October and November are the transition months for winter to step in. This is evident from the fact that two back to back Western Disturbances, a common feature during winters - have affected the weather of North India in the past 5 to 6 days. The hills have recorded good rain and snow during this period, while the plains have observed first winter rain.
Marginal drop in day and night temperatures are also being observed. The foothills of Punjab and Haryana in particular have seen a good drop in night temperatures. The national capital Delhi is also experiencing a drop of 2 to 3 degrees in the minimums. The day temperature are warm but comfortable.
For instance the Safdarjung Observatory in Delhi recorded 20.3°C as the minimum temperature on October 26, which dropped to settle at 18.5°C on October 27. It dropped further to settle at 17.5°C on the morning of October 28.
Amritsar in Punjab has seen a steep drop in minimums. According to the data available with Skymet, the city recorded 12.2°C as the minimum on the morning of October 28.
In the coming days –two week time – these minimums will drop further while the day temperatures will be comfortably warm. Western Disturbances will also become more frequent and affect the region in terms of snow and rain. The WDs will bring more variation to the temperature profile of the region.
