improve Rural Heat Preparedness
- Heat Action Plans should not focus only on cities.
- Rural areas also need drinking water support, agricultural advisories, livestock protection, health outreach, shade facilities, awareness programmes and support for farm labourers.
Ensure Community Participation
- Local communities should be actively involved in planning and implementation.
- Community groups can help identify vulnerable households, spread alerts, support elderly persons, manage water points and guide people to cooling centres.
Integrate Heat Risk with Urban Planning
- Master plans, housing schemes, transport planning and building by-laws should include heat-resilience measures.
- Cities should reduce concretisation, protect open spaces, promote ventilation corridors, increase green cover and make cool roofs mandatory in vulnerable settlements.
Improve Data and Monitoring
- Heat-related illnesses and deaths should be properly recorded.
- Local heat maps, health data, mortality data, water-stress data and occupational exposure data should be used to update Heat Action Plans every year.
Promote Inter-Departmental Coordination
- Heatwave management requires coordination among disaster management authorities, municipal bodies, health departments, water supply agencies, labour departments, education departments, power departments, transport agencies and local bodies.
- A clear nodal agency and command structure should be defined.

Heat Action Plans must move from generic advisories to localised, funded, legally backed and action-oriented plans. They should combine early warning, health preparedness, occupational safety, community participation, rural outreach, vulnerable-group protection and long-term urban cooling. With climate change increasing heat risks, HAPs should become a core part of India’s disaster resilience and climate adaptation strategy.
