Quick Answer
A waterproof tarp is not always strictly necessary for every camping trip, but it is a highly recommended item for any trip that includes the risk of severe weather, such as thunderstorms, flash floods, or high winds.
Assessing Weather Risks
When planning a camping trip, assess the local weather risks and potential for severe weather events. For example, if the area is prone to flash floods or has a history of tornadoes, a waterproof tarp can be a lifesaver as a makeshift shelter. Consider the time of year, season, and any specific weather conditions that may be present during your trip.
Choosing a Waterproof Tarp
When selecting a waterproof tarp, look for one made of a durable, rip-resistant material with a waterproof coating. A good tarp should be at least 9x12 feet in size to provide adequate coverage for a person or small group. Consider a tarp with grommets and tie-down points to secure it in place. Some popular tarp materials include nylon, polyester, and silicone-coated polyester.
Using a Waterproof Tarp as a Shelter
In the event of severe weather, a waterproof tarp can be used to create a makeshift shelter. Look for a spot with minimal slope and a relatively flat surface. Stakes and guy lines can be used to secure the tarp in place. To create a more stable shelter, use multiple poles and tie them to the tarp with rope or cordage. For added protection, consider digging a shallow trench around the perimeter of the shelter to prevent water from accumulating.
