To understand New Delhi climate, one should get acquainted with its geographical location. Like the other parts of India, New Delhi is located in the Gangetic Plains, sitting in a dry, flat land with no other notable geographical feature other than the Yamuna River that flows from the eastern part of the city. The scorching hot drought of the Rajasthan dessert and the cool winds from the Himalayas then greatly affect the expectedly bad weather in New Delhi.
New Delhi experiences humid, sub-tropical monsoon-influenced climate. Unlike in other sub-tropical climates, India’s version of a humid climate is remarkably different from other cities such as Brisbane and Sao Pablo. The presence of dust storms in New Delhi alone makes weather in New Delhi quite an uncomfortable to some travelers.
Winters in New Delhi are dry with prolonged hot weather all throughout. Dry weather starts around November, with average temperature ranging from 12 to 13 degrees Celsius. Generally mild because of its close proximity to the Himalayas, New Delhi’s winter peak can be felt around January with cold waves and heavy fog. By December, it is dangerous to drive to, from and around New Delhi because of the fog that consequently reduces visibility and causes disruptions on road, air and railway traffic. Flights are commonly cancelled because of visibility issues brought about by the thick fog. The lowest recorded temperature drop for New Delhi during winter was at -0.6 degrees Celsius. Winter ends around February, hailing the start of a short spring season right before the onslaught of the summer season.

There are moments of dry spells with temperatures rising to 32 degrees Celsius but rainy days are usually around 25 degrees Celsius. Monsoons can continue on until late October with average temperatures ranging from 21 to 29 degrees Celsius. By November however, the New Delhi climate will start to cool just in time for most of the major festivals to begin.
Visitors who would like to take part in India’s rich cultural festivals will see October to November as the best time months to go to New Delhi.
