Safety notes
US State Dept: Baja California Sur, Level 2 (verify)
- Pacific surf is stronger than the Caribbean: watch the beach flags and rip currents.
- Eastern Pacific hurricane season peaks Aug–Oct.
- Most Pacific-side and many corridor beaches are unsafe for swimming; look for Blue Flag beaches like Chileno and Santa María.
Check official advisories and local flags before swimming. Decomposing sargassum releases hydrogen sulfide; avoid heavy piles.
