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.
Vog (volcanic haze) can affect air quality; check the Hawaiʻi Volcano Observatory.
Hilo side is much wetter than the Kona–Kohala resort coast.

Check official advisories and local flags before swimming. Decomposing sargassum releases hydrogen sulfide; avoid heavy piles.
