Nipussi is an easy-going left reef break on Siberut Island in the Mentawai chain, set against a beautiful tropical backdrop. The wave is one of the more accessible breaks in the Mentawais, making it ideal for intermediate surfers who want to experience the islands' renowned water quality and scenery without the intensity of expert-level breaks. A great warm-up or cool-down spot during Mentawai charter trips.
