# IMD Corrects August Rainfall Data After Initial Error

India's Meteorological Department (IMD) revised its reported rainfall data for Delhi in August after an initial incorrect figure was published. The city's cumulative rainfall still falls below the monthly average.

## Key takeaways

- The India Meteorological Department (IMD) corrected its reported August rainfall data for Delhi.
- An initial report stated Delhi had received over 234mm of rain in the first 10 days of August.
- The IMD later revised the cumulative rainfall figure to 197.2mm, confirming the earlier data was incorrect.
- This corrected figure shows Delhi is still short of its average August rainfall by approximately 36mm.
- The error was traced to an incorrect rainfall entry for August 6.

The India Meteorological Department (IMD) has corrected a significant error in its recorded rainfall data for Delhi during August. Initially, the agency reported that the city had surpassed its average rainfall for the month, but this figure was later revised.

The correction came after the IMD stated on Tuesday that Delhi had received 234.5mm of rain in the first ten days of August, exceeding the month's expected total of 233.1mm. By Tuesday, the IMD quietly updated its bulletin, reducing the cumulative rainfall figure for the month to 197.2mm.

An official from the IMD confirmed that the earlier cumulative figure was incorrect. The agency explained that an erroneous entry of 56mm for rainfall on August 6, instead of the actual 18.7mm, led to the inflated total. This specific error accounted for a discrepancy of 37.3mm. The corrected figure of 197.2mm indicates that Delhi is still approximately 36mm short of its average rainfall quota for August.

This incident follows other instances where the IMD's rain predictions or logs have been inaccurate. On Tuesday, the agency issued an orange alert predicting light to moderate rain across most of the city, with some areas expecting heavy showers. However, by late Tuesday afternoon, rainfall measurements in various parts of Delhi were minimal, with Safdarjung recording 4mm as the highest.
