An Overview of Delhi’s Climate
Delhi has a “humid subtropical” climate, characterized by three distinct seasons:
- Winter (October to March): Cool and pleasant.
- Summer (April to June): Hot to extremely hot and dry.
- Monsoon (July to September): Hot and humid with heavy rainfall.
Let’s break down what each month has in store.
Season 1: Winter (October to March) – The Peak Tourist Season
This is widely considered the best time to visit Delhi. The weather is at its most pleasant, making it ideal for sightseeing, outdoor cafes, and exploring historical monuments.
October & November: The Perfect Start
- Weather: The intense heat of summer has fully receded. Days are warm and sunny, while nights become increasingly cool and crisp.
- What to Expect: This period marks the beginning of the festival season, with Diwali usually falling in October or November. The air quality can start to decline post-Diwali due to firecrackers and agricultural burning.
- Packing Tips: Light layers for the day, and a light jacket or sweater for the evenings.
December & January: Peak Winter
- Weather: These are the coldest months. Daytime temperatures are pleasant (around 20°C/68°F), but nights and early mornings can be downright chilly, often dropping to 5-7°C (41-45°F). Dense fog is common, which can lead to flight and train delays.
- What to Expect: The famous Republic Day Parade on January 26th is a major highlight. Markets are decked out for Christmas and New Year.
- Packing Tips: Pack warm clothing—sweaters, jackets, scarves, and thermals for especially cold nights.
February & March: The Gentle Transition
- Weather: The harsh cold begins to fade. February is still mild, but by March, you’ll feel a significant warm-up. The days become warmer, signaling the approaching summer.
- What to Expect: This is a beautiful time as many flowers, including the iconic mustard blossoms, are in full bloom. Holi, the festival of colors, is celebrated in March.
- Packing Tips: A mix of light clothes for the day and a light jacket for the cooler evenings.
Season 2: Summer (April to June) – The Scorching Heat
Summer in Delhi is intense, with high temperatures and dry, dusty winds known as “loo.”
April: The Warm-Up
- Weather: The heat becomes pronounced. Daytime temperatures regularly cross 35°C (95°F).

- Packing Tips: Lightweight, breathable cotton clothing, a wide-brimmed hat, sunglasses, and strong sunscreen are essential.
May & June: Peak Summer Heat

Season 3: Monsoon (July to September) – The Soaking Relief
The monsoon season brings much-needed relief from the heat, but introduces its own set of challenges with high humidity and heavy downpours.
July & August: The Heart of the Monsoon
- Weather: Humidity levels rise dramatically. Delhi receives the majority of its annual rainfall during these months, often in short, intense bursts that can cause waterlogging and traffic disruptions.
- What to Expect: The city turns lush and green. While the rain cools things down, the humidity can make it feel sticky. Be prepared for sudden changes in plans due to heavy showers.

September: The Monsoon Retreats
- Weather: The rainfall begins to taper off. The weather remains humid, but temperatures start to become more moderate.
- What to Expect: This is a transitional month. The greenery is still vibrant, and the festival season begins to ramp up towards the end of the month.
