According to IMD’s own analysis, the maximum temperature in India until April 28 was the fourth highest since 1901 and 1.12 degrees above normal.
The average maximum temperature in India for April was 35.83 degrees Celsius, 0.86 degrees higher than the 1981-2010 average, which is considered normal, according to the India Meteorological Department (IMD) gridded dataset. According to IMD’s own analysis, the maximum temperature until April 28 was the fourth highest since 1901 and 1.12 degrees above normal. This difference in numbers is because the gridded data set uses a slightly different list of stations and math operations. Calculating the exact April 2022 ranking is also beside the point.
The temperature since March, and especially in April, has shown what even small deviations from normal can look like. The following four charts explain why that is the case.
1. Most regions don’t need big deviation to get very hot in April
2. Even small deviations in the second half of April can lead to high temperatures
3. India has seen a very rapid warming after the 1980s…
4. …and local factors made it worse in April
