Summer is one of the best times to own an RV in Washington State. Long days, mountain views, lakes, beaches, forests, and seemingly endless road-trip possibilities make it easy to understand why campgrounds fill up once warm weather arrives.

But summer RV camping in Washington isn't always as cool as the Pacific Northwest's reputation suggests.

Western Washington can experience surprisingly hot stretches, while destinations east of the Cascades—such as Lake Chelan, Wenatchee, Yakima, and Spokane—regularly bring hotter, drier summer conditions. Even a comfortable day outside can turn an RV into a warm space when it's parked directly in the afternoon sun.

Inspired by recent summer camping advice from Keystone RV, we've put together a Washington-focused guide for Tacoma RV Center customers. Keystone's campers emphasize strategies such as considering sun exposure when choosing a campsite, spending more time outdoors, staying hydrated, maintaining good airflow, and giving your RV's air conditioner some help rather than expecting it to battle the heat alone.

Whether you're planning a weekend near Tacoma or a week at Lake Chelan, these summer RV camping tips can help make your next Washington adventure more comfortable.

1. Think About the Sun Before You Set Up Your RV

You've arrived at the campground.

Before immediately unhitching, leveling, and extending the slides, take a look around your campsite.

Where will the afternoon sun hit your RV?

A campsite that feels comfortable at 10 a.m. can look completely different at 4 p.m. If the largest windows on your RV spend the hottest part of the day facing direct sunlight, your air conditioner may have to work significantly harder.

When your campsite and campground rules allow, consider how the RV's orientation, existing trees, and your awning can help provide shade. Keystone's summer camping advice similarly recommends thinking about afternoon sun exposure and closing shades before the interior becomes hot.

You can't always choose your RV's orientation, especially in established campgrounds, but you can use:

• Window shades

• Reflective window coverings when appropriate

• Awnings

• Natural shade

• Outdoor shelters

• Proper ventilation

The key is getting ahead of the heat instead of waiting until the interior is already uncomfortable.

2. Make Your Campsite an Outdoor Living Room

One of the best features of RV camping is that your campsite effectively becomes an extension of your RV.

Instead of keeping everyone inside all afternoon, create an outdoor living area beneath your awning.

Bring out the chairs, outdoor rug, table, games, and maybe a portable fan.

This gives everyone more room while reducing how often the RV door is opened and closed.

It also helps you enjoy the reason you went camping in the first place:

being outside.

Keystone's campers recommend moving more of camp life outdoors during warm weather and using the awning as additional living space.

For Washington campers, this can be especially enjoyable when you're parked beside a lake, overlooking the mountains, or only steps from the Pacific Ocean.

Sometimes the best summer camping memories aren't on the itinerary at all—our guide to slowing down and enjoying the RV journey explains why an afternoon beneath the awning can be just as memorable as the destination itself.

3. Cook Outside When Temperatures Climb

Your RV kitchen is incredibly convenient.

On a hot afternoon, however, your stove and oven can add unwanted heat to the interior.

Summer is the perfect excuse to move dinner outside.

Depending on your setup and campground rules, consider using an RV outdoor kitchen, griddle, or grill. Keystone's campers specifically note that cooking outdoors helps keep additional heat and food odors outside the RV.

Outdoor cooking can also become part of the camping experience instead of simply another chore.

Think:

• Breakfast outside in the morning

• Burgers after a day at the lake

• Grilled vegetables

• Campground tacos

• Hot dogs

• Foil-packet meals

• Campfire desserts when fires are permitted

If you're shopping for an RV and love summer camping, an outdoor kitchen may be worth adding to your floorplan wish list.

4. Stay Ahead of Hydration

It's easy to think about hydration when you're hiking.

It's easier to forget about it when you're simply setting up camp.

But parking, leveling, unhitching, extending stabilizers, connecting utilities, carrying equipment, walking around the campground, and setting up outdoor furniture can quickly become strenuous on a hot day.

Don't wait until you're thirsty.

Keep water easily accessible while traveling and after arriving at camp. Keystone's summer camping advice recommends keeping reusable water bottles nearby throughout the day rather than waiting until dehydration becomes noticeable.

