If you’re planning van life in Europe in summer without air conditioning, this answers the question that comes up every year. How do you handle the heat, especially with dogs? After four years of full-time van life, including one very sweaty first summer where we got it completely wrong, this is what’s worked for us
TL;DR
- The most effective strategy for summer van life in Europe is moving to a higher altitude. Gain 1,000 metres, and you drop roughly 10 to 15 degrees Celsius.
- We spend summers in the Alps and avoid southern Europe and low-altitude areas from June to September.
- We don’t leave our dogs in the van during hot weather, ever, and we plan every summer day around it.
- Nights are harder than days. A van that reached 36°C in the day can sit at 25°C or above at night.
We have no fans, no roof vent, and no AC.
How we survive van life in Europe in summer without AC
Short answer: we don’t really survive it; we just don’t put ourselves in it anymore.
Year one of van life in Europe taught us everything about summer heat the hard way. We spent a stretch of that summer at low altitude, somewhere in the 35 to 36°C range, and we tried everything people suggest online. Fans, shade, keeping water on us, timing our walks with the dogs to early morning. None of it made a real dent. We were uncomfortable, Summer and Shadow were uncomfortable, and the nights were somehow worse than the days because the van never cooled down properly. We had nights where it was still 25°C inside at midnight, and mosquitoes on top of it.
We’ve also learned to cook outside during summer evenings rather than inside the van. A gas burner inside on a hot night is its own kind of miserable.
That experience changed how we plan our lives on the road. We’re not trying to manage the heat anymore. We just go where there isn’t any. Summers in the Alps, winters further south. The Dolomites in particular are one of our go-to destinations for summer van life – I have a full guide to exploring the Dolomites by campervan if you want more details.
The biggest misconception about van life in summer
Most people think they need a better setup: a bigger fan, more insulation, more solar, maybe a portable cooler. And look, if you have AC and the power system to run it, then yes, gear solves it. But not every van setup can support AC, and even fewer people have budgeted for it when they start out. So the conversation becomes: which gadgets will fix this?
The honest answer is none of them, not if you’re in the wrong place.
Insulation slows the heat down; it doesn’t stop it. A van sitting in direct sunlight on a 30°C day will get hot inside, no matter what’s in the walls. Fans move air around, which helps at moderate temperatures, but above 30°C, you’re mostly just moving hot air from one side of the van to the other.
The thing that works is moving 1,000 metres higher. Do that, and you drop 10 to 15°C. The fridge starts running properly again, the dogs settle, and you can sleep again.
What our daily summer routine looks like
Even in the Alps, it still gets warm, especially in July. This is what a typical summer day looks like for us:
We start work early, usually around 6 am, and get through everything important before the heat builds. Around 2 pm, depending on where we’ve parked, the van starts heating up noticeably, and that’s our cue to leave. We’ll head to a shaded climbing crag or find water, and that becomes our afternoon.
We park with intention. Not just for the shade that’s available when we arrive, but for where the sun will be in three hours. It’s a habit that took time to build but makes a real difference.
We use window covers to block direct sunlight and keep airflow moving when there’s a breeze. We cool ourselves and the dogs down physically: cold dips, swimming, wetting them down when needed. I also make frozen treats for Summer and Shadow, things like frozen watermelon, strawberries, stuffed Kongs. It keeps them occupied and cooled down at the same time.
We plan our work and activities around the hours when the van will be uncomfortable.
Leaving dogs in the van in the summer
We don’t leave our dogs in the van in hot weather. Full stop.
Even in the mountains, even in shade, even with windows cracked. Shade moves. Weather changes. Vans heat up faster than you expect and cool down slower than you’d like.
If we need to go somewhere where dogs aren’t allowed, we plan it around cool hours: early morning or late evening.
It does limit what we can do, and that’s just the reality of travelling with dogs. A few weeks ago, in April, we had a sudden heatwave, temperatures hitting 30°C, and we desperately wanted to do a via ferrata, but obviously couldn’t take the dogs. So we set the alarm for 6 am, walked them, climbed it, and were back at the van before 10.
The small things that help
These don’t replace location, but they do make a difference:
- Parking in the shade and thinking about where the sun will be later rather than just where it is now.
- Window covers on every window to block direct sunlight.
