Beach Safety During Lightning Storms

Every year lightning strikes kill or injure beach-goers around the world. If thunder can be heard then lightning is present. These simple steps can help save your life:
  • Obey posted closures.
  • Retreat to your car or other shelter and wait out the storm.
  • Do not use the showers as you leave the beach during a storm.
  • If you are caught in an open area, crouch on the balls of your feet and lean forward with your hands on your knees. Do not lie down or put your hands on the ground.
  • Sound travels a million times slower than light. When you see a flash, time the seconds it takes to hear the thunder. A 5-second difference between the lightning flash and the thunder means the lightning struck 1 mile away. For each additional 5 seconds the strike is another mile away.
