1. Winter & Spring (October to March): The Peak Sightseeing Season
Overview: This is widely recognized as the premier window to experience Delhi. Clear skies, comfortable daytime warmth, and cool evenings make visiting the top places to visit in Delhi, walking through Old Delhi bazaars, and exploring historic garden complexes effortless. If you are on a tight schedule, this season works best whether you follow a Delhi 1 day itinerary, a Delhi 2 day itinerary, or a broader Delhi 3 day itinerary.
- October & November (Autumn/Post-Monsoon): Days are warm (28°C–32°C / 82°F–90°F) and nights grow cool. Major national celebrations like Dussehra and Diwali transform the city into a festival of lights, making it a great time to browse famous markets in Delhi.
- December & January (Peak Winter): Temperatures can drop to 5°C (41°F) or lower at night. Dense morning fog is common, which can cause minor train or flight delays. The landmark Republic Day Parade takes place on January 26th along Kartavya Path near India Gate.
- February & March (Spring): Bright, sunny days (20°C–26°C / 68°F–79°F) make this arguably the most comfortable weather window for outdoor things to do in Delhi. The Rashtrapati Bhavan (Amrit Udyan) gardens open to the public, culminating in the vibrant Holi festival of colors in March.
2. Summer (April to June): Low Season for Budget Travelers
Overview: Summer brings extreme heat to Northern India, with daytime temperatures routinely exceeding 40°C (104°F) in May and June. Dry, hot winds known locally as the Loo blow across the plain during afternoon hours.
- Why Visit in Summer? Hotel prices drop significantly (up to 40%–50% off peak rates), making it easy to decide where to stay in Delhi affordably. Popular historical monuments like the Qutub Minar Complex, Red Fort, and Humayun’s Tomb have minimal crowds.

- Atmosphere: Delhi’s urban forests, historical parks like Lodhi Garden and Sunder Nursery, and heritage ruins like Purana Qila turn vibrant green, creating picturesque backdrops for photography.
- Travel Consideration: Heavy downpours can lead to temporary traffic congestion and waterlogging in low-lying roads. Read our guide on how to get around Delhi and check our Delhi Metro guide for tourists to use the rapid transit network and bypass surface traffic during rainy spells.

Essential Packing & Practical Tips for Global Visitors
1. Seasonal Clothing Guidelines
- October to March Packing: Pack light cottons for daytime, but bring a warm jacket, wool scarf, and sweater for chilly winter mornings and evenings (especially December/January when central heating is uncommon in standard buildings). When visiting religious landmarks like Jama Masjid, Lotus Temple, or Akshardham Temple, ensure your shoulders and knees are covered.
- April to September Packing: Lightweight, breathable linens or loose cotton items are essential. Bring sun protection (hat, sunglasses, high-SPF sunscreen) and an umbrella/raincoat for monsoon months. For more recommendations, review our complete list of Delhi travel tips.
2. Flight & Hotel Booking Strategy
- Peak Season Planning: If visiting between November and February, review how to reach Delhi and pre-book flight tickets and hotels 2 to 3 months in advance to secure optimal rates in central areas like Connaught Place, Aerocity, or South Delhi.
- Budget Travelers: Look for shoulder-season deals in late March or early October, where mild weather overlaps with moderate hotel pricing.
3. Navigating Winter Fog & Air Quality
- Morning Visibility: Morning fog in December and January can delay early morning flights and long-distance trains. Allow cushion time in multi-city itineraries.
- Health & AQI Preparation: Air quality index (AQI) levels fluctuate in late autumn (November/December). International travelers sensitive to dust or air shifts may wish to pack high-grade N95 masks or stay indoors during peak morning smog hours.
