Kokrobite beach is wide, sandy, and significantly cleaner than the beaches closer to Accra. The Atlantic surf can be strong — riptides form along the beach, particularly near the channel mouths, and several drownings have occurred. Swim parallel to shore if you get caught in a rip, not against it. The safe swimming areas are marked informally by local knowledge; ask before going in if you're unsure.
Outside the water, the beach is pleasant: hawkers sell cold drinks and grilled corn, fishing boats are hauled up above the tide line, and the palms behind the beach provide afternoon shade. Mornings are best — before the sun gets intense and before the weekend crowds from Accra arrive. Sunsets over the ocean are reliably good.
