Bengaluru, known for its mild and moderate climate, is preparing for a colder winter than usual this year. The city has already started feeling the chill, with temperatures dipping below 20 degrees Celsius. According to the India Meteorological Department (IMD), the temperature is expected to drop even more in the coming months. This unusual cold spell is mainly due to La Nina conditions and the extra rainfall the city received during the monsoon season. Residents can expect the cold to get more intense, with the minimum temperature possibly falling as low as 12-14°C during December and January.
Bengaluru's weather is undergoing noticeable changes. One of the most striking changes is the dense fog covering the city's outskirts on recent mornings. This fog is caused by the moisture that built up on the surface level from the heavy rainfall. When the temperature drops at night, this moisture forms a thick fog, especially in areas on the outskirts of the city. The lack of cloud cover and the increase in moisture make the cold feel more intense.
Unexpected Weather Shifts in Bengaluru
Meteorologists have observed that while the nights are getting colder, the daytime temperatures are still expected to stay high, around 28-30°C. This creates a significant temperature difference between day and night, which may be hard for residents who are used to Bengaluru's normally stable climate. The contrast between hot, humid days and cold nights is due to the excess moisture in the air and the influence of weather systems over the Bay of Bengal and Arabian Sea.
Bengaluru has also received more rainfall than usual this year, exceeding its annual rainfall quota. Until September, the city had a 21% rainfall deficit, but by November 11, Bengaluru had recorded over 104cm of rain, surpassing the normal annual rainfall of 98cm. The total rainfall is expected to reach 110cm by the end of December, making it a year with more than 25% above average rainfall. The heavy rainfall in October helped reduce the initial deficit, pushing Bengaluru into the 'slightly excess rainfall' category.
Rainfall Patterns and Future Projections
The IMD has forecast light-to-moderate rainfall in the coming days. While this rain won't be too heavy, it will contribute to the cool atmosphere, making the cold feel more noticeable. This shift in weather patterns highlights how Bengaluru's climate is changing, influenced by larger meteorological events.
Bengaluru is experiencing a noticeable change in its weather as the city enters winter. Temperatures are dropping earlier than usual, and the city is dealing with bigger differences between day and night temperatures. With the IMD predicting a colder winter ahead and more rainfall expected, residents will have to adjust to the changing climate while also considering the effects of exceeding their annual rainfall quota.
