Safety notes
Domestic travel (no State Dept advisory)

- 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.
- Lahaina is still rebuilding after the 2023 fire: respect closed areas.
- Afternoon trade winds make west Maui channels choppy.
Check official advisories and local flags before swimming. Decomposing sargassum releases hydrogen sulfide; avoid heavy piles.
