The best time to visit Chidambaram is in February, during Mahashivratri. It is the time for Natyanjali Dance Festival, which is dedicated to the Tandav Shiva Nataraj. The festival invites the finest classical dancers for performing in the temple. Otherwise you can visit the place between January and March for the sightseeing. Avoid summer as it is very hot and the temperature reaches up to 38°C.
