The short answer
When to go to Sitamarhi
The best window is November to February, when days are dry and mild and temple walking is comfortable. Mornings can be foggy in December and January, so allow slack for trains. October and March are acceptable but warm by midday. April to June is very hot, and July to September is the monsoon with flooding risk. Older travellers should avoid the festival peaks of Ram Navami, Janaki Navami and Vivah Panchami unless devotion outweighs comfort. Climate figures are from Darbhanga, the nearest IMD station with a published table.
