Delhi witnessed its hottest day of the year on April 15, 2023, with temperatures reaching 39.2 degrees Celsius at the Safdarjung weather station, surpassing the previous day's 38.2 degrees Celsius. North Delhi recorded the highest temperature at 40.7 degrees Celsius, while other areas like Lodhi Road and Ayanagar reported highs of 39 degrees Celsius. Meteorologists attribute the rising temperatures to clear skies allowing for prolonged sunshine. The India Meteorological Department (IMD) forecasts that temperatures could reach 40-42 degrees Celsius from Friday through Sunday but has ruled out any heatwave conditions for at least the next week. Heatwaves in Delhi typically occur between April and early June, with last year seeing 11 heatwave days in April alone. The IMD advises the public, especially vulnerable groups like infants and the elderly, to avoid heat exposure and stay hydrated. Additionally, Delhi's air quality has worsened, with an Air Quality Index (AQI) of 204, indicating 'poor' air quality. The IMD has projected fluctuations in AQI levels over the coming days, with potential for 'moderate' air quality on Thursday and Friday.
