Top tips: Stay cool in a roof tent during hot summer nights
There is nothing quite like waking up to panoramic views from the top of your vehicle on a warm summer morning. But as the temperature climbs, camping in hot weather can present a unique challenge: turning your cosy elevated sanctuary into a sauna by bedtime. Because roof tents sit higher up off the ground, they catch breezes much better than traditional ground tents, if you know how to set them up properly.
Whether you’re embarking on a summer road trip or enjoying a warm weekend getaway, here is your ultimate guide to beating the heat and sleeping comfortably in your roof tent.
1. Master the art of cross-ventilation
Airflow is your single best line of defence against trapped heat and humidity.
Unzip all windows and doors: Open the main canvas flaps on all sides; you can leave them partially zipped up to keep some privacy.
Keep the midge net zipped: Keep fine mesh layers zipped tight. This lets the nighttime breeze circulate continuously through the tent while keeping midges, mosquitoes, and unwanted bugs firmly outside.
Open skylights: If your tent features built-in skylights, leave them open overnight to let rising body heat escape naturally.
Pro Tip: Unzip windows slightly more on the leeward side (the side facing away from the wind) and less on the windward side. This creates a natural chimney effect that pulls cooler air through the tent.
2. Park for maximum shade (and wind)
Where and how you park your vehicle plays a massive role in internal tent temperatures:
Chasing evening shade: If possible, pitch your vehicle where trees or structures block the harsh afternoon sun (roughly 2:00 PM to 6:00 PM). A hardshell or canvas body exposed to direct midday sun absorbs heat that radiates inward long into the evening.
Orient into the breeze: Check the wind direction before parking. Position the widest window or main door facing directly into the oncoming breeze to maximise air intake.
3. Deploy your side awning for roof shade
If you are parked in an open field with zero tree cover, use your vehicle accessories to create your own shade:
Extend your side awning or 270 awning alongside the vehicle.
Creating a shadow footprint right beside your rig lowers the ambient ground temperature around your ladder and vehicle doors, keeping the surrounding air noticeably cooler.
If you have an awning room, leave the windows open to maintain airflow while blocking direct sunlight from hitting the lower vehicle body.
4. Ditch the synthetic bedding
Your mattress and sleeping gear heavily impact how cool you feel overnight:
Switch to breathable cotton or linen: Ditch heavy synthetic sleeping bags or polyester duvet covers. Use lightweight 100% cotton sheets or a breathable linen blanket.
Add an anti-condensation mat: Anti-condensation mats beneath your mattress not only prevent dampness in winter, but they also promote airflow under the foam mattress during summer, preventing heat from getting trapped underneath your body.
5. Pre-cool the roof tent before bed
Don’t wait until you are ready to fall asleep at 10:00 PM to unzipping your doors and windows.
Open it up early: As soon as the sun starts to dip in the late afternoon, open all windows, doors, and skylights.
Flush out trapped daytime air: Allow the cooling evening air to flush out the hot air that built up inside the canvas shell during the hottest part of the day.
6. Roll back or remove dark rainflys
If your roof tent features a dark or black waterproof rainfly, it can absorb a massive amount of solar heat, creating a “greenhouse effect” between the fly and the main canvas body.
Boost breathability: Removing or rolling back the rainfly strips away that less breathable waterproof layer, allowing heat to escape directly through the more breathable tent body fabric.
Flush out heat: Without the rainfly blocking skylights, warm air, which naturally rises, can vent straight out into the night sky.
Note: Completely removing the rainfly might not be possible on all roof tent models (especially certain integrated hardshell setups). However, many designs allow you to easily unhook poles, roll the rainfly back, and secure it with the built-in toggles. This gives you maximum ventilation overnight while keeping the fly ready to flip back over in seconds if an unexpected shower rolls in!
7. Smart hacks for extra cooling
Want some extra help to stay cool?
USB powered camping fans: Hang a small rechargeable USB hook fan from your roof tent’s ceiling. Position it to blow directly over your sleeping space or point it toward an open window to actively draw cooler air inside.
Damp towel trick: Hang a slightly damp microfiber towel across an open bug net window. As the night breeze passes through the damp cloth, evaporative cooling drops the air temperature by a few degrees.
Ready for Your Summer Escapes?
Camping in hot weather doesn’t mean sacrificing a great night’s sleep. By combining smart parking, maxing out your tent’s mesh ventilation, and using shade-creating accessories like vehicle awnings, you can keep your elevated basecamp fresh, airy, and comfortable all summer long.
