South India: The Northeast Monsoon Arrives
Southern states are the most likely to experience significant rainfall in October. The India Meteorological Department (IMD) has indicated that the northeast monsoon, which brings rain primarily to this region, is expected to commence between October 15
and 21. States like Tamil Nadu, Kerala, Puducherry, coastal Andhra Pradesh, and South Interior Karnataka are forecast to receive heavy showers. For travellers, this could mean disruptions to beach plans, waterlogging in cities like Chennai, and challenging conditions for exploring backwaters in Kerala. The IMD has issued forecasts for fairly widespread rainfall and thunderstorms for Kerala and Tamil Nadu through the first week of October and beyond. While the landscapes will be exceptionally lush, be prepared for downpours and plan activities with flexibility.
Eastern India and the Andamans: Lingering Showers
Parts of Eastern India, including West Bengal, Odisha, Bihar, and Jharkhand, are also expected to see isolated to scattered rainfall during the first and second weeks of October. According to IMD forecasts, Sub-Himalayan West Bengal and Sikkim in particular could see continued rain and thunderstorms. For those planning trips to Darjeeling or Gangtok, this may result in misty conditions and the potential for travel delays. The Andaman and Nicobar Islands, another popular October destination, are in a shoulder season. While the heaviest of the monsoon has passed, intermittent showers and thunderstorms are still likely, especially in the first half of the month. Ferry services between islands can be affected by weather, so it's wise to build extra buffer days into your itinerary.
The North: A Mixed and Changing Picture
For the most part, North India is expected to remain largely dry as the southwest monsoon completes its withdrawal. This makes October an excellent time to visit states like Rajasthan, Punjab, and even the plains of Uttar Pradesh, where the weather becomes much more pleasant. However, the IMD has also forecast the possibility of isolated to scattered rainfall in Himachal Pradesh and Uttarakhand from October 5 to 10. While this is not expected to be a major deluge, those planning treks or mountain drives should be aware of potential thunderstorms and lightning, especially between October 6 and 8. Delhi is also forecast to see some light rain around October 6 to 8 after a sunny start to the month.
Central and West India: Mostly Clear Skies
The withdrawal of the southwest monsoon is well underway across Central and West India. The IMD announced the monsoon's retreat from Mumbai on October 3, earlier than its normal date. This means states like Maharashtra, Gujarat, and Madhya Pradesh are transitioning to drier, post-monsoon conditions. While most of this region will offer clear skies perfect for travel, some lingering moisture might lead to isolated showers. Hot and humid conditions are expected to prevail in coastal Maharashtra (Konkan and Goa) for the first few days of the month. By the second week, most of Central India is expected to be dry, making it ideal for visiting national parks like Kanha and Bandhavgarh, which typically reopen post-monsoon around this time.
