The Indian Meteorological Department (IMD) is facing scrutiny following a recent incident involving an unusual temperature reading in Delhi's Mungeshpur area. The IMD issued a clarification regarding the reported temperature of 52.9 degrees Celsius, suggesting it may stem from a sensor error at the automatic weather station or local factors influencing the reading.

Is the IMD's sensor reading not foolproof?

This revelation has raised doubts about the reliability of IMD's weather sensor readings, prompting concerns about the effectiveness of its monitoring systems. The IMD assures the public it is actively investigating the data and sensors to verify the temperature anomaly's accuracy. Additionally, it notes that the Mungeshpur temperature stands out as an outlier compared to neighboring stations.

In response, the IMD emphasizes the importance of data from its five major stations in Safdarjung, Palam, Ayanagar, Ridge, and Lodi Road, known as climate stations. These stations offer consistent observations over time, aiding in understanding long-term weather patterns and extremes. The IMD directs that data from these established stations should be prioritized for analyzing temperature trends and extremes.


The IMD plays a crucial role in providing weather forecasts and warnings across India, relying on an extensive network of strategically placed weather sensors. However, recent discrepancies in forecasts have raised questions about the accuracy of sensor data and its implications for forecasting reliability.

Experts highlight potential issues such as sensor malfunction or calibration errors, which could lead to inaccurate forecasts. Geographical diversity and climatic complexity further challenge maintaining a comprehensive and accurate monitoring system, especially in remote areas with limited sensor coverage.


The IMD reaffirms its commitment to maintaining accuracy and reliability in weather forecasting. It conducts regular quality control checks and calibrations on sensors to minimize errors and enhance data integrity. Efforts are underway to improve sensor network coverage and capabilities.
