The national capital has experienced a significant, albeit temporary, improvement in its air quality, registering a ‘satisfactory’ Air Quality Index (AQI) of 96 on Friday.
This welcome change comes amidst a spell of unseasonal rainfall and thunderstorms that have swept across the city, bringing much-needed respite from the pre-monsoon heat. While the meteorological phenomena have offered a brief environmental dividend, they have simultaneously exposed critical vulnerabilities in Delhi’s urban infrastructure, underscoring the complex interplay between climatic variability and the city’s journey towards becoming a truly eco-friendly, sustainable, and equitable metropolis. The India Meteorological Department (IMD) recorded a minimum temperature of 26.4 degrees Celsius on Friday, with relative humidity at 69 per cent by 8:30 am, and a maximum temperature forecast to touch 37 degrees Celsius. These conditions stand in stark contrast to Delhi’s notorious hot and often polluted summers. According to the Central Pollution Control Board (CPCB), an AQI between 51 and 100 is classified as ‘satisfactory’, a marked improvement from the ‘poor’ or ‘very poor’ categories often witnessed in the capital.

However, the very weather system that brought relief on Wednesday also triggered widespread disruption. Heavy rain and thunderstorms unleashed havoc across parts of the national capital, leading to flight delays, metro disruptions, and significant traffic jams that brought large swathes of the city to a standstill. Power outages were also reported in several areas, with Tata Power Delhi Distribution Limited (DDL) confirming temporary electricity cuts as a safety measure after trees and branches damaged electric cables. Furthermore, the intense weather uprooted trees and damaged vehicles, while waterlogging was extensively reported at critical locations such as near the Akshardham Flyover, Sikandra Road, and under Tilak Bridge near ITO. These recurrent incidents of urban paralysis during heavy rainfall underscore the urgent need for a more robust and resilient urban infrastructure. Effective stormwater management systems, well-maintained drainage networks, and a resilient power grid are paramount for a city striving for sustainability. The socio-economic impact of such disruptions is far-reaching, affecting daily commuters, hindering access to work and essential services, and disproportionately burdening vulnerable populations who rely heavily on uninterrupted public transport and civic amenities. Achieving gender-neutral and equitable urban environments necessitates infrastructure that can withstand climatic shocks without compromising access or safety for any segment of the population.
The IMD has forecast that rain and thunderstorms are likely to persist throughout the week, specifically from May 20-25, accompanied by strong surface winds. These conditions are expected to continue offering some respite from the intense heat, with maximum temperatures predicted to range between 39 degrees Celsius and 41 degrees Celsius, and no heatwave conditions anticipated during this period. While this meteorological outlook provides welcome relief from the debilitating summer heat, it simultaneously accentuates Delhi’s ongoing challenge to adapt to changing climate patterns. Ultimately, Delhi’s experience with these recent rains presents a dual narrative: a temporary environmental reprieve juxtaposed against significant operational challenges. It highlights that while natural forces can momentarily improve environmental metrics, the pathway to a truly zero-net carbon, eco-friendly, and sustainable city lies in proactive urban planning, robust infrastructure development, and consistent environmental governance. Such measures are essential to ensure that climatic variations do not compromise the quality of life or the equitable provision of services for its rapidly growing population.
