• Swim coach Lucas Taub heroically rescued a father and daughter from a rip current in Oceanside, California.
• Rip currents are dangerous, fast-moving channels of water that flow away from the shore and can reach speeds of up to 8 feet per second.
• Beachgoers should swim at lifeguard-protected beaches, heed warnings, and know how to escape a rip current by swimming parallel to the shore.
