The Nav Nalanda Mahavihara (NNM) in Nalanda, Bihar, is an esteemed institution of learning and a site of historical significance. The best time to visit this place is during the cooler months from October to March. During this period, the weather in Bihar is pleasant, with the temperature ranging from a comfortable 12°C to 27°C. It is the ideal climate for tourists to explore the ancient ruins and museum without the discomfort of the sweltering heat that is characteristic of the Indian summer.
If you plan to sightsee and delve into the rich historical background of the Mahavihara, this period is optimal as it avoids the monsoon season, which can see heavy rains from June to September, potentially hampering travel plans and outdoor activities. Moreover, winters in Nalanda are not too harsh, making daytime explorations under the clear blue skies a delightful experience. Festivals like Diwali and Holi, which usually fall within these months, add a vibrant cultural dimension to your visit, but it's wise to book your accommodations in advance as these times could see a surge in visitors.
