Bengaluru Records Hottest February in Two Decades, Climate Concerns Rise
Bengaluru is experiencing an unprecedented shift in climate as the city recorded its hottest February day in 20 years, with temperatures soaring to 35.9°C on February 17, 2025. This extreme weather matches the city’s highest-ever February temperature recorded on the same date in 2005, signalling a significant departure from Bengaluru’s traditionally moderate climate. The India Meteorological Department (IMD) has forecasted that temperatures will continue to rise, bringing an early onset of summer. More strikingly, Bengaluru outpaced Delhi in terms of heat, with the national capital recording a comparatively lower temperature of 27°C on the same day. This reversal in expected weather patterns underscores the increasing unpredictability of climate trends in India.
Civic Implications: Rising Heat and Water Scarcity
The spike in Bengaluru’s temperature is not just a meteorological anomaly; it is a cause for civic concern, particularly regarding water availability. As temperatures climb ahead of summer, groundwater levels in many parts of Bengaluru are already showing signs of depletion. In response, the Bangalore Water Supply and Sewerage Board (BWSSB) has imposed strict water conservation measures, banning the use of potable water for non-drinking purposes. Violators will face a ₹5,000 fine, underscoring the urgency of the situation. With rainfall patterns becoming increasingly erratic due to climate change, experts warn that Bengaluru could face a severe water crisis if consumption is not regulated effectively. Residents have been urged to conserve water, highlighting the wider civic challenge of balancing urban expansion with resource sustainability.
Sustainability Perspective: Climate Change at Bengaluru’s Doorstep
The recent temperature surge raises concerns about Bengaluru’s preparedness to handle extreme climate shifts. Traditionally known for its pleasant weather, the city is now experiencing sustained warming trends, with temperatures rising by 2.7°C over the past year. The heatwave is a clear indicator of climate change intensifying in South India, challenging the long-held perception that North India bears the brunt of extreme weather. Rapid urbanisation, loss of green cover, and unchecked construction have contributed to the urban heat island effect, trapping heat and making the city warmer than ever before. With global climate commitments in place, Bengaluru must accelerate its efforts towards sustainable urban planning, integrating green infrastructure and climate-resilient strategies to mitigate further temperature surges.
Urban Response: The Need for Long-Term Climate Adaptation
As the city braces for an even hotter summer, experts are urging local authorities to prioritise climate resilience. Measures such as increasing tree cover, promoting rainwater harvesting, and expanding cooling infrastructure can help counteract the rising urban heat. The IMD forecasts clear skies with rising temperatures in the coming weeks, further reinforcing the need for proactive climate action. Bengaluru, once celebrated for its cool and comfortable climate, is now at a critical juncture, where unchecked urban expansion and environmental neglect could irreversibly alter its climate profile. The current crisis serves as a wake-up call for policymakers and citizens alike, demanding immediate interventions to build a more sustainable and climate-resilient future.
