Sumbawa, West Timor and Sumba host a multitude of quality waves. Mostly shallow, left breaking reef breaks such as Super Suck and Scar Reef which are aptly named. These hoover up the in-season swells between April and October which swing up from the Roaring 40s and march south-west across the Indian Ocean. These combine with light trade winds blowing from the south-east and classic reef setups. Even during the off season when the trade winds switch to west and north-west there are still classic waves to be had especially on the pacific side and the swells are still regular. Sea temperatures remain steady at around 28Â°C or 82Â°F.
