Weather report October heat’ in north India : Induced cyclonic circulation will start producing thunder clouds in the plains starting from 14 October until 16 October. Scattered light to moderate rains, thunderstorms, and hailstorms will occur in parts of Punjab, Rajasthan, Haryana, Delhi NCR, and Uttar Pradesh
Last week, the southwest monsoon bid farewell to approximately 50% of India. Prominent cities such as Mumbai, Pune, Delhi NCR, Ahmedabad, Jaipur, Bhopal, Lucknow, and Chandigarh were among the areas where the monsoon withdrawal was officially declared by October 8, 2023.
This season was quite exceptional in its own right. It commenced with a cloudburst, and Himachal Pradesh and Uttarakhand experienced record-breaking rainfall, leading to flash floods. The western Himalayas bore witness to one of the most significant disasters of this century. Towards the end of the season, a low-pressure system lingered over Sub-Himalayan West Bengal, causing widespread destruction in Sikkim, parts of Bengal, and Bihar. Intense rainfall, along with cloudburst conditions, triggered flash floods and landslides in various parts of Sikkim, resulting in extensive damage to life and property between October 3 and October 6.
On October 3, within a span of 24 hours, Barisha in Paschim Medinipur recorded a staggering 522.0 mm of rainfall, which is approximately 80% of Delhi’s entire seasonal rainfall in a single day. Following Barisha, Sabang reported 438.5 mm, Amgachia 440.8 mm, and Panskura 242.3 mm of rainfall on the same day.

Western Disturbances Set to Tackle October Heat in Northern India
As temperatures in the western Himalayas continue to climb to unprecedented levels, the northern plains are sweltering under the scorching sun, with daytime maximum temperatures ranging from 35°C to 39°C. This trend is expected to persist for the next few days, particularly at the week’s outset, gradually subsiding starting from Thursday.
The arrival of the first active western disturbance of the autumn is eagerly anticipated, slated for October 14. Concurrently, a cyclonic circulation is predicted to develop over Punjab. The convergence of these atmospheric phenomena is poised to usher in an early bout of heavy snowfall across the higher reaches of Kashmir, Ladakh, Himachal Pradesh, and Uttarakhand, extending from October 14 to 16. Simultaneously, lower elevation hills can expect bouts of rain, hailstorms, and thunderstorms.
(An upcoming shift in jet streams and the development of circulation at lower wind levels around October 14 are indicative of an active western disturbance.)
The induced cyclonic circulation is projected to instigate the formation of thunderclouds in the plains, commencing on October 14 and continuing through October 16. During this period, scattered instances of light to moderate rainfall, along with thunderstorms and hailstorms, are expected in parts of Punjab, Rajasthan, Haryana, Delhi NCR, and Uttar Pradesh. While this spell of rain may impact the standing kharif crop, it should also serve to mitigate the rising pollution levels, which typically peak from mid-October onwards.
Following this weather activity, temperatures across the plains are anticipated to recede, with minimum temperatures falling below 15°C and maximum temperatures dipping under 30°C. This temperature range heralds the onset of the early autumn season in northern India.
