The best time to visit the Tomb of Sher Shah Suri, an eminent historical monument located in Sasaram, Bihar, India, is during the cooler months of October to March. During this period, the climate in Bihar is pleasant, and the temperatures are conducive for outdoor activities and sightseeing, with the average temperature ranging between 10°C and 25°C. The cooler weather ensures a comfortable visit, as the heat in the other months, particularly April to June, can be quite intense, often exceeding 40°C, which might hinder your exploration of the grand mausoleum and its surroundings.
Besides comfortable weather, the winter months may coincide with several regional festivals that could enhance your travel experience. Traveling in early March can also provide the opportunity to witness the vibrant festival of Holi, celebrated across north India with great fervor. However, it's advisable to check the local schedule and opening times of the tomb before planning your visit, as timings may change due to various reasons, such as conservation work or local holidays. Whether you are an enthusiast of history, architecture, or culture, a visit to this stunning example of Indo-Islamic architecture is best enjoyed when the weather is at its most welcoming.
