Seger Beach in Central Lombok

Bau Nyale is a sea worm catching ceremony carried out by the people of South Lombok every year. Bau means catching, and nyale is a type of worm that only appears once a year in certain locations on the south coast of Lombok Island. Local residents believe that Nyale has good luck which can bring prosperity to those who value it and evil to those who underestimate it. The Bau Nyale ceremony is held on the 20th of the 10th month and the beginning of the Sasak year. This time is marked by the rising of the star "Rowot", which is associated with agriculture. According to Sasak calculations, the 1st month begins on May 25 and each month is counted as 30 days. When compared with the Gregorian year, the 10th month falls around February.

People believe that if a lot of nyale comes out, it means that agriculture is successful. They throw the leaves used to wrap the nyale into the rice fields so that the rice crop will be abundant. Until now, this legend still lives among the Sasak tribe in South Lombok. And the story of Mandalika has become a tradition, namely catching sea worms which are often found on these beaches in certain months.
