Statement on climate of India during 2022
In 2022, the annual mean land surface air temperature in India was 0.510C above the long-term average (1981-2010 period). This made the year the fifth warmest on record since nationwide records began in 1901. Despite this, it was lower than the highest warming observed over India during 2016, which had an anomaly of 0.710C, but higher than the previous year, 2021, which had an anomaly of 0.440C.
The all-India mean temperatures during the winter season (January to February) were normal, with an anomaly of -0.04°C. However, during other seasons, the temperatures were above normal. The pre-monsoon season (March to May) had an anomaly of ±1.06°C, the monsoon season (June to September) had an anomaly of +0.36°C and the post-monsoon season (October to December) had an anomaly of +0.52°C.
Global mean temperature in 2022 is currently estimated to be 1.15 ± 0.13 °C above the preindustrial (1850-1900) average. This is likely to make the past eight years (2015-2022) the warmest on record. Despite La Niña conditions keeping global temperature low for the second consecutive year, 2022 is still most likely to be the 5th or 6th warmest year on record.

During the winter season, the rainfall was 147% of its LPA, pre-monsoon season rainfall was 99% of its LPA, the southwest monsoon season had rainfall 106 % of its LPA, and the post-monsoon season had rainfall 119% of its LPA.
