North India is currently facing a double blow from a severe heatwave and rapidly deteriorating air quality. The India Meteorological Department (IMD) has issued an ‘Orange Alert’ for 13 districts in Uttar Pradesh, including key cities such as Lucknow, Varanasi, Prayagraj, and Ghaziabad, cautioning of high health risks due to extreme heat.
Day temperatures have surged to 41°C in several areas, with conditions expected to worsen over the next 48 hours. Humidity levels nearing 60 per cent are compounding the heat stress, significantly increasing the risk of heat-related illnesses, especially heatstroke. Delhi is also in the grip of scorching conditions. Between May 16 and 18, the national capital is forecast to experience maximum temperatures touching 41°C, with minimums around 26°C. Adding to the crisis, air quality in Delhi and surrounding cities has plummeted to alarming levels. According to the Central Pollution Control Board (CPCB), AQI readings in areas such as Anand Vihar, Alipur, Dwarka, and Mundka have crossed 300, categorising them as “very poor”. Parts of Ghaziabad and Noida, including Loni and Sector 62, have breached the “severe” AQI threshold.
Medical professionals are warning of serious health implications. “The combination of extreme heat and high pollution is particularly dangerous for the elderly and people with heart or respiratory conditions,” said a senior physician from Delhi’s Safdarjung Hospital. Health authorities are advising residents to stay indoors during peak heat hours, remain hydrated, and use protective masks when outdoors.
There may be some reprieve ahead. The IMD has predicted light rainfall over parts of North India starting May 19, which could slightly ease current conditions. Until then, authorities urge the public to take all necessary precautions.
