How to Use a Tarp and Rainfly Together for Maximum Storm Protection

Quick Answer

To maximize storm protection, set up your tent with its rainfly fully secured, then pitch a tarp overhead as a second layer. This creates a dry entry zone and adds a buffer against heavy rain and wind.

When the forecast calls for heavy rain or wind, a single rainfly might not be enough. Adding a tarp over your tent creates a double-layer defense that keeps you drier and gives you a covered area to cook or store gear.

In this guide, we'll walk through how to set up a tarp and rainfly together for maximum storm protection. You'll learn the best practices for positioning, tensioning, and securing both layers to weather any storm.

Why Combine a Tarp and Rainfly?

A rainfly is your tent's first line of defense against rain, but it doesn't cover everything. The area right outside your tent door is exposed, and in a heavy storm, water can splash up under the fly. A tarp pitched overhead extends your dry zone and adds an extra layer of protection against wind-driven rain.

Using both also helps with condensation. The space between the tarp and rainfly allows air to flow, reducing moisture buildup inside your tent. This is especially helpful in humid conditions or when you're camping with a partner.

• Pitch the tarp high enough to allow airflow but low enough to block wind and rain.
• Angle the tarp so rain runs off away from your tent entrance.
• Use guy lines and stakes to secure the tarp against gusts.

Tent Rainfly vs Tarp: What's the Difference?

Your tent's rainfly is designed to fit your specific tent, covering the body and often the vestibule. It's shaped to shed wind and rain efficiently. A tarp, on the other hand, is a versatile, flat sheet that can be pitched in many configurations. It doesn't hug your tent, but it can be positioned to create a larger covered area.

The key difference is that a rainfly is integrated with your tent's structure, while a tarp is independent. This means a tarp can be set up to cover your tent, your gear, or even a cooking area. When used together, they complement each other: the rainfly keeps your tent dry, and the tarp extends your protection.

• Rainfly: form-fitting, protects the tent body, and is essential for wind and rain.
• Tarp: versatile, can be pitched in multiple ways, and provides extra coverage beyond the tent.
• Use both for storms that bring prolonged rain or high winds.

Choosing the Right Tarp for Storm Protection

Not all tarps are created equal. For storm protection, look for a tarp with reinforced corners, webbing loops, and a waterproof coating. A rectangular tarp is the most versatile for covering a tent, as you can adjust the pitch to match your tent's shape.

Consider the size of your tent. A tarp that's too small won't provide adequate coverage, while one that's too large can be unwieldy in the wind. A good rule of thumb is to choose a tarp that's at least as long as your tent and slightly wider. This gives you enough overhang to protect the entryway.

For backpacking, weight and packability matter. Look for a lightweight tarp that packs down small. The Lightweight Stuff Sack Set from Sea to Summit is great for organizing your tarp, stakes, and guy lines, keeping them separate from your tent and other gear.

• Reinforced corners and webbing loops add durability and multiple tie-out points.
• A rectangular shape offers the most flexibility for covering a tent.
• Choose a tarp size that covers your tent with extra overhang for the entry.

Step-by-Step: How to Set Up a Tarp Over Your Tent

Setting up a tarp over your tent is straightforward, but it requires attention to detail. Here's a step-by-step process to ensure maximum storm protection.

First, pitch your tent as you normally would, making sure the rainfly is fully secured and the guy lines are taut. This is your base layer. Next, identify the direction of the wind. You'll want to position the tarp so it blocks the prevailing wind and sheds rain away from your tent door.

Now, set up the tarp. Use trekking poles, a ridge line, or a tree to create a high point. The tarp should slope downward, directing water runoff away from your tent. Secure the corners with stakes and guy lines, adjusting the tension to prevent flapping. Leave a gap of at least a foot between the tarp and your rainfly to allow airflow.

Finally, check for any low spots where water could pool. Adjust the pitch to eliminate these. Your tarp should be taut, with no sagging areas. If you're expecting heavy rain, consider adding a drip line to divert water from the tarp's edge away from your tent.

• Always pitch your tent first, then set up the tarp.
• Orient the tarp to block wind and shed rain away from the entrance.
• Leave a gap for airflow to reduce condensation.
• Check for pooling water and adjust the tarp's tension.

Step-by-Step: Tarp and Rainfly Setup

1. Pitch your tent with rainfly fully secured: Set up your tent as you normally would, ensuring the rainfly is clipped and guyed out. This creates your primary shelter layer. Check that all guy lines are taut to prevent flapping and water entry.
2. Assess wind and weather direction: Look at the sky and feel the wind. You want to position the tarp to block the prevailing wind and direct rain away from your tent entrance. If you're unsure, pitch the tarp with the low side facing the wind to deflect gusts.
3. Set up the tarp overhead: Use a ridge line, trekking poles, or trees to create a high point. Angle the tarp so water runs off to the sides, not over your tent door. Aim for at least a foot of clearance between the tarp and your rainfly for airflow.
4. Secure and tension the tarp: Stake out all corners and use guy lines to tighten the tarp. Eliminate any sagging or low spots where water could pool. Check the tension after a few minutes—tarps can stretch and loosen.
5. Test for drips and adjust: Pour a little water on the tarp to see how it runs off. Adjust the pitch if necessary to keep water away from your tent. Make small adjustments now to avoid a wet night later.
