September- The wettest month of the driest regions?

Rayalseema and North Interior Karnataka are the driest regions of India apart from West Rajasthan. These regions are known for their intense heat(though with exceptions lik Hubli,Belgaum,Arogyavaram etc) and rocky & dusty atmosphere.

1.Rayalseema

Bellary is included as part of Rayalseema as it belongs historically and geographically  to Rayalseema. We see that September is the wettest month of this region barring Arogyavaram which does not fit into the geography of Rayalseema. Rather it would belong to the neighbouring South Interior Karnataka which has October as its wettest month.


2. North Interior Karnataka

Belgaum is not in a proper rain shadow area. Some rain clouds do manage to peep in. Its rainiest month is July with 306mm. Bidar is almost located in the Vidharbha region which enjoys good SWM due to land based low pressures and various other factors and hence its rainiest month too is July. Other than Belgaum and Bidar, all other stations clearly have September as their rainiest month.


Hence, September is very clearly the wettest month of these two meteorological sub divisions.
