Spot intelligence.

Supertubes needs enough south-to-southwest period to wrap Cape St Francis. The same refracted angle lets an offshore wind groom the line down the point.

Character

01

Supertubes is defined by fast right-hand point barrel over sand over lava rock fingers. 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 · 13s+ preferred swell, sw–w offshore and mid tide · section dependent form the profile baseline. SWELLRADAR treats 1.2–3.6 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 high-speed reef sections, sharp rocks and shells, heavy crowd. Local signs and advice always take priority.
