The autumn or post-monsoon season lasts from October to November in India and is largely dry except for pockets of the east.
In the Northwestern India region, virtually cloudless conditions prevail in October and November. In India’s second city Mumbai, capital of Maharashtra, the autumn temperature ranges between 20-34 °C, with hardly any rain. It’s a wonderful time to visit the northwestern state of Rajasthan, whether the jewel-shops of Jaipur, the fairytale castles of Udaipur or the holy lakes of Pushkar. Temperatures averaging 15 to 32 °C (59-90 °F) in this desert region in autumn. Pushkar camel fair occurs late October to early November and is one of the largest camel, horse and cattle fairs in the world, though you are not obliged to buy!
The South is relatively dry over this period with the exception of some of the eastern coastal states such as Tamil Nadu, which despite its location on the country’s south eastern tip still feels the autumnal northeast monsoon. Temperatures in the state average 24-32 °C (75-90 °F) with rainfall of around 300 mm per day. Compare this with Goa on the Malabar Coast in the west, which has similar temperatures but 120 mm of rain in October and only 30 mm by November, the vast majority of days dry. One of the most spectacular and unusual attractions at this time is the 10-day Dasara festival held in the city of Mysore in Karnataka state, typically held early October, though it varies slightly. A Hindu festival of huge pomp and ceremony, it celebrates the goddess Chamundeshwari slaying the demon Mahishasura, symbolizing the triumph of good over evil. Mysore Palace is lit up each day with nearly 100,000 light bulbs, and processions of elephants amble through the streets carrying Hindu icons.
