St Agnes.

Trevaunance Cove - known locally as 'Aggie' - sits in a sheltered bay below the village of St Agnes and produces powerful peaks off a mixed rock ledge and sand bottom. Rights peel toward the Maddocks Rocks end of the cove with more punch and occasional hollow sections in stronger swells; shorter lefts form toward the harbour side. The cove is comparatively protected, receiving roughly two-thirds of the wave height found at nearby Porthtowan, which makes it one of the few spots on this stretch still functioning in big SW conditions when neighbouring beaches are blown out or unrideable. West to W-SW swell is the sweet spot; mid tide tends to organise the banks best, though low to mid also works - low tide pushes the wave to heavier and more plunging. Spring high tides can flood the bay with surging, shapeless water. Surf schools operate here because the smaller days genuinely suit supervised learners, but heavier swells produce waves that demand real experience to navigate safely. Access is via Quay Road and a steep slipway. The lineup is consistently crowded when the surf is on, and a degree of localism is present - arrive with appropriate respect. A rip runs from mid-beach toward the harbour, and the right-hand rock sections are exposed at lower tides.
