Bengaluru: Persistent pre-monsoon rainfall over the past week led to an unusual phenomenon on Tuesday: Bengaluru city's maximum temperature plummeted by a staggering 8.8°C.
While the maximum temperature was just 24.4°C, the minimum temperature remained normal at 21.7°C.
This resulted in a diurnal temperature variation — difference between maximum and minimum temperatures — of only 2.7°C, far below the typical range of 5°C or more. This narrow gap made the day nearly as cool as the night, with many parts of the city seeing little to no sunlight.
N Puviarasan, Scientist 'F' and Head of the Meteorological Centre at the India Meteorological Department (IMD) in Bengaluru, attributed the low diurnal temperature variation to cloudy skies and persistent rainfall. According to him, the situation is expected to continue until Wednesday before changing on Thursday as rains recede and skies clear up.
From Wednesday onwards, the maximum temperature will rise to 28°C while the minimum will fall to 19°C, according to the IMD.
