Reading the ocean.
SWELLRADAR is requesting a verified marine run for Outside Left.
Spot intelligence.
This is Outside Left/Terasaq at Gerupuk's southeastern opening, not Outside Right or the protected Inside reef. Roots and Nalua explicitly grade this fast, hollow reef for advanced surfers. Advanced is the minimum independent-recommendation gate, not clearance for every swell; inspect the end section and arrange locally appropriate access before entry.

Reviewed 23 Oct 2026 · not observation-validated
Published sources reviewed by SWELLRADAR, not validation against measured breaking waves. Swell and independently stated wind references are qualitative ranking inputs, not surveyed optima, measured shelter or full acceptance windows. The inherited generic 0.6–3.0 m offshore-model ranking band remains unchanged and unvalidated: not a measured local working range, safe learner range or wave-face conversion. Original approximate map pins and location sources remain. Explicit six-kilometre sea requests do not survey reefs, channels, currents, access or provider-snapped cells. Surf Indonesia's exact Outside Left rows supply SW swell, independently stated E wind and the shallow closeout caution. Its Intermediate label is not allowed to weaken the two local operators' explicit Advanced guidance. Roots describes cliff-side breaking and no channel, while other general guides imply an easier route: no safe channel is promised. Mid tide in the general table and mid/high water in the operator accounts favour avoiding exposed reef, not a surveyed normalized optimum. Seasonal guidance also differs, so no all-season shelter or staffing guarantee is adopted. Tide phase/motion rewards, preferred windows and adaptive fallback remain off.

Character
01Outside Left is defined by left · steep takeoff and hollow sections over sharp reef · shallow inside closeout. The shape can change with swell angle, period and the active section, so the live score should always be paired with a visual check from shore.
Best setup
02SW · qualitative outer-reef reference swell, e · qualitative outside left guide reference and more water over reef · unverified scoring form the profile baseline. SWELLRADAR retains 0.6–3.0 m as an offshore-model ranking band, not a measured local surf limit or a breaking-wave prediction.
Lineup read
03This is an advanced profile: positioning, entry and exit should be assessed before committing. Pay particular attention to shallow sharp-reef closeout, fast hollow takeoff, exposed outer-bay position. Local signs and advice always take priority.
