Spot intelligence.

Inamuragasaki is intentionally kept selective: ordinary Shonan windswell should not promote it like a daily beachbreak. It scores best on genuine south typhoon energy with north wind, while all-tide guidance remains adaptive.

Character

01

Inamuragasaki is defined by inconsistent south-facing reef peak that activates on typhoon swell over rock reef and mixed nearshore bottom. 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 typhoon swell swell, n offshore and broad tide range form the profile baseline. SWELLRADAR treats 0.7–2.8 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 rock and reef impact, severe crowd when active, cross-shore wind exposure. Local signs and advice always take priority.
