Quick Answer
To ensure a tarp stays secure in rainy conditions, you'll need to adjust its tension and angle to maximize water runoff and prevent pooling. This may involve tightening or loosening the guylines, repositioning the tarp, or using additional stakes.
Securing the Tarp
Tighten the guylines to a 45-degree angle, which will help water run off the tarp. If the tarp is too loose, water can collect and seep under the fabric. Use a tensioning tool or a stick to adjust the guylines evenly.
Angling the Tarp
Adjust the tarp’s angle to a slight pitch, ideally around 10-15 degrees. This will allow water to run off the tarp without pooling. If the tarp is too flat, water will collect and seep through the fabric.
Additional Support
Consider adding additional stakes or a center ridge pole to provide extra support and keep the tarp taut. This will help prevent the tarp from sagging or flapping in the wind.
