Season by season
January
Cool, sometimes cold at dawn, with frequent heavy fog; air quality can be poor.
Fog can disrupt flights and visibility, while pollution is often severe. Republic Day security measures heavily affect Kartavya Path and the central government district.
February
The year’s best balance: generally mild, dry and comfortable for long days outdoors.
It is a popular window, though it is usually easier than peak holiday periods. Air quality should still be checked, especially early in the month.
March
Warm-to-hot and generally dry, with temperatures rising quickly as the month progresses.
Afternoons can already be uncomfortable for walking. Holi changes transport, crowd and closure patterns.
April–June
Extremely hot, dry and often punishing for daytime exploration.
This is Delhi’s least comfortable sightseeing season. Heat, traffic and exposed monument sites make ambitious itineraries miserable; avoid it unless heat is not a concern.
July–September
Monsoon season: rain and humidity, but greener parks and a break from the fiercest pre-monsoon heat.
Downpours, waterlogging and humid conditions make getting around slower and messier. Outdoor plans need flexibility.
October–December
October begins more pleasantly after the monsoon; November is often comfortable for sightseeing, while December brings cooler mornings and increasing fog risk.
Air pollution can become severe from October onward and persists into winter; check the AQI and use a good mask if sensitive. Diwali brings crowds, traffic and some closures, while December can be foggy and chilly in the morning.
Events worth planning around
Republic Day · 26 January, with rehearsals and related restrictions in the days around it
The parade is significant, but central Delhi is subject to major security controls, barricades and access restrictions—especially around Kartavya Path. Book accommodation and plan transport with those disruptions in mind.
Holi · Usually March; date varies with the Hindu calendar
Memorable but disruptive: expect crowds, traffic, altered opening patterns and a less straightforward sightseeing day. Do not schedule tightly timed monument visits or transfers around it.
Diwali · Usually October or November; date varies with the Hindu calendar
Expect festive crowds, traffic and some closures. It can also coincide with worsening seasonal air pollution, so travelers with respiratory sensitivities should be especially cautious.
Getting around
Delhi Metro
Long cross-city jumps: Connaught Place, Old Delhi, Lutyens’ Delhi and the main south-Delhi corridors. It is the default visitor transport—fast, air-conditioned and generally ₹10–60.
Use Rajiv Chowk for the Yellow/Blue interchange; Central Secretariat for Yellow/Violet; Hauz Khas for Yellow/Magenta. Buy a token or use the available Metro payment options, then walk or take a short auto from the station.
It gets very crowded at rush hour and stops being a solution late at night. Coverage thins in Chanakyapuri, where there is no central station, and monuments beyond Qutub Minar station, Mehrauli’s archaeological sites and much of Nizamuddin still need a last-mile ride.
Airport Express
The cleanest, quickest airport run between Terminal 3, Delhi Aerocity and New Delhi Railway Station—especially with luggage or during Delhi traffic.
From Terminal 3, take the Orange Line to New Delhi Metro Station; the ride is about 20–25 minutes and roughly ₹60. Change there for the Yellow Line. From Terminal 1, use the airport inter-terminal transfer to T3 rather than taking a city taxi solely to reach the train.
It is an airport link, not a comprehensive sightseeing line: Aerocity is detached from the city’s visitor districts, and most attractions require a transfer at New Delhi or a cab afterward. After Metro service ends, use a reputable app car or official prepaid taxi.
Walking
Exploring one compact sight cluster at a time: Connaught Place and Janpath, Lodhi Gardens, Kartavya Path, or Old Delhi’s lanes once you are there. Walking is also the right way to experience Jama Masjid–Chandni Chowk, with a cycle rickshaw when energy runs low.
Pair it with the Metro rather than attempting citywide walks. Go early in hot months, carry water, and leave ample time for big crossings and security checks.
Delhi is not a continuous walking city. The seemingly short distances between India Gate, Connaught Place and Old Delhi are poor walks in heat and traffic; Lutyens’ Delhi has huge blocks and wide roads. Chanakyapuri, Greater Kailash and Saket are particularly weak for casual all-day walking, while Old Delhi’s narrow lanes are exhausting and best avoided alone late at night.
Uber/Ola or official prepaid taxi
Late-night travel, airport runs after the Metro, luggage-heavy moves, families, and places with poor station-to-door access—especially Chanakyapuri, Nizamuddin, Mehrauli and many South Delhi hotels.
Book through Uber or Ola where possible; at the airport or station, use the official prepaid taxi booth if you prefer a formal option. A direct car is often more sensible than piecing together transfers with bags.
Traffic can turn a short map distance into a long ride: allow 45–90 minutes from the airport in bad conditions and do not build an ambitious itinerary around cars. Decline drivers who suggest a different hotel, shop or travel agency, particularly around New Delhi Railway Station and Paharganj.