This becomes especially important when camping in hotter parts of Washington.

A July trip to Eastern Washington can feel dramatically different from camping near the coast.

5. Don't Forget About Your Pets

Your four-legged camping companions feel the summer heat too.

Make sure pets have access to:

• Fresh water

• Shade

• A comfortable RV interior

• Breaks during activities

• Safe places away from hot pavement

Keystone also cautions summer campers to consider pets' hydration, shade, and exposure to hot surfaces.

Never assume that because you're comfortable, your pet is comfortable.

And be especially careful about leaving pets alone inside an RV during hot weather. If campground power fails or the air conditioner stops working, interior temperatures can rise.

6. Help Your RV Air Conditioner Work Smarter

Your RV's air conditioner may be powerful, but it doesn't need to fight the summer heat alone.

A few simple habits can help reduce the heat entering your RV.

Close blinds and shades before direct sunlight begins heating the interior.

Limit unnecessary opening and closing of exterior doors.

Use vents and fans strategically when outside temperatures become cooler than the interior.

And don't overlook your air-conditioning system itself.

Keystone recommends checking return vents and filters and keeping them clean to support proper airflow, while following the maintenance instructions for your particular air-conditioning system.

If your RV air conditioner doesn't seem to be cooling properly, don't automatically assume that's simply how RV air conditioning works.

A system that isn't performing normally may need attention.

7. Get Your RV Serviced Before the Hottest Trip of the Year

The campground is not where you want to discover that something isn't working correctly.

Before a major summer trip, inspect the systems you'll rely on most.

Consider checking:

• Air conditioning

• Batteries

• Electrical connections

• Tires

• Wheel bearings

• Brakes

• Roof seals

• Plumbing

• Refrigerator

• Water system

• Propane system

• Exterior lights

Tacoma RV Center's summer maintenance guide emphasizes preventative checks during Washington's peak camping season, including tires, bearings, batteries, air-conditioning performance, and roof seals.

8. Choose Summer Campgrounds With the Right Amenities

A beautiful campsite matters.

So do amenities.

When temperatures rise, a campground with access to water can completely change your afternoon.

Depending on your camping style, look for destinations with:

• Swimming pools

• Lakes

• Rivers

• Beaches

• Shaded picnic areas

• Full hookups

• 30- or 50-amp electrical service

• Trees and natural shade

Keystone's summer camping article specifically recommends considering amenities such as campground pools when planning trips during particularly hot weather.

In Washington, you have plenty of alternatives to a traditional pool.

Lake Chelan, Hood Canal, Puget Sound, and numerous mountain lakes provide opportunities to build an RV trip around the water.

9. Try Washington Beach Camping for a Cooler Summer Escape

Not everyone wants 90-degree camping weather.

If your idea of a perfect summer involves hoodies around the campfire rather than hiding from the afternoon sun, point your RV toward the Pacific.

Ocean Shores, Long Beach, Cape Disappointment, and the Olympic Peninsula can provide a dramatically different summer camping experience than Eastern Washington.

Washington's coastline combines beaches, sunsets, hiking, tide pools, small coastal towns, and cool Pacific air.

Just remember: coastal camping introduces its own RV considerations.

Weather can change quickly, and salty coastal air makes regular RV maintenance important.

10. Plan Ahead—but Watch for Cancellations

Summer campground reservations in Washington can be competitive.

Waterfront sites, full hookups, and popular weekend dates often disappear well ahead of the trip.

Tacoma RV's campground reservation guide notes that Washington State Parks allows reservations up to nine months ahead and recommends checking cancellation availability when preferred campgrounds are already full.

So if you're planning a summer trip:

Book early when you can.

But don't give up when you can't.

Check:

• Weekday availability

• Cancellation openings

• Nearby campgrounds

• Private RV parks

• Less-popular loops

• Alternative destinations

Flexibility can turn a "sold out" weekend into one of your favorite trips.

