2019 was 7th Warmest since 1901

Date: 09 January 2020 Tags: Climate Change


The year 2019 that went by was the 7th warmest since record-keeping commenced in 1901. However, the rise in average temperatures over India in 2019 was the lowest since 2016.



During the year, the annual mean surface air temperature, averaged over the country, was +0.36°C above average. The average is defined as the mean temperature from 1980-2010.



  • The highest warming observed over India was during 2016 or 0.71°C above the mean. 2018, which was the 6th warmest in India, was 0.41°C, and 2017 was 0.55°C warmer, than the average.

  • According to the World Meteorological Organisation, the rise in global mean surface temperature during 2019 (January to October) was +1.10°C.

  • The main contributors to the warming this year were temperatures in the pre-monsoon (March-May) and monsoon seasons (June-September).

  • 2019 was also characterised by unusually high rainfall, which was 9% over what is normal for a year which was due to monsoon rains (June-September) being 10% over its normal, and the northeast monsoon rains being 9% over its normal.

  • During 2019, eight cyclonic storms formed over the Indian seas, with the Arabian Sea contributing five out of these eight cyclones against the normal of one per year.

  • This was a phenomenon not seen in India since 1902. This was, meteorologists said, due to a strong Indian Ocean Dipole, or an IOD, which cyclically heats the West Indian Ocean that stimulated cyclone formation over the Arabian Sea.
