Best materials for a lightning-safe shelter outdoors?

May 8, 2026

Quick Answer

For a lightning-safe shelter, use non-conductive materials such as wood, fabric, or plastic. Avoid metal, water, and tall objects. A crouch position in a ditch or depression is also recommended.

Choosing Non-Conductive Materials

When selecting materials for a lightning-safe shelter, look for non-conductive options such as wood, fabric, or plastic. Wood, specifically hardwoods like oak or maple, can provide a sturdy structure. Fabric, such as nylon or polyester, can be used for a lightweight and waterproof shelter. Plastic tarps or sheets are also effective, but be sure to choose a heavy-duty option that can withstand wind and rain.

Designing a Safe Shelter

Aim to create a simple, low-profile shelter that won’t attract lightning. Avoid using metal nails or screws, and opt for wooden stakes or rocks to secure the structure. Keep the shelter’s dimensions small, ideally around 8-10 feet in diameter, to minimize the lightning’s strike area. Consider a lean-to design, which can be built using a few wooden poles and a tarp or fabric.

Crouching in Safety

If you can’t find suitable materials for a shelter, consider crouching in a safe position to reduce your risk of being struck. Choose a depression or ditch that’s at least 6 inches deep, and get into a crouched position with your feet together and your head down. Avoid standing near water, as it’s a prime target for lightning. Also, steer clear of tall objects like trees or power lines, as they can attract lightning.
