Almost fully enclosed shell-shaped bay; barely breaks except when a big W/NW swell wraps through the narrow south mouth — the go-to flat-day beginner/SUP spot, not a real swell magnet.

Hazards very weak/inconsistent surf most days · boat traffic near the harbor and inlet · crowded swim/surf shared space in summer
