Climate Overview
New Delhi experiences a subtropical climate with three distinct seasons. Summer temperatures soar to 40–45°C (104–113°F) from May through June, making outdoor sightseeing exhausting. The monsoon season (July–September) brings heavy rainfall and humidity, flooding some streets and making travel unpredictable. Winter (November–February) is mild and pleasant, with daytime temperatures around 20–25°C (68–77°F), dropping to 5–10°C at night—ideal conditions for exploring.
Best Time to Visit
October through March is undoubtedly the best window. October and early November offer warm days and cool nights, perfect for visiting iconic sites like the Red Fort and India Gate without discomfort. December and January are peak tourist months when prices for hotels and tours increase by 30–50%, but the weather is excellent. February remains pleasant but slightly warmer, with fewer crowds and better deals.
Seasonal Breakdown
Avoid May–September entirely if possible. If visiting during summer, plan indoor activities like museums (National Museum entrance around ₹600/$7) and shopping in air-conditioned markets in Connaught Place. During monsoon, streets near Delhi Gate and around the Yamuna River flood regularly. Winter travelers should pack layers—mornings near Lodhi Garden can feel surprisingly cool. Book accommodations and long-distance trains 2–3 weeks ahead during peak season to secure better rates and availability.
