The most popular time to visit Delhi is during the peak season from July to September, when the city comes alive with vibrant festivals and cultural events. This period offers travellers a chance to immerse themselves in the rich history and bustling atmosphere of the capital. While the weather can be quite humid, the monsoon rains bring a refreshing change, making it easier to explore the city's landmarks, such as the majestic Red Fort and the serene gardens of Lodhi.
July is particularly appealing, as it marks the height of the monsoon season, which can offer a unique perspective of the city's beauty. Visitors can enjoy cooler temperatures, usually in the mid-20s Celsius, great for outdoor sightseeing, especially in the mornings and evenings when the air is fresher.
For those seeking a more budget-friendly experience, consider visiting in December. Though this month is outside the peak season, it still provides a delightful climate, with temperatures ranging from the low to mid-teens Celsius. This allows for comfortable exploration of the city's famous street food scene and historical sites without the bustling crowds.
