Delhi is currently under an extreme heatwave, with temperatures soaring above 46 degrees Celsius at several locations. The India Meteorological Department (IMD) has issued an orange alert effective until May 26, warning residents of persistent heatwave conditions with maximum temperatures projected between 43°C and 47°C. The Safdarjung weather station recorded a maximum of 44.5°C, while Mungeshpur reached 46.3°C and the north Delhi ridge station recorded 46.5°C. This marks the third consecutive day of extreme temperatures. Experts note that a western disturbance may bring some rainfall to the region starting May 23, potentially alleviating the heat slightly. However, the immediate forecast suggests temperatures will remain high. Additionally, a heat risk assessment indicates that over half of Delhi’s districts are at very high risk due to increasing warm nights, which hinder recovery from daytime heat stress. In terms of air quality, Delhi's air quality index (AQI) has improved to 168, classified as moderate, following the invocation of stage-1 measures by the Commission for Air Quality Management.