Auto-rickshaw
Short last-mile hops from Metro stations: Hauz Khas station to the village, Qutub Minar station to the monument area, or between scattered South Delhi subdistricts such as Greater Kailash and Defence Colony.
Use an app booking if available; otherwise agree the fare before you get in if the driver will not use the meter. Keep small cash as backup and confirm the amount before setting off.
Autos are not comfortable for long cross-city runs, rain or luggage, and negotiation can be tiresome. They are a poor late-night fallback in quiet residential stretches such as Lodhi Colony, Jor Bagh and Chanakyapuri; choose an app car instead.
Cycle rickshaw
The final few congested blocks in Old Delhi, especially Chandni Chowk, Jama Masjid and market lanes where cars are more hindrance than help.
Treat it as a short-distance, daytime Old Delhi tool; settle the fare before departure and use it to conserve energy between walking stretches.
It is limited to dense local lanes, not a citywide transport option. Traffic, crowds, heat and uneven access make it unsuitable for luggage, long distances or solitary late-night exploration in Old Delhi.
Safety: Delhi’s main visitor risk is scams rather than violent crime: ignore unsolicited “helpers” at New Delhi Railway Station, use Metro or app/prepaid rides, and—especially if travelling alone at night—stick to well-lit areas and prearranged transport.
Book before you land
Parliament/Samvidhan Sadan visit or a place in the public gallery during a sitting: arrange through the official parliamentary process well ahead; security procedures and access rules can change. · A timed tour of Rashtrapati Bhavan, if it is running on your dates: book from the official channel before arrival rather than assuming walk-up access. · For ordinary sightseeing, do not panic-buy reseller “skip-the-line” packages. Red Fort, Humayun’s Tomb, Qutb Minar and most museums are normally same-day purchases; save advance planning for official tours and any special event or exhibition.
- “New Delhi” is only the planned, governmental core—Lutyens’ Delhi, Connaught Place and Chanakyapuri—not the whole megacity. Think in clusters: central/Lutyens’ Delhi, Old Delhi north of Connaught Place, and the scattered south-Delhi monument zone. Old Delhi, the Red Fort and Jama Masjid are not a short walk from India Gate in Delhi conditions.
- At New Delhi Railway Station, ignore unsolicited helpers, especially anyone claiming the station ticket office has moved or that your hotel is closed. Use IRCTC for trains and Delhi Police’s prepaid taxi booth if you need a taxi.
- Carry a small amount of cash as backup, but use cards or reputable payment apps where possible; confirm the amount before an auto-rickshaw ride and never hand over your phone to a stranger offering to “help” with payment.
- Keep passport, bank cards and most cash out of reach, with only day money accessible. Delhi’s most common visitor problem is not violent crime but touts, taxi diversions, fake travel agencies and pressure-selling.
- Women should treat late-night solo movement with more caution than they might in a comparable European capital: use app cars or a prearranged pickup, stay in well-lit public areas, and do not let a driver redirect you to a supposedly unavailable hotel.
- Free time is best spent outdoors: walk Kartavya Path from India Gate toward Rashtrapati Bhavan (viewing access can be restricted), circle Connaught Place and Central Park, or use Lodhi Gardens. The Lotus Temple and many major religious sites do not charge entry, but dress modestly and expect security and occasional access restrictions.
Worth leaving the city for
Agra: Taj Mahal and Agra FortFull day — realistically 10–14 hours door to door.
This is the one indisputable Delhi day trip: the Taj Mahal is worth sacrificing a Delhi day for, and Agra Fort gives the visit substance beyond a single photograph. Take an early train rather than gambling on the expressway; the rail journey is roughly 2–5 hours each way depending on service, versus a 3–6-hour drive. The downside is brutal: expect an early start, security queues, crowds and a very long day. Do not try to bolt Jaipur onto it.
Mathura and VrindavanFull day — allow 8–11 hours door to door, including local travel between the two towns.
Go if living Hindu pilgrimage culture interests you more than another monumental tomb or museum in Delhi. Mathura, associated with Krishna’s birth, and temple-packed Vrindavan are intense, noisy and unmistakably alive rather than curated heritage sites. They are especially rewarding around Holi and Janmashtami—but those periods also bring immense crowds, traffic and disorder. Skip it if you want a quiet, polished excursion.
Bharatpur / Keoladeo Ghana National ParkFull day — about 9–12 hours door to door.
For birders, this beats another day amid Delhi traffic and monuments: Keoladeo is a serious wetland reserve and a complete change of scene. It is most compelling in the migratory-bird season; outside it, only committed naturalists should trade Delhi time for it. Getting from Bharatpur station to the park adds friction, so this is not a casual half-day outing.