- Opening the van fully in cool morning air and then closing it up before the heat rises, to trap the cooler air.
- Starting work early and finishing before peak heat.
- Cold showers or a quick river dip to bring body temperature down.
- Wetting the dogs when they’re getting too warm.
- Cooking outside instead of heating up the van with a stove.
You’ll see people using reflective foil on windows, roof fans, and portable evaporative coolers. All of those things genuinely help at moderate temperatures. None of them replaces the fundamental decision about where you park yourself.
If you are thinking through the broader practicalities of van life in Europe – security, where to park, what to do in cities- I have a separate guide covering van life safety in Europe that goes into all of it.
Where to go in Europe for van life in summer
For us, the Alps are the answer. Northern Italy, France. Higher altitude, cooler air, easy access to lakes and rivers. You’ll still get hot days, but they’re manageable, as the nights are genuinely cold.
The Dolomites in July are spectacular and sit high enough to be bearable. We’ve covered van life parking in the Dolomites in detail if you want specific spots.
Coastal areas in southern Europe are harder in peak summer unless you’re right by the water with a reliable sea breeze. The Spanish and Italian coasts can be beautiful, but they can also be 38°C with no shade and nowhere to park in the shade.
Scotland and Scandinavia are the other options if you want cool summers with guaranteed relief. The Scottish Highlands in July rarely break 20°C and are beautiful.

Best European countries for summer van life
Temperature, dog-friendliness and honest verdicts – by month
| Destination | Best months | Day temp | Dog-friendliness | Van life verdict |
|---|---|---|---|---|
| Norway Bergen / fjords |
June – Aug | 17 – 20°C | ★★★★★Wild camping legal | Cool, green, uncrowded. Allemannsretten law means dogs welcome almost everywhere. Beaches unrestricted. Ideal if heat is your enemy. |
| Northern Norway Tromsø / Lofoten |
June – July | 13 – 16°C | ★★★★★Wild camping legal | Cooler but magical. Midnight sun in June – July. Almost no other vans. Worth the drive north. |
| Scotland | June – Aug | 17 – 19°C | ★★★★★Right to roam law | Midges in July/Aug. Bring a head net. Otherwise excellent. Free wild camping. Dogs on almost all land. |
| French Atlantic coast Biarritz area |
June, Sept | 22 – 25°C | ★★★Beaches: off-season only | Warm but not brutal. Surf culture, good campsites, dog-friendly off-season. Busy July – Aug, so avoid peak weeks. |
| Alps Austria / Switzerland / N Italy |
July – Aug | 24 – 25°C | ★★★★★Some sky lifts: no dogs | Perfect summer temps. Altitude keeps it cool even in heat waves. Mountain trails mostly dog-friendly. Note that some sky lifts will not allow dogs. Expensive. |
| Portugal Lisbon coast / Alentejo |
Avoid June – Sept | 23 – 29°C | ★★Beach bans and brutal heat | Too hot, too restricted. We have done this in summer and it is not worth it. 28 – 29°C in a van with no AC is not manageable. Most beaches ban dogs June – September. Visit in May or October instead. |
| Croatia Dalmatian coast |
Avoid June – Sept | 23 – 31°C | ★★Dogs banned: most beaches | Overcrowded and dog-unfriendly. July – Aug hits 31°C and the coast is packed. Dogs banned from most beaches all summer. Shoulder season is the only sensible window. |
| Southern Italy / Spain Rome, Seville |
Avoid June – Sept | 31 – 36°C | ★★Beach bans and dangerous heat | Not viable for dogs in a van. Heat dangerous for animals without shade or AC. Most beaches ban dogs June – September. Save it for spring or autumn. |
Dog-friendliness ratings are based on national rules, not campsite policies. Norway’s Allemannsretten and Scotland’s Land Reform Act both explicitly cover dogs on leads across most land. Portugal, Croatia, and southern Europe largely ban dogs from beaches June – September. Combined with extreme heat in a van, this makes summer a poor window for travelling with dogs across the whole Mediterranean region.

FAQ
Can you live in a van without AC in summer?
Yes, but only if you’re willing to move with the season. The Alps, Pyrenees, Dolomites, Scottish Highlands, and Scandinavian countries all offer genuinely comfortable summer temperatures at altitude or latitude. If you stay in southern Europe at low altitude through July and August, it becomes very difficult to manage without AC.
