Surf, weather, safety alerts, and the best beaches for 2026-05-12.
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 (20+ mph from the ENE) with moderate surf (4.6 ft) and no rain, making them better for windsurfing than swimming. North Shore beaches (Sunset Beach, Waimea Bay) have solid surf (4.8-5.3 ft), but brown water advisories remain active — do not enter the water. Pack a light jacket for breezy conditions and check advisories before heading out.
