But even a beautiful beach has dangers especially for the unaware. Look at the information sign on the lifeguard beach or Ask a lifeguard or ranger. For your protection, relatively safe access to the sandbars on the lifeguard protected beach will be marked with black flags. Swim between the flags and stay in line with them on the sandbar. When the black flags are down, do not attempt to go to the sandbar.
Onshore winds cause waves.
Because ocean winds vary, waves change from day to day. All waves deserve respect. Body surfing and swim fins are allowed in the lifeguard protected beach. Do not try to ride waves that are too forceful for your level of skill. To escape the wave's great force, duck under or retreat from breaking waves.
