The maximum temperature over Delhi NCR varied from 45.2° to 49.1°C in different parts of the city. Mungeshpur reported 52.9°C in last week, as an outlier compared to other stations.

“It could be due to an error in the sensor or the local factor. IMD is examining the data and sensors”, says the Indian Meteorological Department.

The Indian Meteorological Department released Temperature data over Delhi based on its Automatic Weather Stations network installed since the summer season of 2022 and made operational reporting of temperature and rainfall observations for 15 new locations spread over different parts of Delhi and NCR.

According to IMD, the maximum temperature was recorded on 29th May by five departmental observatories at Safdarjung, Palam, Ayanagar, Ridge and Lodi Road as well as 15 AWS.

It rained at many places in Delhi yesterday resulting in a further fall in temperature. Heatwave conditions will reduce during the next 2–3 days due to a gradual fall in temperature in association with approaching western disturbance, rainfall thunderstorms and southwesterly wind blowing from the Arabian Sea to northwest India.

Temperature in urban areas varies from place to place due to local exposure such as proximity to water bodies, barren land, concrete and dense urban clusters, green areas etc.

IMD has five major stations regularly reporting observations for long periods and they are referred to as climate stations. The long-period data fulfilling all the exposure conditions are available from these five department observatories of IMD. Data from these five stations should be considered to find out trends and extremes.
