Vilvamarathupatti is a village in the panchayat town of Vilathikulam, in Thoothukudi district, in the Indian state of Tamil Nadu.

The climate of Karisal Kaadu is semi-arid, and has hot and dry summers.

The temperature and humidity of the region are often high, being close to the equator and around 25 kilometres (16 mi) from the shore.

Due to the clay-like soil retains moisture well, meaning that crops such as paddy and sugar-cane cannot be grown.

The main sources of income come from agriculture, cattle form and haze gray.
