About
Kosi Bay is an exposed beach and reef surfing area known for fairly consistent surf and an uncrowded, wilderness-style experience. Sessions are most favorable when a southeast swell arrives and the northwest wind is offshore, helping groom the waves. The break can include both sand and reef influences, and conditions are described as good to moderate depending on the day. While the spot can handle larger swells, strong currents can make waves feel heavier—particularly near the estuary mouth. Safety is a major consideration. Reported hazards include sharks and rocks, and multiple sources emphasize being especially cautious around the estuary mouth. The location is remote with no on-site lifeguards and no dedicated immediate rescue service; emergency services are not available directly at the beach, so planning and self-sufficiency are essential. Access is typically via the surrounding beach network, but reaching the mouth area is restricted by permits and 4x4 requirements. The spot’s remoteness, limited parking at the mouth, and lack of on-site services (such as food facilities and equipment rental) mean riders should bring everything they need and travel prepared.
