On Saturday, Delhi recorded its first heatwave of the season, with the Safdarjung weather station logging a maximum temperature of 42.8°C, which is 5.1 degrees above normal. This marks the highest April temperature at Safdarjung in four years. The India Meteorological Department (IMD) confirmed that four out of five key weather stations met the criteria for a formal heatwave declaration. The Ridge station reported the highest temperature at 44.5°C, while other stations also recorded significant increases above normal. A yellow alert has been issued for Sunday, warning residents of ongoing heatwave conditions, with a possible shift towards thunderstorms beginning April 27. The IMD indicated that these heatwave conditions could persist until Sunday, with a cooling trend expected as easterly winds bring moisture to the region. Additionally, Delhi's air quality has deteriorated, with an air quality index of 243, categorized as poor. The forecast suggests a slight chance of rainfall, which could provide some relief from the heat, although temperatures are likely to remain above normal even after the heatwave conditions subside.
