Surf, weather, safety alerts, and the best beaches for 2026-06-18.
Kauai's coastlines are under patchy rain and moderate surf (3.2-4.5ft) today, making ocean entry risky for beginners and families. No active water quality advisories for most beaches, but Waioli Beach Park is under a Brown Water Advisory-avoid water contact there. North Shore beaches like Hanalei Bay and South Shore spots like Poipu Beach Park are your best bets for dry-land scenic walks, wildlife viewing, and picnics. Lifeguards are on duty at Poipu, but ocean conditions remain challenging for inexperienced swimmers. Stay well back from the shoreline and avoid water activities if you're not confident in your skills.
