Ala Moana Beach Park is about 15 minutes from HNL and has a reef-protected lagoon with moderate water quality. Ko Olina Lagoons are 20 minutes west with low bacteria risk and calm water. For quick stops, Ewa Beach is closest but has moderate water quality.
Waikiki is about 25-40 minutes from HNL depending on traffic. Rush hour traffic (7-9am, 3-6pm) can add significant time. Ala Moana Beach is a closer option at about 15 minutes.
Yes. Several beaches are within 15-20 minutes of the airport. Pack a bag with swimwear accessible in your carry-on for departure day visits. Consider luggage storage services near Waikiki.
The Hawaii Department of Health recommends staying out of the ocean for at least 72 hours after heavy rain, even if the water looks clear. Bacteria and pollutants from runoff can linger in the water longer than the brown color does.

Safe to Swim Hawaii is an independent passion project — it is not affiliated with the Hawaii Department of Health, O'ahu beaches, or any government agency or hotel brand. Water quality ratings on this site are estimates based on publicly available testing data and geographic analysis. They are not real-time measurements and may not reflect current conditions. “No DOH Alerts” means no advisory is currently posted — it does not mean the water was tested and found safe. DOH only monitors a fraction of Hawaii’s beaches, and some areas have no regular testing at all.
Always verify current water quality conditions with the Hawaii Department of Health Clean Water Branch before entering the water. This site is for informational purposes only and should not be the sole basis for any swimming decisions.
This site is a work in progress and we want to make it better. If you notice something that isn’t working right, have a suggestion, or want to share local knowledge about a beach, please reach out.
When in doubt, don’t go out. 🤙