Summer campsites can disappear quickly, so use our Washington State Park reservation guide to learn when to book, how to find cancellations, and what to do when your first-choice campground is full.

11. Keep Campfire Restrictions in Mind

A summer evening around the campfire is a classic part of camping.

But during dry Washington summers, campfire restrictions can change quickly.

Never assume a fire is allowed simply because your campsite has a fire ring.

Check current campground and local restrictions before lighting anything, and follow all posted rules.

When fires are permitted, keep water nearby, never leave the fire unattended, and make sure it is completely extinguished before leaving the campsite or going to bed.

Before lighting your first summer campfire, review our Washington RV campfire safety guide for tips on enjoying the tradition while helping protect the places we love to camp.

Tacoma RV Center published its Washington-focused campfire safety guide in August 2026.

12. Prepare for Washington Weather to Change

One of the strangest things about summer RV camping in Washington?

You can pack for heat and still need a sweatshirt.

A trip around the state might take you from a hot afternoon east of the Cascades to a cool coastal evening within a matter of days.

Even Western Washington summer trips can bring occasional rain. Tacoma RV's Puget Sound campground guide recommends bringing waterproof gear and preparing for changing conditions even during the June-to-September camping season.

Pack layers.

Bring rain gear.

Keep a few indoor activities available.

And don't let an imperfect forecast ruin the trip.

That's one of the biggest advantages of RV camping—you brought shelter with you.

13. Don't Try to Pack Every Day With Activities

You're at Lake Chelan.

You need to swim, hike, kayak, visit town, explore wineries, watch the sunset, make dinner, play games, and somehow relax.

Right?

Not necessarily.

One of Keystone's most important summer camping suggestions is also one of the simplest: slow down. Some of their favorite memories came from ordinary campground moments rather than a packed activity schedule.

Leave some blank space in the itinerary.

Sit under the awning.

Play cards.

Read a book.

Watch the campground.

Make ice cream.

Take a nap.

Stay outside until the stars come out.

You don't need to maximize every hour to make a camping trip worthwhile.

If your summer vacation itinerary is starting to look more like a checklist, read our guide to slowing down and enjoying the RV journey—because sometimes doing less creates the memories you remember most.

14. Don't Ignore Your RV Roof During Summer

Washington RV owners often associate roof leaks with fall and winter rain.

But summer creates its own challenges.

Heat and UV exposure can affect exterior materials and sealants, while summer travel exposes your RV to tree branches, road vibration, and changing temperatures.

Inspecting your roof and exterior seals throughout camping season can help you spot potential issues before fall rain returns.

Summer is a great time to inspect your RV before Washington's wetter months return—learn the warning signs of an RV roof leak and what to look for before small problems become bigger repairs.

15. Keep a Few Summer Essentials Ready to Go

Creating a dedicated summer camping kit can make spontaneous weekends much easier.

Consider keeping commonly used items together, such as sunscreen, insect repellent, refillable water bottles, flashlights, outdoor games, portable fans, hats, basic first-aid supplies, rain gear, and extra charging cables.

If you regularly camp with pets, keep their supplies organized too.

The less time you spend packing, the easier it becomes to say:

"The weather looks great this weekend. Let's go camping."

And that spontaneity is one of the best parts of owning an RV.

A memorable summer RV trip doesn't require driving across Washington.

Make the Most of Summer RV Camping in Washington

Summer doesn't last forever in the Pacific Northwest.

So use it.

Take the Friday afternoon trip.

Book the campground by the lake.

Head toward the coast when temperatures climb.

Cook dinner outside.

Sit beneath the awning.

Stay hydrated.

Keep the RV maintained.

And don't feel like every minute of the trip needs to be planned.

Keystone's summer camping advice comes down to working with the heat rather than fighting it: choose your campsite wisely, spend more time outside, stay hydrated, support your RV's cooling system, and make time to simply enjoy being at camp.

That's especially good advice here in Washington, where one RV can take you from Puget Sound to the Cascades, the Pacific Coast, the Olympic Peninsula, or the sunny side of the state.

Your RV gets you there.

What you do once you arrive is up to you.
