Bengaluru, known for its generally mild climate, is set to experience a noticeable and persistent drop in temperature this week, marking a significant shift toward a much colder winter bite. According to forecasts issued by the India Meteorological Department (IMD), the minimum temperature in the city, which has been hovering around the comfortable 16°C mark over the past few days, is projected to fall to between 12°C and 14°C over the next few days. This sharp dip is particularly noteworthy as the city's average minimum temperature for December typically sits around 16.4°C.
The Coldest December Since 2016
The anticipated minimum temperature of 12°C is expected to be the lowest reading recorded in the month of December since 2016, a year when the mercury touched that same threshold on December 11th. While the rest of North and Central India prepares for full-fledged cold wave conditions, Bengaluru's chill is driven by regional meteorological factors and will be distinctly below normal. This change means residents should expect notably crisper nights, making the early mornings particularly cold and often enveloped in the signature Bengaluru mist or fog.
Meteorological Reasons for the Sharp Decline
The significant fall in night temperatures is primarily attributed to a combination of meteorological factors influencing the South Indian weather pattern. Experts from the IMD point to several key reasons for the sudden intensification of the cold:
-
Clear Skies: The absence of cloud cover allows for more effective radiation of heat accumulated during the day back into the atmosphere, causing temperatures to drop sharply overnight.
-
Dry and Cold Northerly/Northeasterly Winds: The influx of dry and colder air mass from the northern parts of the country, which are already under the grip of winter, contributes to the overall cooling.
- Stable Air: Stable atmospheric conditions prevent the warmer air from circulating, trapping the cold air closer to the ground, especially during the late night and early morning hours.
Impact on Daily Life and Commuters
The colder weather is expected to impact daily life, especially for those commuting or working during the early morning and late night. The significant drop to 12°C will necessitate heavier winter wear than the light layers usually donned in Bengaluru. Furthermore, the forecast for dense early-morning mist and fog in isolated pockets could affect visibility, prompting the IMD to advise commuters to exercise caution on roads, especially during peak fog hours. While the maximum daytime temperature is expected to remain pleasant, hovering around 26°C to 27°C, the distinct contrast between the day and night temperatures will be keenly felt across the city. Residents are advised to take necessary precautions to stay warm and monitor local weather updates.
