Spot intelligence.

Waimea is dormant until genuine big-wave energy arrives. At size, the bay circulation and shorebreak are as consequential as the outer take-off.

Character

01

Waimea Bay is defined by big-wave right with pinballs inside over deep-water bay over reef and sand. 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

WNW–NW swell, ene–s light offshore and mid tide form the profile baseline. SWELLRADAR treats 5.5–12.0 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 expert big-wave conditions, powerful central rip, extreme shorebreak. Local signs and advice always take priority.
