Bengaluru weather returns to normal winter mode for December after a week of light rain, cloudy skies

On Monday, the maximum temperature in the city reached 29.2°C, which is two degrees above normal, while the minimum temperature was 16.1 °C, which was 0.3 degrees below normal. The lowest recorded temperature in Bengaluru on that day was 13.3°C at Yelahanka.

Over the next two days, the minimum temperature is projected to go down to 13.1 °C in some parts of the city as the winter weather sets in, resulting in a notable difference between day and night temperatures, with a nearly 15°C variation between maximum and minimum readings.

Although Bengaluru is expected to remain within the normal winter range, the minimum temperature in parts of north interior Karnataka, including Bidar and Belagavi, may drop up to five degrees, signalling the likelihood of significantly cold weather. The cold wave in Bidar in north Karnataka is likely to prevail for five days.

During the first week of December, Bengaluru recorded temperatures that were significantly below the seasonal average, along with light rain due to cyclonic storm Ditwah, off the coast of Tamil Nadu.

The maximum temperature was nearly six degrees below normal for the season of 27°C, while the minimum temperature was a bit lower than the normal of 16.4°C. The mean maximum temperature in December in Bengaluru over the last 15 years is 26.9°C, while the minimum temperature was slightly below the normal of 16.4°C.

The lowest-ever recorded minimum temperature in Bengaluru was 7.8 °C, recorded on January 13, 1884, according to IMD’s historical records. The lowest minimum temperature recorded in December in the last 15 years is 12.8°C on December 24, 2011, while the lowest-ever minimum temperature recorded in the city was 8.9°C on December 29, 1883.
