Green = Low Hazard  Calm Conditions. Exercise caution.

Yellow = Medium Hazard  Moderate surf and/or currents.

Single Red = High Hazard  High surf and/or strong currents

Double Red = Extreme Hazard  Water closed to the public.

A red flag flying on a public beach means strong currents, possibly undertows, are present.  Do not swim when red flags are present.  If you are caught in a current or undertow, relax as much as possible until the current brings you back to the surface.  Swim parallel to the shore until you are free of the current.  Never swim alone.

Purple = Dangerous marine life   Sharks, jellyfish, or other harmful marine life present

*Absence of Flags DOES NOT assure safe waters.
