Spot intelligence.

Lowers is a bilateral cobblestone peak with unusually good shape across a broad middle tide. The score now heavily rewards south-to-southwest swell and offshore east-to-northeast wind instead of treating all Pacific energy equally.

Character

01

Lower Trestles is defined by high-performance left + right peak over cobblestone reef and rivermouth rock. 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 swell, e–ne offshore and medium-low to medium-high form the profile baseline. SWELLRADAR treats 0.8–3.2 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 very heavy crowd, competitive takeoff, rock and cobblestone bottom. Local signs and advice always take priority.
