Peak Season
Peak season brings the best weather but also the highest prices and biggest crowds. Book accommodation and popular attractions well in advance. Hotel Metro Heights fills up quickly during this period.
Shoulder Season
The sweet spot for most travellers. Weather is still good, prices drop, and you can actually get a table at popular restaurants without a reservation. This is when most experienced travellers visit New Delhi.
Off Season
Lower prices and empty streets, but weather can be unpredictable. Some attractions may have reduced hours. If you don’t mind a bit of rain or cold, this is when New Delhi feels most authentic.
Month-by-Month Quick Guide
January-March: Check seasonal conditions for New Delhi. Can be quieter and cheaper.
April-June: Often ideal conditions. Book early if visiting during holidays.
July-September: Peak summer period in many destinations. Expect crowds and higher prices.
October-December: Shoulder into off-season. Often excellent value with mild weather.
October to March: Peak Travel Window
October through March is when Delhi looks and feels its best. Daytime temperatures sit between 20 and 28 C, evenings drop to 8 to 15 C in December and January. Pack a fleece for early morning auto-rickshaw rides and rooftop dinners. October sees Dussehra, November brings Diwali (book at least 6 weeks ahead, prices climb 30 to 50 percent), and February is wedding season city-wide.
Air quality is the trade-off. November through January typically sees AQI in the 200 to 400 range. If you are sensitive to pollution, visit February or March instead. Hotel Metro Heights has air purifiers in the rooms and a sealed lobby.
April to June: Hot Season
April starts at 35 C and June regularly hits 45 C. Sightseeing must happen before 11 AM or after 5 PM. The upside: hotel rates drop 30 to 50 percent, the Taj Mahal day trip is uncrowded, and rooftop restaurants finally fill up after sunset.
If you visit in May or June, plan a daily afternoon nap or museum visit (the National Museum on Janpath is air conditioned and runs 650 INR for foreigners). Carry a 1.5 litre bottle of water everywhere, refill from sealed Bisleri (40 INR for 2 litres at Aggarwal Stores).
July to September: Monsoon
Monsoon brings 200 to 250 mm of rain spread across about 20 wet days. Streets in Old Delhi flood during heavy showers; carry a cheap 80 INR umbrella from any Paharganj kiosk. Temperatures drop to 28 to 33 C, humidity climbs to 80 percent, and Lodhi Garden looks gorgeous after a downpour.
Hotel rates are at their lowest. Flights to Goa are cheap because the Arabian Sea coast is closed for monsoon, but Himachal and Uttarakhand are at peak risk for landslides through August. The India Meteorological Department issues 24 to 48 hour rain warnings worth tracking.
Festival Calendar Worth Planning Around
Holi falls in March and shuts most of central Delhi for the day. Diwali in October or November lights up Connaught Place and Karol Bagh; rooftop dinners book out a month in advance. Republic Day on January 26 closes Rajpath and India Gate to the public for the parade rehearsals from January 18 onward.
Ramzan/Ramadan moves through the calendar each year. During the month, Jama Masjid in Old Delhi serves iftar at sundown and the Matia Mahal lane stays open until 2 AM with kebab carts running at full tilt.
Quick Month-by-Month Verdict
October: Best month overall. 22 to 30 C, post-monsoon greenery, Dussehra. November: Diwali energy, but smog rises. December and January: Cool and crisp, but morning fog can delay flights. February: Sweet spot for clear skies and reasonable temperatures. March: Holi week is wild, second half is lovely. April: Heating up but still doable. May and June: Punishing heat. July to September: Monsoon, heavy rain, lowest prices.
