As the official Monsoon season comes to an end, I present the final Monsoon Report of the year with an almost 10% above normal performance. What a spectacular year this has been, and I have the added pleasure of preparing and posting this report from the beautiful state of Sikkim!

It's next to impossible for any metro city in India to catch up with Mumbai rains.

Nicely presented.
It was an amazing monsoon keeping in mind that at end of June the rains were 33% below normal.
Harayana missed out big time. 42% below normal is huge.

Thanks to GSB,Pradeep,Abhijeet for prompt numbers.

If we notice Tamil Nadu and South AP rayalseema regions have received only 50% of rain what GUJ/RAJ has received. Even if add unreliable NEM figures will this augment figures for TN/AP? TN / AP average is very less as of now 500mm (lets us wait for NEM) competition for India driest states/regions - how geography has changed over time?


Now we can see observe driest states and regions of India - it is no longer GUJ or RAJ but TN/AP. Main reason can be climate changes over decade - SWM is becoming stronger but NEM is becoming weaker every passing year. SWM always tends to be strong and spend more duration over MAHA,Central India,GUJ,RAJ leading to less rains in lower latitudes. Main worry is lack of rains over SI KAR - Cauvery catchments - Kodagu basin / Augumbe.

As far as northern parts are concerned they have bountiful ganges + WDs (annoying for NEM) to rescue apart from SWM.
