The best time to go to Thirunallar is between October and March. This period avoids the intense heat and humidity of other months, offering pleasant weather for temple visits and exploring the area.
During these months, the temperatures are moderate, typically ranging from 20 to 30 degrees Celsius, which is much more comfortable for walking around and participating in religious ceremonies. The skies are generally clear, and there's less chance of rain, making it ideal for outdoor activities and travel.
This time is particularly good for families and older travellers who appreciate comfortable conditions for their pilgrimage. The cooler weather makes the experience of visiting the Saneeswaran Temple, a primary draw to Thirunallar, much more enjoyable, allowing for longer exploration without discomfort.
