What is under Les Alcyons Avalanche
Eight kilometres out along its swell window the sea floor drops to 82 m.
Measured, not estimated: NOAA ETOPO 2022 global relief at 15 arc-seconds, about 460 m per cell, sampled along this spot’s own swell window. At that scale the survey sees passes and channels; it cannot see a reef ledge, so nothing here is said about how the wave breaks.
Why 78.5
Seven parts, each normalised 0 to 1 and multiplied by its weight; the sum is scaled so the best spot in the world scores 100. Wave quality and what the spot does on its best days carry more than half of it, which is what separates this from a ranking of where the water is warm.

Sumba has eight spots in this ranking, the best of them inside the world top 50. A cabin is €11,500. The land it sits on is separate, from €6,500 (€9,950 oceanfront), on an 80-year lease that extends at the end. Water, septic and electricity are another €6,500, and furniture is on top, so a finished cabin lands around €28,000 plus the land, payable in instalments.
