Kolkata's Warm Spell: When Will the Chill Return?
31 Jan
Summary
- Minimum temperature in Kolkata rose above 17°C after seven weeks.
- Western disturbances are disrupting north-westerly winds, causing temperature rise.
- A return of cooler weather is expected in the second week of February.
After more than seven weeks, Kolkata's minimum temperature has surpassed 17°C, reaching 17.9°C, which is 3.2 degrees above normal. This gradual increase signals warmer and more humid days approaching for the city.
The Alipore Met office attributes this temperature surge to successive western disturbances impacting northern India. These systems are interfering with the flow of north-westerly winds that typically bring cooler air to Kolkata. Meteorologists anticipate at least three such disturbances passing through northern regions until February 5th.
Historically, the city last recorded a minimum temperature in the 17°C range on December 5th. Following that, temperatures dropped significantly, leading to Kolkata's chilliest New Year's Eve in eight years when the mercury hit 11°C on December 31st. Earlier in January, the lowest temperature recorded was 10.2°C on January 6th.
Looking ahead, the minimum temperature is expected to remain between 16°C and 17°C, with maximums between 26°C and 28°C over the next few days. While a slight dip might occur by Saturday, no substantial change is anticipated for the next seven days. However, a return of cooler weather is predicted for the second week of February, once the influence of western disturbances wanes.
