Bihar, located in the eastern part of India, experiences a subtropical climate with typical hot summers, a monsoon season, and mild winters. The best time to visit Bihar is during the cooler months from October to March, when the weather remains pleasant and conducive to exploring historical sites and engaging in cultural festivals. During this period, temperatures range from a minimum of 10°C to a maximum of 28°C, providing a comfortable environment for tourists. It's also the ideal time for wildlife enthusiasts to visit the famous Valmiki National Park, as the animals are more visible in the mild weather.
The winter months also coincide with several prominent Bihari festivals such as Chhath Puja, typically celebrated in November, and the Sonepur Cattle Fair, the largest cattle fair in Asia, held in the month of November as well. Visiting during these events offers a unique glimpse into the cultural richness of Bihar. However, it is advisable to avoid the peak summer months from April to June, when the temperature can soar above 40°C making outdoor activities almost unbearable. Furthermore, the monsoon season, which extends from July to September, brings heavy rainfall that can sometimes lead to flooding, disrupting travel plans and outdoor exploration.
