Dead corals nearer to the shore are very sharp. Booties are a necessity. Tides and currents play an important role in determining surfing conditions in Maldives. All the breaks occur near narrow channels of the atolls. Currents through these channels can be very strong. During the SW monsoon, currents flow outwards at the eastern reef of the atolls where the best surfs occur. Swell lines are generally perfectly straight and clean from the south-east (give or take 5 -7 degrees either side with different swells). Most common surfing conditions are two to four feet, clean, straight, long and perfect. A good swell of five to eight feet is about 75% to 85% likely in a two-week stay. Ten feet waves occur on average three times a year. All the waves hold pretty much the same form in all tides. As tides become bigger they are inclined to become hollow.
