East Nusa Tenggara (NTT) is, in many ways, different from the rest of Indonesia. NTT includes 566 islands, of which only 42 are inhabited, and the bulk of the population live on the three main islands of Timor, Flores and Sumba. It is geographically, ethnically and culturally a border area where the transition from Asia to Australia and Micronesia takes places. Deep offshore trenches and inter-island channels allow plenty of swell to hit the southwest-facing coast of Sumba, where waves of consequence get thrown onto the reefs of dead coral, volcanic rock and boulders. Sumba is not for everyone; the food and accommodation are basic and the mixed ethnic population speak 3 different languages. Huge megalithic tombs and thatched, peaked huts dot the landscape, while in the line-up, intrepid travellers are now sampling the oceanic power of this ancient island.
When to Go
Dry season (March-October) is the main surf producer, when generous Indian Ocean swells can sometimes reach 12-15ft (4-5m) in June-August from a SSW- WSW direction. The main trend is the SE trades, which blow-out many exposed spots, especially from June-Sept. Unlike Bali, the trades don’t blow consistently during the day, instead there are on and off windy periods. Obviously, trades gets stronger as the day progress, but sometimes thunderstorms can change wind patterns, so early and late glass-offs are common. Expect many 6-12ft (2-4m) days with windy line-ups, better suited for experienced surfers. Because of the deep ocean trench and direct SW swell exposure, Sumba gets big, with less nooks and crannies than western Nusa Tengarra islands. That’s why the wet season (Nov -April) is also a good time to consider for friendlier conditions at the rights of Tarimbang, Wainukaka or Mangkudu with NW winds being offshore. The Sumba coastline is typically steep rather than cliffs and often has a fringing coral reef. Nusa Tenggara has more extreme tidal range than the rest of Indonesia, making many spots very tide sensitive. There is a big tide and small tide everyday and tidal range can reach 8ft. Finding tide charts is difficult, trust your tide watch. Some spots are best on the bigger spring tides occurring 3 or 4 days before and after new and full moons.

Travel Information
Weather
NTT has a semi-arid climate, with moderately low rainfall and landscape dominated by savannah and steppe. Sumba has a seasonal climate because it lies in the rain-shadow of the Australian continent and receives little rain in the SE monsoon between April and November although West Sumba gets way more rain. West Sumba is green and fertile in the wet season while East Sumba is more dry and mountainous (highest peak is 1,225 m). Temps vary from hot in coastal areas (30-35°C/86º-95ºF)) to very cool in mountainous areas (15-17°C/59º-63ºF).There is a dry season (May to November), and a rainy season (December to April). In many coastal areas not a drop of rain falls during most of the year. The coastal rainfall varies there between 50-200mm (2-8in) a year, up to 1,625mm (65in) in the west Sumba mountains. Boardshorts year round.

Nature and Culture
Sumba is well known for its sandalwood, horses, impressive megalithic tombs and typical hand woven textile ("ikat"). The most spectacular ceremony is the Pasola, the ritual fight with spears featuring hundreds of horsemen. It is a wild martial event, and although the government now insists on blunted spears, serious injuries are common and occasional deaths.
