Conditions
Modelled swell, wind, tide, and a seven-day outlook. This is a forecast, not a live observation at the reef.
An East Sumba surf zone centred on Tarimbang Bay — not a single left reef. The headline is Miller’s Right, a boat-access cluster of fun-to-hollow rights under the headland, with camps on the bay for a remote, still-empty Sumba base.
Miller’s Rights suit strong intermediates; hollow inside sections step up for advanced shortboarders. Confirm boat logistics with your camp.
Board & level fit
Longboard · medium confidence
Longer, less critical walls can work with a longboard when the point is small and clean.
Do not treat the deeper take-off options as a longboard recommendation.
Mid Length · medium confidence
Long, manoeuvrable right-hand walls make a mid-length a strong default.
Shortboard · medium confidence
More powerful and hollow sections reward a responsive shortboard.
Intermediate · medium confidence
The long open walls can suit strong intermediates when conditions are manageable.
Advanced · medium confidence
Deeper take-offs and more powerful sections raise the demand.
This is evidence-led discovery guidance, not a safety rating. Swell, tide, wind, reef depth, and section choice can change the fit.
