Spot intelligence.

G-Land is treated as a reef zone whose sections have different swell exposure and tide tolerance. South-to-southwest energy and east-to-southeast trades are prerequisites; the adaptive tide profile avoids pretending every section works identically.

Character

01

G-Land is defined by long, fast left reef complex with multiple named sections over lava reef encrusted with coral. 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, e–se offshore trade wind and broad tide range · section and size dependent form the profile baseline. SWELLRADAR treats 1.2–5.2 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 shallow reef, heavy current and cleanup sets, difficult low-tide access. Local signs and advice always take priority.
