Quick Answer
Using a tarp over a tent in rain can provide extra protection against heavy downpours and wind-driven rain, but it's not always necessary in light to moderate rain. A well-ventilated tent can still keep you dry in such conditions. However, in heavy rain, a tarp can make a significant difference.
Why Use a Tarp Over a Tent?
A tarp can be an excellent addition to your shelter setup, especially in harsh weather conditions. When set up correctly, a tarp can channel rainwater away from your tent, preventing it from seeping in through the fabric. This is particularly useful in areas with high winds or heavy rain, where a tarp can help reduce the pressure on your tent’s seams.
Choosing the Right Tarp Setup
The key to a successful tarp setup is to create a slope that allows rainwater to run off. This can be achieved by attaching the tarp to trees or poles at a 30-40 degree angle. The tarp should be tight and evenly spaced to prevent it from flapping in the wind. A good rule of thumb is to use a tarp that’s at least 10 feet by 10 feet in size, which provides ample coverage and can be set up in a variety of configurations.
Tarp Setup Techniques
When setting up a tarp over a tent, it’s essential to secure it tightly to the surrounding structures. This can be done using rope, cordage, or even clips. A tarp clip or tarp stake can be used to attach the tarp to the ground, while a ridge line can be used to connect the tarp to the uppermost point of your shelter setup. By using these techniques, you can create a robust and water-resistant shelter setup that’s perfect for harsh weather conditions.
