Besides being shark aware during periods of drought or reduced rainfall, heat waves, and during active La Niña events, take these 5 simple precautions to reduce your risk even further: 1 Don't swim at dawn or dusk — the two times of day when sharks are most active. 2 Don't go farther than knee-deep out into the ocean. (Sharks rarely swim in shallow waters.) 3 If you have a cut or an open wound, stay out of the water. (Blood attracts sharks.) 4 If you notice a lot of small bait fish swimming around, leave the water. Sharks feed on them and may be attracted to the area.
