Bengaluru – Temperatures soared to 35°C during lunch hours on April 29, 2026, only for a powerful hailstorm to batter the city by evening.[1][2] The abrupt shift from scorching heat to ice pellets blanketing streets caught residents off guard and unleashed widespread chaos. At least 10 people lost their lives amid the storm’s fury, marking a tragic end to the city’s prolonged heatwave.[3]

Swift Onset of the Tempest

Dark clouds gathered rapidly over Bengaluru as the afternoon progressed, leading to intense thundershowers around 5 p.m. Heavy rain poured down at rates up to 80 mm at the city observatory, accompanied by gusty winds reaching 75 kmph.[2] Hailstones piled up in thick layers across central areas, transforming urban landscapes into temporary winter scenes.

The storm lasted over an hour in many spots, with the central business district bearing the brunt. Areas like Ashok Nagar and those near Kanteerava Stadium saw sidewalks and roads covered in ice, while stormwater drains overflowed almost immediately.[3] Commuters faced sudden visibility drops and flooded underpasses, stranding thousands during peak evening hours.

Heavy Toll on Lives and Infrastructure

The hailstorm claimed 10 lives in separate incidents tied to the extreme weather. A wall collapse at Bowring Hospital in Shivajinagar killed seven people, including a young girl preparing for her birthday. Two others died from electrocutions – one a 17-year-old in Shivajinagar and another on Bannerghatta Road – while a roof and wall failure in Chamarajapet took one more life. Nine individuals suffered injuries from the hospital incident.[3]

Infrastructure buckled under the onslaught. More than 100 trees fell, snapping power lines and causing outages that prompted 25,000 distress calls to the electricity board. Over 50 electric poles toppled, 17 transformers failed, and traffic ground to a halt on major roads like MG Road and JC Road due to waterlogging up to 2-3 feet deep.[3] Metro services slowed as platforms flooded, exacerbating the evening rush disruptions.

Areas Hit Hardest

• Central business district, including Kanteerava Stadium and Catholic Club, where hail blanketed grounds and cafes.
• Shivajinagar, site of the fatal wall collapse at Bowring Hospital.
• MG Road, Church Street, Indiranagar, Koramangala, and Ulsoor, plagued by flooding and fallen branches.
• Southern zones like Banashankari, BTM Layout, and Bellandur, with power cuts and vehicle breakdowns.
• Key spots such as Town Hall, KR Market, Cubbon Park, and Majestic, where winds toppled trees and debris choked drains.[4]

These locations highlighted the storm’s broad reach, shifting from districts like Mysuru before intensifying over the capital.

Science Behind the Shift

Meteorologists attributed the event to convective activity fueled by elevated heat levels. A low-level wind discontinuity and moisture convergence spurred the development of the squally system.[2] “The hailstorm is due to convective activity caused by elevated heat levels. Low-level wind discontinuity, coupled with moisture convergence, aided its development,” said N Puviarasan, Scientist ‘E’ and head of the IMD’s Bengaluru Meteorological Centre.

The India Meteorological Department issued an orange alert by 5:30 p.m., warning of moderate rain, thunderstorms, hail, and gusty winds. Pre-monsoon showers had already begun arriving in south interior Karnataka the day prior, signaling an early shift in patterns.[2]

Relief, Response, and Outlook

While the storm brought a sharp temperature plunge – the minimum dipping to 18°C, below the normal 22.5°C – it offered respite from weeks of relentless summer heat.[2] Chief Minister Siddaramaiah visited the worst-hit Shivajinagar to assess damage, deploying teams to clear debris and restore services. Electricity and civic authorities worked overnight to address outages and flooding.

Forecasters predicted more scattered hailstorms on April 30 and rain-thundershowers on May 1 afternoon or evening. Bengaluru residents now eye the skies warily, balancing gratitude for the cool-down against the lessons of nature’s unpredictability. The episode underscores the intensifying pre-monsoon volatility in the region.
