Summer camping is all about sunshine, campfires, lakeside afternoons, and making memories with the people you love. But when a heat wave rolls in, even the best adventures can get a little… toasty.
The good news? A little planning goes a long way. Whether you’re heading out for a weekend getaway or a cross-country road trip, there are plenty of simple ways to keep your RV comfortable and enjoy your adventure, even during extreme summer temperatures.
Here are some of our favourite tips for staying cool while camping during summer heat waves.
1. Start Keeping Cool Before You Leave Home
The best way to beat the heat is to plan ahead before you even pull out of the driveway.
A few simple steps can make a big difference once you arrive at your campsite:
- Check and replace your RV’s air conditioner filter if needed.
- Pre-cool your RV before loading up and hitting the road.
- Freeze a few bottles of water to keep your cooler colder for longer—and enjoy ice-cold drinks later in the day.
- Pack cooling towels, refillable water bottles, portable fans, and plenty of sunscreen.
Starting your trip prepared means you’ll spend less time trying to cool down and more time enjoying your camping adventure.
2. Choose Your Campsite Wisely
Where you park can have a surprising impact on how comfortable your RV stays throughout the day.
If you have the option, look for campsites with afternoon shade. Trees can naturally reduce the amount of direct sunlight hitting your RV, helping keep interior temperatures lower.
Once you’re set up, extend your awning whenever possible to create additional shade outside. Not only does it help reduce heat entering your RV, but it also creates a comfortable outdoor living space where you can relax during the day.
3. Keep the Heat Outside
When temperatures climb, every little bit of shade helps.
Closing your blinds or curtains during the hottest parts of the day blocks direct sunlight from heating up your RV’s interior. Reflective window coverings can also make a noticeable difference, especially on windows facing the afternoon sun.
Try to keep exterior doors closed as much as possible to prevent hot air from rushing inside, and whenever you can, move your cooking outdoors. Using your barbecue, griddle, or camp stove instead of the indoor oven helps keep unwanted heat out of your living space while making the most of the beautiful weather.
4. Help Your Air Conditioner Work Smarter
Your RV’s air conditioner works hard during a heat wave, but it’s important to remember that even the best systems have their limits.
Most RV air conditioners are designed to cool the inside of your RV approximately 16–22°F (9–12°C) below the outside temperature. On exceptionally hot days, your AC may run continuously simply because it’s doing exactly what it was designed to do.
You can help your system perform at its best by:
- Keeping air vents clear and unobstructed.
- Using portable or ceiling fans to circulate cool air more efficiently.
- Closing windows while the air conditioner is running.
- Parking in the shade whenever possible.
Working with your air conditioner instead of expecting it to do all the work will help keep your RV as comfortable as possible.
5. Plan Your Day Around the Heat
One of the best parts of camping is spending time outdoors, but during a heat wave, timing matters.
Plan hikes, bike rides, and other active adventures during the cooler morning or evening hours. Save the hottest part of the afternoon for swimming, relaxing under the awning, reading a good book, or exploring a nearby town or attraction.
And don’t forget to stay hydrated. Drink water throughout the day, even if you don’t feel thirsty, and keep an extra eye on children, older adults, and pets, who can be more sensitive to extreme temperatures.
6. Let Fresh Air Work for You
When temperatures begin to cool in the evening or early morning, take advantage of the natural breeze.
Opening windows and roof vents creates cross ventilation that helps flush out built-up heat from inside your RV. Combined with a portable fan, even a gentle breeze can make your space feel significantly cooler before another warm day begins.
Don’t Let the Forecast Stop the Adventure
A summer heat wave doesn’t have to put your camping plans on hold. With a little preparation, smart campsite setup, and a few simple cooling strategies, you can stay comfortable while making the most of everything the season has to offer.
