Bengaluru, a city known for its pleasant, moderate climate, is experiencing an unexpected surge in temperatures, surpassing even Delhi’s daytime warmth. On February 17, 2025, Bengaluru recorded 35.9°C, marking its hottest day of the season so far, while Delhi remained much cooler at 27°C. According to the India Meteorological Department (IMD), the city’s early summer onset signals a shift in its weather patterns.

Bengaluru is witnessing a rapid rise in temperatures, making it one of the hottest places in Karnataka, alongside regions like Raichur and Kalaburagi. Typically, summer in Bengaluru begins in early March, but this year, heat waves have arrived by mid-February.
February 2025 is already 2.7°C hotter than February 2024, according to IMD statistics, demonstrating a pronounced change in the climate. Several reasons are contributing to this warming trend, including:
Absence of Northern Winds: These winds generally help cool down Bengaluru, but their lack has contributed to rising temperatures.

Despite scorching daytime temperatures, Bengaluru’s nights remain relatively cool, hovering around 17°C. However, the city’s persistent trend of overtaking Delhi’s daytime warmth has been observed for the past two years.
IMD’s forecast suggests that Bengaluru’s temperature spikes may continue, solidifying the trend of an early summer onset for the city.

Bengaluru is not immediately in danger from the heatwave, which will mostly impact northern and coastal Karnataka. However, the ongoing warming raises worries about rising energy use, water scarcity, and heat-related ailments.
