Spot intelligence.

Cow Bombie is deliberately modelled as an expert-only big-wave break, not a normal Margaret River reef. Large long-period west-southwest energy and east-to-southeast wind dominate the score; tide is secondary to swell, wind and rescue readiness.

Character

01

Cow Bombie is defined by open-ocean big-wave bombora about two kilometres offshore over deep offshore reef and bombora. 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–W long-period swell · WSW preferred swell, e–se offshore and all tides · wind and swell dominant form the profile baseline. SWELLRADAR treats 4.0–10.0 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 extreme wave power, two-kilometre offshore lineup, jet-ski and rescue logistics. Local signs and advice always take priority.

Data note

Model data unavailable

SWELLRADAR withholds numerical conditions, scores and surf windows until a quality-checked marine forecast is available.
