Delhi in a 45°C heatwave: an hour-by-hour two-day plan
Empty red sandstone colonnade in Delhi at dawn with heat haze over the lawns
May and June regularly push Delhi past 44°C with the dry loo wind blowing from the west, so this two-day plan puts every outdoor hour before 10am or after 6pm and gives the middle six hours to air conditioning.
The rules that make a heatwave visit survivable
Delhi's hot season runs mid-April to late June, with daily highs of 40 to 46°C, night lows that stall around 30°C, and single-digit humidity until the pre-monsoon storms arrive. The killer is not the peak number but the duration: from about 10.30am to 5.30pm the stone, sand and traffic radiate heat back at you and shade is thin at almost every monument. Dust storms roll in on some June evenings, dropping visibility and temperature within twenty minutes. Plan around a hard rule: nothing outdoors between 10.30 and 5.30, no exceptions for a monument you flew in to see.
Second rule, drink before you are thirsty. Two to three litres a person per day minimum, with oral rehydration sachets from any chemist at about ₹20 each, one in the morning and one at 4pm. Third, dress for it — loose cotton, long sleeves rather than bare arms, a hat, and closed shoes for gravel that hits 50°C. Fourth, book a hotel whose air conditioning you trust and which has a pool or at least a shaded terrace; in June the pool is not a luxury, it is the reason the afternoon is bearable.
Day one, 5.30am to 10.30am: Lodhi, Nizamuddin, Sunder Nursery
Wake at 5.15. Lodhi Garden opens at 6am, free, and the fifteenth-century Bara Gumbad and Sheesh Gumbad tombs sit among the biggest trees in central Delhi — this is the coolest ninety minutes of your day and the whole colony is out walking. At 7.30 move to Sunder Nursery, which opens at 7 and charges roughly ₹100 to ₹200, where the paved paths, water channels and shaded benches make an hour comfortable, and the café inside does breakfast from 8. Bank the shade; you will spend the afternoon indoors regardless.
By 8.45 walk through to Humayun's Tomb, entry about ₹40 for Indian nationals and ₹600 on a foreign passport. The main chamber and the arcaded plinth hold cool air until mid-morning and the new sunken site museum, opened in 2024, is fully air conditioned, which makes it a legitimate heat refuge as well as a good museum. Leave by 10.15 and take a cab, not the metro walk. One monument before ten in June is a full morning's achievement; do not try to add Qutub as well.
Day one, 11am to 5.30pm: the indoor block
Eat early, at 11.30, then choose one long air-conditioned stop. The National Museum on Janpath, closed Mondays, entry roughly ₹20 and ₹650, holds the Harappan dancing girl, the Buddhist relics gallery and a good miniature painting collection; two hours goes quickly. The Crafts Museum on Bhairon Marg is the alternative with live craft demonstrations, and the National Gallery of Modern Art at Jaipur House is the quietest of the three. All are ten minutes apart by cab in the Lutyens grid, so you can chain two if the day is going well.
At 2.30pm go back to the hotel and swim, or sit in a mall. This feels like wasted holiday and it is not: heat exhaustion on day one costs you day two. Select Citywalk in Saket, DLF Promenade in Vasant Kunj and the Aerocity plaza all have cinemas showing English-language releases with an interval, tickets ₹250 to ₹600. If you would rather stay cultural, the Kiran Nadar Museum of Art in Saket is free, cold and rarely busy. Emerge at 5.30 with a full water bottle.
Day one, 6pm to 10pm: markets, water and kulfi
Delhi comes back to life at dusk in June. Start at Gurudwara Bangla Sahib off Ashoka Road, open all hours, free, where the marble is finally walkable and the sarovar tank cools the whole courtyard; the langar kitchen serves anybody. From 7.15, Connaught Place's inner circle colonnades are shaded and the Agrasen ki Baoli stepwell on Hailey Road, free and open till around 6pm, is worth the earlier slot if you can make it. Dilli Haat at INA, entry about ₹30, runs until 10pm with craft stalls and state food counters.
Eat late and cold. Roshan di Kulfi in Karol Bagh does a rabri-faluda kulfi for around ₹150; Kuremal Mohan Lal in Sitaram Bazar in the old city stuffs whole mangoes with kulfi in season, which is exactly the season you are visiting. Drink shikanji, aam panna and chaach rather than fizzy drinks — the salt in them is the point. Sleep in Khan Market, Lodhi Road or Jangpura on this night: they are five to fifteen minutes from everything on the day-one route, and the streets have real tree cover.
