Best Time to Visit New Delhi
The best time to visit New Delhi is February. You get crisp air, sunny afternoons, and temperatures ranging from 11°C to 24°C. The heavy winter smog typically clears by early February, and the scorching summer heat hasn’t arrived yet. It is the peak season for outdoor sightseeing and garden walks. While prices are higher than in the summer, the manageable crowds and perfect walking weather justify the cost. If you want the best balance of air quality, comfortable temperatures, and local events, book your trip for the second month of the year.
Month by month
January
January is cold and atmospheric. Temperatures fluctuate between 8°C and 21°C, but nighttime lows can drop to 4°C. Expect heavy morning fog that can delay flights and trains. This is peak tourist season, so hotel prices are at their highest. Air quality is often poor due to winter inversion. You can witness the Republic Day Parade on January 26, a massive display of military power and cultural floats along Kartavya Path.
February
February offers the best weather in New Delhi. Temperatures range from 11°C to 24°C. The sky is usually clear and blue, making it the best time for photography at monuments like Humayun’s Tomb. Crowds are consistent but manageable. Prices remain high, but the sheer comfort of the outdoors makes it worth the premium. Visit the Mughal Gardens at Rashtrapati Bhavan, which usually opens to the public only during this month.
March
March marks the transition to spring. Temperatures rise to between 16°C and 30°C. Days are warm, while evenings remain cool enough for a light jacket. This is a popular month for visitors, though slightly less crowded than February. Prices start to dip toward the end of the month. You should experience Holi, the festival of colors, where the city turns into a massive street party involving powdered pigments and water.
April
April is when the heat begins. Temperatures jump to a range of 20°C to 36°C. The sun is intense by midday, so you should plan your sightseeing for early morning or late evening. Crowds thin out significantly as the heat discourages casual tourism. You can often find mid-range hotel discounts. Use this month to visit air-conditioned museums like the National Museum or the Kiran Nadar Museum of Art during the peak heat.
May
May is brutally hot. Temperatures regularly swing between 26°C and 40°C, often peaking at 45°C. Heatwaves are common, and the dry "Loo" wind makes being outdoors uncomfortable. This is the low season, meaning you can find luxury hotel deals at half their winter price. There are no crowds at major monuments. If you visit, stick to indoor activities or choose hotels with high-end pools. The International Mango Festival often starts late this month.
June
June is the peak of the Indian summer before the monsoon arrives. Expect temperatures between 28°C and 40°C, with high humidity levels starting to build. Dust storms are frequent. Prices are at their lowest point of the year, making it the cheapest time to visit New Delhi if you can handle the heat. Most locals stay indoors until sunset. Spend your afternoons in the upscale, air-conditioned malls of Saket or Vasant Kunj.
July
July brings the monsoon rains. Temperatures drop slightly to 27°C–35°C, but humidity levels soar to 70% or higher. Sudden, heavy downpours can cause localized flooding and traffic congestion. Prices remain low, and the city’s parks, like Lodhi Garden, become lush and green. This is a great time to visit the many atmospheric cafes in Shahpur Jat or Hauz Khas Village while watching the rain over the ruins.
August
August is hot and humid with frequent rain. Temperatures range from 26°C to 34°C. The humidity makes it feel hotter than the thermometer suggests. Mosquito-borne diseases can be a concern this month, so bring repellent. Prices stay low. On August 15, the city celebrates Independence Day. You will see thousands of kites flying from rooftops across Old Delhi, a tradition that defines the city’s skyline on this day.
September
September is a "shoulder" month. The rains begin to recede, but the humidity persists. Temperatures stay between 25°C and 34°C. It is an unpredictable month; you might get clear skies or sudden storms. Crowds are still thin, and hotel rates haven't hit peak levels yet. This is a good time for food tours in Chandni Chowk, as the receding rain makes the narrow alleys of Old Delhi more navigable.
October
October marks the start of the primary tourist season. Temperatures cool down significantly, ranging from 19°C to 33°C. The evening air becomes pleasant, and outdoor dining returns to popularity. Prices start to climb as international travelers arrive. This month usually features the Diwali celebrations. The city is decked in lights, and local markets like Sarojini Nagar and Lajpat Nagar are packed with shoppers looking for festive deals.
November
November is cool and comfortable, with temperatures between 13°C and 28°C. However, this month often sees a spike in air pollution following the harvest season in neighboring states. If you have respiratory issues, bring an N95 mask. Prices are high, and monuments are busy. Use this time to explore the expansive grounds of the Qutub Minar complex. The Qutub Festival, featuring Sufi music and classical dance, often takes place now.
December
December is cold and busy. Temperatures range from 9°C to 23°C. It is the most popular month for domestic and international tourists, so expect long lines at the Red Fort and Lotus Temple. Hotels are at their most expensive. The city takes on a festive vibe with Christmas decorations in malls and high-end hotels. Visit the street food stalls in Connaught Place to enjoy hot "Daulat Ki Chaat," a seasonal winter soufflé.
Cheapest time to visit New Delhi
The cheapest time to visit New Delhi is between May and June. During these months, the intense heat keeps the majority of tourists away. Luxury five-star hotels that charge $300 a night in January often drop their rates to $120–$150 to fill rooms.
You will also find significant discounts on domestic flights and private tour packages. The trade-off is the weather. With temperatures frequently exceeding 40°C, you are limited to sightseeing before 9:00 AM or after 6:00 PM. If you are on a budget and don't mind staying indoors during the day, the summer months offer the best value.
When to avoid New Delhi
You should avoid New Delhi in late May and June due to extreme heat, and in November due to air quality.
Late May and June see temperatures that can be dangerous for those not acclimated to the desert heat. Outdoor walking is nearly impossible during the day.
November is usually the worst month for smog. A combination of stubble burning in northern India and cold air trapping pollutants results in the "Great Smog of Delhi." The Air Quality Index (AQI) frequently hits "Hazardous" levels. If you have asthma or are sensitive to pollution, skip November and wait for the air to clear in late January or February.
Best time for good weather
The best time for good weather is from late October to mid-March. This window avoids the monsoons and the extreme summer heat.
- October/November: Warm days, cool nights.
- December/January: Cold, crisp weather. Requires heavy jackets.
- February/March: The "Sweet Spot." Sunny, mild, and perfect for walking.
Within this window, February is the objective winner. You get the most sunlight hours, the lowest probability of rain, and the best air quality of the winter season. The flowers are in full bloom across the city’s many British-era roundabouts and public parks.
Best time for fewer crowds
To avoid crowds while still having tolerable weather, visit in September or late March.
September is the end of the monsoon. Most tourists wait for the cooler weather of October to arrive, so you can explore the Red Fort or Humayun’s Tomb without the massive tour groups.
Late March is another effective window. Most "winter" tourists have departed as the temperature reaches 30°C, but the oppressive heat of May hasn't started. You will find shorter lines at security checkpoints and better availability at popular restaurants in areas like Khan Market or DLF CyberHub. Stick to weekdays for any major monument visit to bypass the local weekend crowds.
