A riptide is a narrow, fast-moving channel of water that starts near the beach and extends offshore through the line of breaking waves.
Trying to swim against a riptide will only use up your energy; energy you need to survive and escape it.
Keep calm – it is not going to pull you underwater, it’s just going to pull you away from shore. Do NOT try to swim directly into to shore. Swim along the shoreline until you escape the current’s pull. When free from the pull of the current, swim at an angle away from the current toward shore.
