Hotel Pool vs. Beach

• It rained heavily in the last 72 hours — bacteria levels spike dramatically after storms
• A brown water advisory is posted — runoff is actively contaminating nearshore waters
• The ocean looks brown, murky, or discolored — your eyes are a reliable indicator
• High surf warning is active — dangerous wave conditions
• Jellyfish are reported — box jellyfish arrive 8-12 days after a full moon on Oʻahu
• You are with very young children — calm, predictable pool water is lower risk
• Someone in your group has open wounds — ocean bacteria can cause serious infection

• No rain for 3+ days — bacteria levels have returned to baseline
• Water is clear and blue — good visual indicator of acceptable quality
• No DOH advisories posted for your beach
• Calm conditions — small waves, no strong currents
• Lifeguards are on duty — added safety layer
• You want to experience Hawaiʻi's incredible marine life and natural beauty

When you do choose the pool, these Hawaiʻi resorts offer world-class pool experiences that can easily fill a day:

Grand Wailea (Maui) — Nine interconnected pools with slides, a rope swing, rapids, caves, and a lazy river. One of the most elaborate pool systems in the state.

Hilton Waikoloa Village (Big Island) — Extensive pool area with waterslides, a saltwater lagoon, and a pool with a current for floating.

Aulani Disney Resort (Oʻahu) — Family-oriented pool area with a lazy river, waterslides, and character interactions.

Grand Hyatt Kauaʻi — Multi-level pool with a 150-foot waterslide and a separate saltwater swimming lagoon.

Before heading to the beach, run through this quick checklist:

1. Has it rained heavily in the last 72 hours? If yes → choose the pool
2. Are there any DOH advisories posted? Check safetoswimhawaii.com or the DOH Clean Water Branch
3. When you arrive, does the water look clear? If brown or murky → choose the pool
4. Are there lifeguards on duty? Important factor for families with children
5. What is the surf forecast? High surf can make otherwise calm beaches dangerous

If all conditions are favorable, enjoy the ocean. Hawaiʻi's beaches are extraordinary when conditions are right. But never feel bad about choosing the pool — it is the smart decision when conditions are poor.
