Spot intelligence.

Yo-Yo's is a broad two-peak area profile covering Wedge and Hook, not a separate wave system from the dedicated Hook record. Use Hook's dated source-reviewed profile for its peak-specific uncertainties; this older area-level SW/ENE and broad-tide baseline must not override that profile's disabled wind bonus and neutral tide treatment.

Character

01

Yo-Yo's is defined by two right-hand reef peaks: the wedgy wedge and the cleaner hook over 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

SW groundswell swell, e–ene offshore and broad tide range · section dependent form the profile baseline. SWELLRADAR treats 0.7–3.2 m as a working range, not a guarantee of breaking-wave size.

Lineup read

03

Choose a peak that matches your experience and reassess it as tide and crowd change. Pay particular attention to shallow reef on the inside, crowded peaks, overpowered sections on large swell. Local signs and advice always take priority.
