Can tall grass provide shelter from lightning strikes?

Understanding the Risk

Tall grass can provide some protection from lightning strikes in the form of a “leader strike,” where the lightning bolt strikes the ground near the tall grass and then arcs to a nearby object. However, this type of strike is still dangerous and can cause severe injury or death. To put the risk into perspective, a tall grass field is roughly 5-10 times more likely to be struck by lightning than a metal building.

Safety Considerations

While tall grass may offer some protection, it is essential to understand that the odds of being struck are still relatively high. If you find yourself in a situation where you are in a tall grass field and a lightning storm is approaching, the best course of action is to seek shelter in a low-lying area, such as a depression or a ditch. This will reduce your risk of being struck by a leader strike. It is also crucial to avoid being in a tall grass field during the peak lightning season, which is typically during the summer months in the United States.

Lightning Strike Safety Techniques

If you are caught in a lightning storm with no access to a building, the following techniques can help minimize your risk of being struck: crouch low to the ground with your feet together and your head down; avoid being in an area with tall objects or bodies of water; and avoid being near metal objects, such as fence posts or golf clubs. By following these techniques and understanding the risks associated with tall grass, you can reduce your chances of being injured or killed by a lightning strike.