How do you keep a van cool without air conditioning?
You don’t really cool a van so much as stop it from overheating, and then build your day around the hours when it won’t. That means parking in shade and thinking ahead about the sun’s movement, using window covers, opening everything in the cool of the morning and closing up before the heat peaks, and not being inside during the middle of the day. The single most effective thing is location: a 1,000 metre gain in altitude drops you 10 to 15°C.
What temperature is too hot for van life?
It depends more on wind and humidity than on the number alone. We’ve had 25°C days in the Alps with a cool breeze coming off the mountains, where the van was completely fine, and we were sleeping well. We’ve also had 25°C days at low altitude, still air, no shade, and it was genuinely uncomfortable. So there’s no clean threshold.
That said, as a rough guide: once it’s consistently above 28 to 30°C with little wind and you’re at low altitude, you’re managing rather than living. Inside a van in direct sunlight, the temperature is always higher than outside, so that ambient temperature matters less than what’s happening around where you’re parked. Wind, shade, and altitude together are what determine whether a given temperature is livable.
How hot does a van get in summer?
More than you’d expect, and faster than you’d expect. In direct sunlight on a hot day, the interior gets significantly hotter than the air outside, and it holds that heat for a long time after the sun moves. With window covers, shade parking, and airflow, you keep it much lower, but there’s no getting the inside meaningfully below ambient temperature without AC. That’s really the point: you’re not cooling the van, you’re just slowing how fast it heats up.
How do you sleep in a van in the summer heat?
This is genuinely the hardest part. Park somewhere with natural airflow rather than a sheltered hollow, open everything you safely can, sleep with minimal bedding, and if possible, get yourself to an altitude where nights drop below 18°C. In a heatwave at a lower altitude, a van doesn’t cool down properly overnight because the metal holds the heat. That’s the situation we were in during our first summer, with nights sitting above 25°C, and the honest answer is: move, or you won’t sleep.
Do fans actually work in a van?
They help up to a point. A fan makes things noticeably more comfortable when temperatures are moderate. Above 32 to 35°C, it mostly just moves hot air around. A good roof vent fan does a better job than a standard fan because it actively pulls air through rather than just circulating it, but it still won’t save you in a genuine heatwave.
Is it safe to leave dogs in a van in summer?
No, not in hot weather. Even in shade, even in the mountains, even with the windows open. Temperature in a parked van can rise faster than you’d expect, and shade moves as the sun tracks. We don’t leave Summer and Shadow in the van if it’s above around 18°C outside and we’re not close by to check regularly. It does limit what you can do in summer, and that’s just the reality of travelling with dogs.
How do you keep dogs cool in a van in summer?
Prevention rather than cooling after the fact. We stay in cooler locations, park in shade, keep fresh water available all the time, and cool them down directly when needed: a swim, a river dip, or simply wetting them. I also make frozen treats, frozen watermelon slices, stuffed Kongs kept in the freezer, and strawberries. It keeps them cool and occupied.
Do you need AC for van life with dogs in Europe?
It depends entirely on how you travel. If you plan to spend time in cities, stay at a low altitude in summer, or regularly leave your dogs in the van during the day, AC is important. If you’re moving with the seasons, spending summers at altitude, and adjusting your daily routine around your dogs’ needs, it’s possible without it. We’ve done four years without AC, and it works, but we’ve also built our entire summer itinerary around staying somewhere cool.
What are the best places for van life in Europe in summer?
The Alps are our first choice: Austria, northern Italy around the Dolomites, and Switzerland. You get altitude, cooler air, and stunning landscapes. The Pyrenees are excellent and less busy. Scotland is genuinely cool in summer, and the Highlands are extraordinary. Scandinavia, if you want to go further north. Southern France, Spain, and Italy in July and August require a coastal position with a sea breeze, or you’re in a heat trap.
Does cooking in the van make it hotter?
Considerably. We cook outside in summer whenever we can, or stick to things that don’t need heat during the hottest part of the day. A gas burner or induction stove inside a closed van on a 30°C day adds noticeably to the heat inside. Cold meals in summer, hot meals outside in the evening.
