Storm recovery continues, but reef-protected spots on Oahu’s south shore are your safest bet for swimming today.
Oahu’s beaches are still recovering from recent Kona Low storms, but south shore spots like Ala Moana Beach Park and Magic Island Lagoon offer calm, clear waters for safe swimming. North Shore beaches (Waimea Bay, Sunset Beach) have moderate surf (3–5 ft) and are not recommended for swimming due to potential runoff and currents. Always check the Clean Water Branch’s advisory map before heading out: [https://health.hawaii.gov/cwb/](https://health.hawaii.gov/cwb/). Expect delays on H-1 freeway due to a recent crash—plan alternate routes if traveling to Waikiki or downtown.

low confidenceStick to enclosed, reef-protected spots like Magic Island Lagoon or Ala Moana’s inner lagoon. Avoid North Shore beaches—surf is moderate (3–5 ft) and unsafe for swimming. Wait 48–72 hours after heavy rain to let runoff clear. Always swim near a lifeguard and check the Clean Water Branch’s advisory map before heading out: [https://health.hawaii.gov/cwb/](https://health.hawaii.gov/cwb/).
Ala Moana and Magic Island Lagoon are your safest bets today. Both have lifeguards, calm waters, and space for kids to play. Rinse off after swimming to avoid skin irritation from lingering runoff. Pack a picnic—these parks have tables, shade, and nearby restrooms. Avoid windward shores like Kailua unless water is clear.
North Shore surf is moderate (3–5 ft), but brown water advisories make swimming unsafe. If you’re set on getting in the water, south shore spots like Ala Moana or Sans Souci are safer, but avoid discolored water. Check the Ocean Safety Division’s beach conditions page for updates: [https://www.oceansafety.honolulu.gov](https://www.oceansafety.honolulu.gov). Rinse off immediately after swimming—bacteria levels may still be elevated.
Oahu’s ocean remains under brown water advisories due to storm runoff, but south shore beaches like Ala Moana and Waikiki are seeing calm to moderate waves (2.5–3 ft) with light winds (5–7 mph from the ENE). These conditions are ideal for swimming if you stay inside the reef and avoid discolored water. Windward spots like Kailua have moderate waves (3 ft), but runoff risks persist, especially near stream mouths. North Shore beaches (Waimea Bay, Sunset Beach) have moderate surf (4–5 ft), making them unsafe for swimming due to potential runoff and currents. Lifeguards are on duty at most major beaches, but always check conditions before entering. No active surf advisories, but caution is advised near river mouths and storm drains.
Oahu is mostly sunny today, with temperatures in the low 70s to mid-70s. Winds are light to moderate (5–7 mph) from the east-northeast, keeping conditions breezy but comfortable. Humidity remains moderate, and no significant rain is expected. Morning fog is possible near windward shores, but skies should clear by midday. The ground is still saturated from recent storms—avoid hiking trails or low-lying areas prone to flooding. Midday is the best time for beach visits, with the sunniest and driest conditions.
Oahu’s recovery from the Kona Low storms continues, with a public health emergency declared to support affected residents. A flipped dump truck on the H-1 freeway caused hours-long traffic delays—expect congestion near downtown and Waikiki. Hawaiian Airlines and Alaska Airlines have merged their reservation systems, which may affect flight bookings and check-ins. HECO is investigating flickering lights in East Oahu, which could indicate lingering electrical issues from the storms.
