Camping in the Rain: How to Stay Dry in Your Roof Top Tent

Rain doesn't have to mean the end of a camping trip. In fact, some of the most memorable adventures happen when the weather turns—the sound of rain on canvas, the fresh smell of the bush after a downpour, and the sense of accomplishment from weathering the storm. The key is knowing how to stay comfortable when the skies open up.

This guide covers everything from preparing your tent for wet weather to managing condensation and staying dry when you need to venture outside. Master these techniques, and you'll transform rainy days from trip-enders into just another part of the adventure.

Understanding How RTTs Handle Rain

Roof top tents have inherent advantages in wet weather compared to ground tents. Being elevated keeps you above pooling water and mud, and the sturdy construction of most RTTs handles rain better than lightweight backpacking tents. However, they're not immune to water intrusion if you don't set up correctly.

Common Wet Weather Weak Points

• Door openings: Rain can be driven inside through partially open doors, especially with wind
• Window mesh: If rainfly coverage is inadequate, mesh panels can allow water spray
• Seams: Older or poorly maintained tents may have compromised seam sealing
• Ladder opening: The entry point where the ladder connects is vulnerable
• Zippers: Water can track along zipper teeth if not properly sealed

Pre-Trip Preparation

The best defence against wet weather starts before you leave home.

Test Your Waterproofing

Set up your tent in the backyard and spray it with a garden hose. Observe where water penetrates or pools. Pay attention to:

• Seam integrity—look for any water seeping through stitching
• Canvas condition—water should bead and roll off, not soak in
• Rainfly coverage—ensure it adequately covers all openings
• Zipper function—they should close completely without gaps

Pack for Wet Weather

Even if the forecast looks clear, carry these items:

• Quick-dry towels (multiple)
• Waterproof bags for electronics and valuables
• Spare dry clothes in waterproof storage
• Rain jacket and waterproof pants
• Tarp or additional cover for creating dry outdoor space
• Umbrella (surprisingly useful around camp)

Setting Up in Wet Conditions

If rain catches you during setup, or you arrive at camp with storms approaching, follow these guidelines.

Site Selection

• Avoid low spots where water will collect
• Look for natural drainage—slight slopes can help
• Stay away from dry creek beds (flash flood risk)
• Consider tree cover—but watch for "widow makers" (dead branches)

Orientation

Position your tent so the main door faces away from the prevailing wind direction. This prevents rain from being driven directly into the opening. If you're unsure which way rain will come, observe:

• Cloud movement direction
• Wind direction (rain typically comes from the same direction)
• Local knowledge if available

Quick Setup Protocol

When rain is imminent or already falling:

1. Open the tent quickly but carefully—don't force anything
2. Immediately deploy the rainfly fully
3. Close all openings except your entry point
4. Get inside with essential items first
5. Adjust and fine-tune once sheltered

Managing Condensation

Condensation is often a bigger problem than actual rain leaks. When warm, moist air from your breathing meets cold tent surfaces, water forms. In severe cases, it can feel like it's raining inside the tent.

Ventilation Is Key

Counterintuitively, better airflow reduces condensation even in rain:

• Keep ventilation openings partially open, even in rain
• Use covered vents that allow airflow while blocking water
• Create cross-ventilation when possible
• Crack the door slightly if your rainfly provides adequate coverage

Anti-Condensation Strategies

• Place an anti-condensation mat under your mattress
• Avoid storing wet gear inside the tent
• Wipe down interior surfaces before bed if condensation has formed
• Keep sleeping bags and bedding away from tent walls
• Consider a small moisture absorber (silica gel or similar)

Staying Dry During Your Trip

Managing wetness is an ongoing process throughout rainy weather camping.

Entry and Exit Protocol

The biggest source of interior wetness is often bringing it in yourself:

1. Remove wet outer layers before climbing up
2. Keep a dedicated "wet gear" area at the ladder base
3. Use a towel to dry off before entering
4. Have a mat at the entry to catch water from feet
5. Store wet items in waterproof bags rather than loose in the tent

Cooking in the Rain

You'll still need to eat. Options for rainy cooking:

• Set up your awning for covered cooking space
• Use your vehicle's tailgate area if accessible
• Prepare simple meals that require minimal time in the rain
• Never cook inside the tent—this is dangerous and adds moisture

Drying Opportunities

Take advantage of any breaks in the rain:

• Open all tent doors and windows for ventilation
• Hang damp items to air out
• Wipe down surfaces that have accumulated moisture
• Shake water off the rainfly if it's pooling

After the Rain

What you do after rain stops is just as important as managing during rain.

Post-Rain Tent Care

1. Open everything for maximum airflow
2. Allow surfaces to dry before packing up
3. Wipe down excess water to speed drying
4. Shake or brush off any debris that stuck during rain
5. Check for any damage or issues that need attention

When to Call It

While camping through rain is rewarding, know your limits and your tent's limits:

• Severe storms with lightning: Consider sheltering in your vehicle
• Extreme wind combined with rain: RTTs can become dangerous in very high winds
• Flash flood warnings: Move to higher ground immediately
• Prolonged heavy rain with no dry break: Sometimes the wise choice is to relocate to covered accommodation

Rainy weather camping is a skill that improves with practice. Your first wet weather trip might be challenging, but by your fifth, you'll have routines that make it almost effortless. The reward is experiencing the Australian bush in all its moods—and there's something deeply satisfying about emerging from a stormy night warm and dry, ready for whatever the day brings.
