The Tale of Two Monsoons
October's weather is defined by two major phenomena: the retreat of the southwest monsoon and the arrival of the northeast monsoon. By October 3, the southwest monsoon had already withdrawn from large parts of north and central India, including Mumbai,
which saw its earliest retreat in over two decades. This withdrawal ushers in dry, sunny weather, making it an ideal time to visit states like Rajasthan, Gujarat, and Madhya Pradesh. However, as one monsoon leaves, another arrives. The northeast monsoon, which primarily affects southern India, is expected to set in around the middle of the month. This means while much of the country is drying out, the south is just getting started with its main rainy season.
Southern India: Expect Showers
If your travel plans include the southern peninsula, a raincoat is essential. The India Meteorological Department (IMD) has forecast normal rainfall for the region as a whole from October to December. States like Tamil Nadu, Kerala, and coastal Andhra Pradesh are particularly affected by the northeast monsoon. Tamil Nadu receives nearly half of its annual rainfall during this period. Heavy rainfall is expected over Kerala, South Interior Karnataka and Tamil Nadu in the first week of October. Forecasts indicate that the northeast monsoon is likely to commence around October 15, bringing sustained showers to the region. While this makes the landscape exceptionally lush and green, it can disrupt sightseeing and beach plans.
Coastal Alert: A Cyclone Watch
A significant factor for October travel this year is the forecast for an active post-monsoon cyclone season. Researchers at the Indian Space Research Organisation (ISRO) have warned that up to three tropical cyclones could form in the North Indian Ocean (which includes the Bay of Bengal and the Arabian Sea) between October and December. The overall intensity of this cyclone season could be significantly higher than the long-term average. While these seasonal forecasts don't predict exact landfall locations or dates, they signal a heightened risk for coastal regions in states like Odisha, West Bengal, Andhra Pradesh, and Gujarat. Travellers planning trips to these coastal areas should stay updated with the latest IMD bulletins, as a cyclonic system can bring widespread heavy rain and strong winds, causing significant disruption.
North and Central India: Mostly Clear Skies
For most of North and Central India, October brings a welcome relief from the monsoon. With the southwest monsoon having withdrawn from regions like Punjab, Haryana, Gujarat, and Madhya Pradesh, travellers can expect largely dry and pleasant weather. This marks the beginning of the peak tourist season for popular destinations like Rajasthan and the Golden Triangle (Delhi, Agra, Jaipur). However, a brief wet spell is expected over parts of north India, including Punjab and Haryana, between October 6 and 9 due to a Western Disturbance. Similarly, isolated showers may occur in Bihar and Jharkhand from October 5. These are generally short-lived and unlikely to cause major travel disruptions.
The Northeast: Lingering Showers
In the northeastern states, the monsoon's retreat is often a slower, more gradual process. Scattered rainfall is expected to continue over states like Arunachal Pradesh, Assam, Meghalaya, and Nagaland through the first week of October. While the heavy, continuous downpours of the peak monsoon are over, travellers should still be prepared for intermittent showers, especially during the early part of the month. The weather generally improves as the month progresses, revealing lush landscapes and gushing waterfalls, making it a scenic time to visit for those who don't mind a bit of rain.
