Surf, weather, safety alerts, and the best beaches for 2026-05-09.
Oahu's south shore is the best bet today for calm, reef-protected waters — ideal for swimming and snorkeling. Ala Moana Beach Park and Magic Island Lagoon offer gentle waves and lifeguard supervision. The windward shores (Kailua, Waimanalo) are windy (13-16 mph from the NE) with moderate surf (3.7 ft) and 100% rain chance, making them better for windsurfing than swimming. North Shore beaches (Sunset Beach, Waimea Bay) have solid surf (5.2-5.7 ft), but brown water advisories remain active — do not enter the water. Tropical storm risk is elevated this season, so check conditions before heading out. Pack a light jacket for showers and breezy conditions.
