According to India Meteorological Department (IMD), the northerly and north-easterly winds sweeping across the state have led to sudden fall in minimum temperatures in Bengaluru and across the state.

Based on the IMD report, many districts in north interior Karnataka witnessed minimum temperatures below 10-degree Celsius. In Bidar, the temperature plummeted to 7.6 degrees Celsius, Dharwad 14 degrees Celsius, Haveri and Raichur 13 degrees Celsius.

IMD Bengaluru Director GS Patil said that the drop in temperature was steep in the northern interior parts of the state compared to Bengaluru.

The second factor contributing to the cold conditions, Patil said, was the lack of clouds that trap the heat and keep the atmosphere warm.

The IMD has already alerted that the coming winter is expected to be colder than usual due to the prevailing La Nina conditions in the Pacific Ocean, during which winds blow stronger bringing the cold wave.
