For a city that prides itself on breezy evenings and year-round “sweater weather,” Bengaluru is facing a bit of an identity crisis. The IMD has predicted a steady rise in temperatures this week, with highs already in the mid-30s and expected to climb to 38°C — well above the city’s usual April average.What’s driving the heat?More concrete, less green: Rapid construction has replaced trees and lakes, causing the city to absorb and retain more heat.Delayed rains: Pre-monsoon showers, which typically offer relief, have been weak or delayed this year.Hotter surroundings: Rising temperatures across south India are pushing Bengaluru’s mercury higher.Warmer nights: The city is no longer cooling down as it once did, making the heat feel relentless.Will water stress follow?Bengaluru may not be facing an immediate, city-wide water crisis, but warning signs are hard to ignore. A study by the Indian Institute of Science has identified at least 65 wards as water-stressed this summer, driven by falling groundwater levels and infrastructure gaps.The city already faces a daily shortfall of around 500 million litres (MLD), leading to heavy dependence on borewells and water tankers. That strain is becoming visible: nearly half of Bengaluru’s borewells — about 7,000 — have run dry, particularly in peripheral areas. Adding to concerns, the IMD has forecast a below-normal monsoon, which could further affect reservoir levels and groundwater recharge. While central parts of the city may manage, several neighbourhoods could see intermittent supply, increased tanker reliance, and heightened water stress as summer peaks.A spike in cooling demandIndia is seeing a 25–30% surge in AC and cooling appliance salesDemand this year is 25–30% higher than last yearSome brands report 30–35% growth in AC salesGastro cases rise by 20%Gastroenterologists in Bengaluru are reporting an increase in cases of vomiting and diarrhoea this summer. Dr Tejaswini Dande recently highlighted that the season often triggers gut-related issues and shared simple precautions:Drink boiled or properly filtered waterAvoid cut fruits and street-side juicesEat fresh, hot foodDon’t store cooked food for long in the heatWash hands before eatingBe cautious with outside food during peak heatRising April temperaturesApril 16 readings over the years:2023: 34–35°C2024: 36–37°C2025: 32–34°C2026: 35–37°CSource: WeatherAPI, WeatherSparks
