Raj saw 6th highest, 2nd most intense rain in 2025 since 1901
New Delhi, Aug. 26 -- Rajasthan this year has received its sixth highest and second most intense rainfall since 1901, according to the analysis of the gridded data of the India Meteorological Department (IMD), the only official data source for tracking long-term rain trends in India.
This is the third year in a row that Rajasthan has witnessed heavy rainfall with 2025 ranking sixth and 2024 fifth in the overall rainfall received by the state till August 24. At least 91 people have died in rain-related incidents in the western state between June 1 and August 24, according to the state disaster management authority.
Till August 24 from June 1, when the monsoon officially starts, Rajasthan has received 487.6 mm rain and this is the sixth highest since 1901 - the first year for which IMD has published gridded data - and slightly less than the 493 mm rain the state received in the same period last year (ranked 5th highest since 1901).
The rain the state has received this year is also 47.3% more than the 1971-2020 average, which IMD currently considers as the Long Period Average (LPA) for tracking performance of rain.
To be sure, while the state's overall rain this monsoon is ranked only sixth highest, intense rain is ranked higher. Of the 487.6 mm rain the state has received this monsoon, 227.5 mm rain was of intensity "rather heavy" or higher.
IMD classifies over 35.5 mm rainfall at a place in 24 hours as "rather heavy". The 227.5 mm of intense rain that Rajasthan has received this monsoon is the second highest for the state for the June 1-August 24 period since 1901.
The only monsoon when intense rain was higher than the current monsoon was in 1944, when the state received 235.6 mm rain of intensity "rather heavy" or higher up to August 24. The intense rain in Rajasthan this year is 75% more than the LPA for such rain, as per IMD data. In 1944, Rajasthan had received 511.63 mm of rainfall, fourth highest ever.
Another thing to keep in mind while reading the state's overall rain performance this monsoon is that most of the seasonal surplus is so far driven by the large departure from LPA in June and July. However, some places may have suffered in August, too. While overall rain in August has a 12% deficit compared to the LPA, intense rain has a 5% surplus even in August....
