Character
01Cave is defined by extremely hollow right-hand slab over very shallow detached reef plate. 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
02N–NW swell, se–ne offshore and high tide only form the profile baseline. SWELLRADAR treats 1.0–2.5 m as a working range, not a guarantee of breaking-wave size.
Lineup read
03This is an advanced profile: positioning, entry and exit should be assessed before committing. Pay particular attention to extremely shallow reef, violent suction and impact zone, technical entry and exit. Local signs and advice always take priority.
