medium confidenceAvoid the ocean today. Runoff from heavy rain has likely elevated bacteria levels, and surf is choppy. Wait 48–72 hours after the storm passes before swimming. Stick to indoor activities like museums or shopping centers.
Keep kids indoors or at sheltered parks (e.g., Ala Moana Center, Bishop Museum). If you must visit the beach, choose lifeguarded, reef-protected areas like Ala Moana and rinse off thoroughly afterward. Pack rain gear and indoor backup plans.
Ocean conditions are hazardous due to high surf, strong currents, and runoff. Avoid North Shore and windward beaches entirely. Check the Clean Water Branch’s advisory map before considering any water activities: [https://health.hawaii.gov/cwb/](https://health.hawaii.gov/cwb/).
Oahu’s beaches are under advisories due to dangerous ocean conditions. High surf (5–6 ft) and strong southerly winds (20–25 mph) are creating choppy, hazardous waters. Runoff from heavy rain has likely elevated bacteria levels, particularly on windward and south shores. The Ocean Safety Division warns against swimming at North Shore beaches like Waimea Bay and Sunset Beach due to high surf and flash-flood risks. South shore beaches (e.g., Ala Moana, Waikiki) are safer but still pose runoff risks. Avoid discolored or murky water—even if it looks clear, bacteria levels may be unsafe.
Oahu is under a flood watch and high-wind warning through Friday. Heavy rain (4–10 inches forecasted) and gusty southerly winds (25–35 mph) are expected, with the heaviest downpours likely today. Temperatures will hover in the low 70s. The storm system may linger into next week, bringing additional rounds of rain. Flash flooding and landslides are possible, especially in saturated areas like Waialua and Hauula. Officials urge residents and visitors to stay home and avoid unnecessary travel.

A Presidential Disaster Declaration has been approved, providing federal assistance for recovery efforts. Ocean Safety Division has posted advisories for most shorelines—avoid beaches due to high surf, runoff, and elevated bacteria levels. The storm could linger into next week, with additional rain expected.
