Monsoon 2018 Overview: Serious Anomalies Hidden by Macro Figures

2018 becomes fifth year in a row when India’s south west monsoon has been below normal.  In the beginning of monsoon season, Indian Meteorological Department (IMD) has forecasted rains to be normal with rainfall equal to 97 percent of the long term average. However at the end of the season the overall rainfall turned out to be 91 percent, with deficit of 9 percent at national level. However, as we see in this overview, the situation as move from national to local figures, is much different, mostly much worse.

According to IMD’s State Rainfall Map (cumulative) dated 30 Sept. 2018, the country received 804.0 mm rains against 887.5 mm of normal average. Thus the south west monsoon 2018 had 9.4 percent below normal rainfall.

According to map, 8 states and Union Territory (UT) Lakshadweep have received deficit rains. Interestingly 7 of these rain deficit States/ UTs are from East and North East India. If Assam with -18 deficit is also included in the list, it may be concluded that the East and North East region suffered worst deficit of rain in 2018 monsoon season.

The map also shows that Gujarat is the only state from western India which has fell short of Normal Monsoon category. 26 States plus UTs have received normal rainfall while with 23% surplus rain, Kerala is the only state in excess rain category.
