Peenya, Hennur among pockets emerging as heat islands; GBA plans cooling measures

While Bengaluru is not classified as a heatwave-prone city, pockets in it — such as Peenya, Nagawara, Hennur, and HBR Layout — are emerging as “urban heat islands”, with temperatures up to 4 degrees Celsius higher than other parts of the city, according to a baseline study.

Urban heat islands occur when dense construction, asphalt roads, and reduced greenery trap heat during the day and release it at night, making these areas hotter than their surroundings.
