Delhi is currently enduring a severe heatwave, with official air temperatures climbing above 40C. The extreme heat is further exacerbated by dangerously high surface temperatures. A thermal camera deployed in the city revealed that surfaces such as roads and concrete are reaching temperatures as high as 64C. This indicates that the ground itself is significantly hotter than the ambient air temperature. These elevated surface temperatures present serious health risks to the population of Delhi. Individuals working outdoors are especially vulnerable to heat-related illnesses due to prolonged exposure to these extreme conditions. The disparity between air and surface temperatures highlights the intensity of the current heat event and the potential for severe health consequences.
