Safety notes
Domestic travel (no State Dept advisory)
- Winter swells (Nov–Mar) make north- and west-facing shores dangerous; summer swells hit south shores.
- Shorebreak and rip currents cause most visitor injuries: swim at lifeguarded beaches.
- Hawaiʻi bans sunscreens with oxybenzone and octinoxate.
- Stay 50 ft from monk seals and 10 ft from sea turtles.
- Box jellyfish can reach leeward beaches 8–10 days after a full moon.
Check official advisories and local flags before swimming. Decomposing sargassum releases hydrogen sulfide; avoid heavy piles.
