Meteorologically, the state of Karnataka has three subdivisions, namely Coastal Karnataka, North Interior Karnataka, and South Interior Karnataka. The Monsoon rains are recorded the heaviest over Coastal Karnataka, second by South Interior Karnataka with a sharp decline in rains. North Interior Karnataka receives the least amount of rains.
However, so far, Monsoon has performed pretty well for the state. Karnataka as a whole has recorded a total of 458.6 mm rains so far against the state’s monthly normal of 437.7 mm of rains, making the rainfall surplus settled at 5%.
Administratively, Karnataka can be divided into 4 divisions, Belagavi, Bengaluru, Kalaburgi, and Mysuru. All the four divisions enjoy the diverse performance of Monsoon rains.
The coastal districts of the state share their boundaries with Belagavi and Mysuru divisions.
The best performing division is Mysuru that falls in the South Interior Karnataka region. So far, almost all the districts of this division have performed well except Chamrajnagar which is largely deficient by 49%, followed by Mysuru that is deficient by 48%.
Rest almost all the districts have performed well so far. Dakshin Kannada and Udupi districts have performed satisfactorily with minor rainfall deficiency of 10% and 15% respectively which is considered to be normal.
In Belagavi division, almost all the districts are rainfall deficient except Belagavi and Uttara Kannada that have performed pretty well with rainfall surplus of 39% and 2% respectively. The worst performing being Bijapur which is largely deficient by 36%.
The worst performing division is Kalaburgi which is a part of North Interior Karnataka. All the districts of this regions are rainfall deficit by a large margin. However, Kalaburgi is still in a better position with the rainfall deficiency of 13% which is normal. The worst deficiency is 56%.
Bengaluru division is in a satisfactory position with mainly two districts bearing large deficiency. Chikballapur is rainfall deficient by 43% and Kolar is 33% rain deficient.
As of now, we expect light to moderate rains to occur over the coastal districts of the state. However, this is also not likely before the second half of the week. The interior regions of the state, on the other hand, are expected to continue with light rains. Hence, it can be said that due to the major reduction in the rains over the state as a whole, the rainfall surplus of 5% may get consumed.