Day two, 5.30am to 10.30am: Mehrauli and the Qutub
Out of the hotel at 5.45 and south to Mehrauli. The Archaeological Park is free and unfenced, so you can walk Rajon ki Baoli, Jamali Kamali and Balban's tomb from first light with parakeets going overhead and nobody else about. Stepwells are genuinely several degrees cooler at the bottom, which is why they were built. Give it ninety minutes and carry a litre each; there is no water tap inside the park and only one chai stall by the Anuvrat Marg gate.
The Qutub complex opens at 7. Be through the gate by 8 and out by 9.30, because the courtyard between the Quwwat-ul-Islam mosque and the Alai Minar has no shade at all once the sun clears the minar. The Iron Pillar and the arcades hold shade longest. Then move straight to Hauz Khas complex, free, where the madrasa cloisters overlook the reservoir and stay tolerable to about ten. Coffee in Champa Gali at Saidulajab by 10.15 and you have banked a second serious morning.
Day two, 11am to 10pm: cold rooms, then the old city after dark
Lunch and then a long indoor stretch again: the Sulabh International Museum of Toilets in Mahavir Enclave is free, air conditioned and genuinely one of the strangest museums anywhere; the National Rail Museum in Chanakyapuri has indoor galleries but its yard exhibits are unusable in June, so go for the halls only. A hammam-style spa or a hotel pool between 2 and 5 is a defensible use of a Delhi afternoon in a heatwave, and most large hotels sell pool day passes at ₹1,500 to ₹3,000.
From 6.30pm take Old Delhi. Chandni Chowk has been closed to motor traffic 9am to 9pm, so the evening walk is rickshaws and pedestrians only; Jama Masjid's courtyard is cool underfoot after seven and the south minaret climb at around ₹100 catches the last light. Eat kebabs in Gali Kababian at 8. Sleep this night in Connaught Place or, if the budget stretches, a restored haveli inside the walled city so the return trip is five minutes rather than forty. Aerocity works if you fly out early, but you lose the evenings.
Where to sleep, and what to check before you book
In June the hotel is doing half the work of the holiday, so screen for three things: split or central air conditioning that is reviewed as actually cold, a pool or at least a shaded courtyard, and a generator, because outer-Delhi power cuts still happen on peak-load evenings. Central and south Delhi — Khan Market, Lodhi Road, Jangpura, Defence Colony, Greater Kailash — has the best tree cover in the city and mid-range rooms at ₹4,500 to ₹9,000. Chanakyapuri's diplomatic-enclave hotels are the coolest streets in Delhi but start higher, ₹12,000 and up.
What to avoid in a heatwave: top-floor Paharganj rooms at ₹1,000 to ₹2,000, which are cheap because the concrete roof radiates all night; anywhere advertising a window air conditioner as a feature; and Old Delhi budget guesthouses without a lift, where you climb four flights each time you return. If you can only afford one upgrade on the whole trip, buy the pool. Two hours in the water at 3pm is what makes the 5.45am alarm possible on the second morning, and the second morning is where this itinerary earns its keep.
Before you book
What people ask before booking Connaught Place.
It is uncomfortable, not mad. Hotel rates fall by 30 to 40 per cent, monuments are almost empty at 7am, and skies are clear rather than the winter fog and smog. The trade is that you get roughly five usable outdoor hours a day, so plan for two sights, not five.
The monsoon usually breaks over Delhi in the last week of June and runs to mid-September, dropping the temperature to 30 to 35°C but adding humidity and waterlogging on roads like Minto Bridge. Late August visits are greener and cheaper; carry sandals you can wade in and allow extra time for every journey.
Two to three litres a person a day in the shade, more if you walk. Buy oral rehydration sachets from any chemist at around ₹20 and take one mid-morning and one at 4pm. Nimbu pani with salt, chaach and aam panna all do the same job; sweet fizzy drinks do not.
Humayun's Tomb, because the chamber and plinth arcades stay cool until mid-morning and the underground site museum next door is fully air conditioned, so you can retreat without leaving the site. Qutub Minar is the opposite: an unshaded sandstone courtyard that becomes unbearable by half past nine in June.
