Yes there is surf on the islands. The south eastern corner of Gili T has surf as does the same location on Gili Air. Gili Meno south east beach also has small swell on occasion. HOWEVER: the swell on all 3 islands are very dependant on weather conditions. The breaks are suitable for beginners as they are mostly beach breaks. More advanced surfers should consider south Lombok which has much better swell but they are primarily reef breaks - so not suitable for beginners.
