Updated: March 2026
December is a excellent time to visit Delhi (8/10). With 10 daily sunshine hours and only 1 rain days, this month delivers genuinely reliable outdoor conditions, ranking it 9th sunniest of the year in Delhi. Beach and outdoor-focused visitors will find December ideal, though hotel prices reflect demand and popular sites get crowded by mid-morning. January offers a similar profile at lower hotel rates if dates are flexible. The main practical note: Delhi's popular sites are busiest between 10am and 3pm regardless of season. Arriving at opening time or after 4pm makes a significant difference to the experience. Planning tips: book accommodation at least 6-8 weeks ahead, as popular hotels fill quickly during December. Purchasing skip-the-line tickets for major attractions in advance saves meaningful time. If you have flexibility, arriving a few days before or after peak weekends reduces both crowds and prices noticeably.
December sits at a particular moment in Delhi's seasonal arc. Temperatures average 22°C during the day, placing this month in a comfortable middle band, noticeably warmer than the depths of winter but without midsummer extremes. Against the seasonal backdrop, 1 rainy days and 10 sunshine hours per day help calibrate expectations for what actually awaits on the ground.

The 13°C day-to-night swing is large enough to require a deliberate layering strategy, what works at noon will be noticeably cold by 10pm. Humidity averages 70%, which is comfortable for most visitors. On warmer days, lighter fabrics help with the mild stickiness in the afternoon. The UV index of 2 is low, meaning sun exposure is minimal concern and sunscreen is largely optional. Winds are calm at an average 12 km/h, so wind-chill is not a factor in planning your clothing.

Packing for Delhi in December means dressing for 22°C days and 9°C evenings. A light cotton tee with a casual overshirt works well at 22°C, the overshirt doubles as a layer for air-conditioned venues. Evenings drop 13°C to around 9°C, a notable shift that catches underprepared visitors off guard. Pack a dedicated evening layer. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. For temple and religious site visits, carry a lightweight scarf or sarong to cover shoulders and knees, required at most major sites across the region.
Local tip: Temple and religious site visits require covered shoulders and knees in most of Delhi's heritage areas. A lightweight scarf or sarong weighs almost nothing and solves the problem instantly.
December has no major festivals or public holidays in Delhi, which is one of its practical advantages for independent travellers. Attractions run at lower capacity than during peak event periods, queues are shorter, and accommodation is easier to find without needing to book many months in advance. Local restaurants, markets, and transport operate at a relaxed pace, making this an ideal time for visitors who prefer a more authentic, unhurried experience of everyday city life rather than large crowds drawn in by a single major headline event.
Based on 22°C average highs and 1 rainy days
December in Delhi reflects a mid-latitude climate pattern, with temperatures averaging 22°C by day and 9°C overnight. The city sits at 29 degrees north latitude, where the balance between solar radiation and heat loss drives conditions that are neither extreme nor static. Conditions occupy the comfortable middle band of the annual temperature range, where outdoor activity is feasible without the extremes of midsummer heat or midwinter cold. Day-to-night temperature variation of 13°C is large and requires deliberate layering. Climate data: Open-Meteo ERA5 (1991–2020).
Sunshine Hours
The average number of hours per day with direct sunlight. Calculated from satellite measurements. Days with more than 7 hours of sunshine are ideal for outdoor activities. Under 3 hours means overcast conditions dominate.
UV Index
A scale from 0-11+ measuring ultraviolet radiation intensity. UV 0-2: Minimal risk. UV 3-5: Moderate, wear sunscreen. UV 6-7: High, hat and SPF 30+ essential. UV 8-10: Very High, limit midday exposure. UV 11+: Extreme, seek shade between 10am-4pm.
Rain Days
A rain day is counted when precipitation exceeds 0.1mm. This threshold captures even light drizzle. Unlike total rainfall in mm, rain days tells you how often you might need an umbrella, which is useful for planning outdoor activities.
