Look for colored flags that indicate safe swimming areas and dangerous conditions.

Patrolled beaches will display two colored flags indicating the safest area for ocean swimming; the colors of these flags may vary depending on where you are. Also, flags in particular colors can be used to indicate certain conditions. High risk and dangerous condition flags should be clearly displayed as a warning to swimmers. If you are unsure what each flag represents at the beach where you are, be sure to ask the lifeguard on duty for a clear explanation. This is especially important if you are visiting a beach in another country, so that you are clear on the local indicators of ocean safety.
