Quick Answer
Secure a tarp against strong winter winds by anchoring it with sturdy stakes, using rope or cordage with a high windage rating, and weighing down the edges with heavy objects.
Choosing the Right Tarp and Anchors
When selecting a tarp, opt for one with a waterproof and UV-resistant coating, and a sturdy reinforced edge. A square or rectangular tarp with a minimum of 8 oz (280 g/m²) fabric weight is recommended. Choose anchors with a diameter of at least 1 inch (2.5 cm) to provide stability in high winds. Aluminum or steel stakes are suitable options, but consider using deadman anchors or snow stakes if you’re in a snowy environment.
Securing the Tarp
Anchoring the tarp requires a combination of stakes, rope, and tension. Stakes should be spaced about 3-4 feet (90-120 cm) apart, depending on the tarp’s size and wind conditions. Use a minimum of 3-4 stakes per edge, with the center stake serving as the anchor point. Use rope or cordage with a breaking strength of at least 1000 pounds (450 kg) to connect the stakes and maintain tension. Apply even tension to ensure the tarp is tight and evenly secured.
Additional Techniques for Extreme Wind
In extreme wind conditions, consider using additional techniques to secure the tarp. Weigh down the edges with heavy objects like rocks, snow anchors, or even a person lying down. Use a guy line system to connect the tarp to a nearby anchor point, such as a tree or a rock outcropping. Maintain a minimum of 2-3 guy lines per corner, with a breaking strength of at least 500 pounds (225 kg) each. Regularly check the tarp’s tension and adjust as needed to ensure it remains secure.
