Bengaluru Weather

On the other hand, Bengaluru has witnessed overnight showers, disrupting early-morning festive shopping across major areas. Many residents were seen carrying umbrellas as they made their way through waterlogged roads, particularly around KR Market, where shoppers continued with Diwali preparations despite the rain.

Areas such as Majestic, K.G. Road, K.R. Market, Town Hall, Corporation Circle, Shanthinagar, Vidhana Soudha, Shivajinagar, Basavanagudi, Jayanagar, Thyagarajanagar, Hanumanthanagar, Srinagar, Vijayanagar, Mysore Road, Magadi Road, Rajajinagar, Malleshwaram, Yeshwantpur, Peenya, Jalahalli, Dasarahalli, Shivananda Circle, Mekhri Circle, Hebbal, Yelahanka, and K.R. Puram have all reported moderate to heavy rain.

The IMD has issued an Orange Alert for South Interior and Coastal Karnataka, forecasting extremely heavy rainfall till Thursday. The alert comes in the wake of a cyclone warning for Tamil Nadu's coastal belt due to the formation of an upper air cyclonic circulation over the South Bay of Bengal.

Details of the maximum rainfall (mm) recorded in the first 50 rain gauging stations applicable across the state from 08.30 AM on 21.10.2025 to 08.00 AM on 22.10.2025.

According to the IMD, the system is likely to move west-northwestward and intensify into a depression over the southwest and adjoining west-central Bay of Bengal, close to the north Tamil Nadu-Puducherry-Karaikal and south Andhra Pradesh coasts by Wednesday afternoon.

Experts say that the increased rainfall activity is due to the interaction between the retreating Southwest Monsoon and the early onset of the Northeast Monsoon, which began on October 16 - four days ahead of its usual schedule.

Meanwhile, light to moderate showers are expected across Ballari, Chitradurga, Davanagere, and Vijayanagara districts. Temperatures are likely to stay between 20°C and 30°C, offering cooler weather conditions across southern Karnataka.

The IMD has urged residents to stay alert, avoid low-lying and waterlogged areas, and monitor official weather updates closely as rainfall is expected to continue throughout the week.
