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.
