Eleven districts in Karnataka, including Bengaluru Urban, recorded deficit pre-monsoon rainfall between March 1 and May 11.
According to the district pre-monsoon pattern of the Karnataka State Monitoring Center Natural Disaster Monitoring Center (KSNDMC), during this period Bengaluru Urban (-23%), Bengaluru South (-29%), Tumakuru (-21%), Chitradurga (-44%), Vijayanagar (-24%), Kosanda Hasguanger (-24%), Kosanda Davangere (-25%) (-48%), Mysuru (-50%), Mandya (-42%) and Chamarajanagar (-39%) experienced rainfall deficit.
Rainfall is considered normal when it is between +19% and -19%, deficient when it is between -20% and -59%, heavy when it is -60% or less, excessive when it is between +20% and +59%, and very excessive when it is +60% or more.
Sixteen districts – Bengaluru Rural, Chickballapur, Kolar, Dakshina Kannada, Udupi, Chikkamagaluru, Shivamogga, Uttara Kannada, Haveri, Ballari, Koppal, Bagalkot, Belagavi, Vijayapura, Yadgir and Bidar – fell normally.
While Bidar, Raichur and Gadag received excess rainfall, Dharwad and Kalaburagi received large excess rainfall. KSNDMC data from the taluks reveals that 11 taluks received heavy rainfall deficit, 99 taluks received deficit rainfall, 72 taluks received normal rainfall, 33 taluks received excess rainfall and 21 taluks received large excess rainfall.
The summer has been intense across the state, with several districts in northern Karnataka recording maximum temperatures above 40°C on many occasions.
In Bengaluru, for example, the temperature was above 35°C for most of April and even crossed the 36°C mark on many occasions.
On Monday (May 11), the IMD forecast said that the maximum temperature will increase by 2-3°C in northern Karnataka during the next five days.
“During the next five days, there will be no major change in the maximum temperature over coastal Karnataka and south interior Karnataka,” the IMD said.
The IMD has already said that in 2026, the southwest monsoon season (June to September) rainfall over Karnataka is expected to be below normal in most parts of the state. However, some areas in Northeast and Southeast-Interior Karnataka are likely to receive normal to above normal rainfall.
