Spot intelligence.

Lakey Peak is calibrated as a two-sided reef peak rather than a generic Sumbawa forecast. South-to-southwest groundswell and an early offshore window receive the strongest fit; tide remains adaptive because the left and right respond differently.

Character

01

Lakey Peak is defined by hollow a-frame peak · longer left and shorter right over shallow coral reef. 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

02

S–SW groundswell swell, n–ne offshore · early before trades and moving mid tide · section dependent form the profile baseline. SWELLRADAR treats 0.9–3.8 m as a working range, not a guarantee of breaking-wave size.

Lineup read

03

This is an advanced profile: positioning, entry and exit should be assessed before committing. Pay particular attention to sharp coral reef, heavy lip impact, strong current on larger swell. Local signs and advice always take priority.

Data note

Model data unavailable

SWELLRADAR withholds numerical conditions, scores and surf windows until a quality-checked marine forecast is available.
