What a rip current does
A rip current moves water away from shore through the surf zone. It can form near breaks in sandbars and alongside piers, jetties and other structures. A rip current does not pull a swimmer underwater; the danger comes from being carried away from shore, becoming exhausted and trying to fight the current head-on.
If you are caught in a rip current
Stay calm and conserve energy. Do not try to overpower the current by swimming directly back toward shore.
Move out of the current. Swim in a direction following the shoreline, or toward breaking waves, and then angle back toward the beach once you are free of the seaward flow.
If you cannot escape, float or tread water. Keep your airway clear, conserve energy, and wave and yell for help.
If someone else is in trouble
Get a lifeguard immediately. If no lifeguard is present, call 911. Direct the person to move parallel to the shoreline if they can hear you and throw them something that floats. Do not enter the water without flotation; rescuers can become victims themselves.
Before you enter the Gulf
Sunny weather can still produce dangerous currents
Blue skies and warm water do not guarantee safe swimming conditions. Rip currents can occur on otherwise pleasant beach days, and swell from distant storms or tropical systems can increase the hazard even when the storm itself is far away.
