During the entire Monsoon season, South Interior Karnataka has been witnessing huge fluctuation in rainfall amounts. In June when rainfall was poor across the country the deficit in North Interior Karnataka was 52%, Coastal Karnataka 43% and South Interior Karnataka 24%, which is close to normal of +-19%. Thereafter, all the three sub-divisions recovered in July and almost became normal. South Interior Karnataka was surplus by 11% during this month.
By the third week of August, South Interior Karnataka was the only sub-division observing excess rainfall by 20%. It continued to remain excess till the 15th of September. On 7th September it was excess by 24% after which a gradual decline started. The reason for this decline was decrease in rainfall across peninsular India. For the last 4-5 days this region is observing 50% of its daily rainfall thereby, consuming the surplus amount. According to Skymet Meteorology Division in India, rainfall amounts in South Interior Karnataka may take a further dip.
Monsoon in India is almost going to conclude and there isn't hope of any sub-division being surplus this monsoon season. According to the data available with Skymet Meteorology Division in India, there were 7 sub-divisions that were surplus in 2011, when the country had experienced 102% of the Long Period Average (LPA) rainfall. In 2012, which was a year of poor monsoon rain, there was one sub-division, Andaman and Nicobar Islands that was surplus. In 2013, there were 14 surplus sub-divisions and the LPA was 106%.
