VAN-COMPARATOR Guide
Heatwave: where to go by campervan when it hits 40°C
When southern Europe tops 40°C, two campervan strategies work: gain altitude or head for the north Atlantic. Concrete destinations and anti-heat tactics.
A campervan is a metal box: parked in the sun at 40°C, the interior becomes unlivable by 10 am. Cab air conditioning only works while driving, and few rental vehicles carry a roof AC unit. The real solution isn't technical — it's geographical.
Strategy 1: gain 1,500 m of altitude
You lose roughly 1°C every 150 m: at 1,500 m, a 40°C lowland scorcher becomes a dry 30°C, and nights drop back below 18°C — the threshold for sleeping properly in a van. Proven picks: the Alps from Geneva, Innsbruck or Salzburg, the Dolomites, the Pyrenees, or Switzerland's Engadine, where even August stays cool.
Strategy 2: aim for the north Atlantic
Brittany, Normandy, Ireland from Dublin, Scotland from Edinburgh, or Scandinavia: during a continental heatwave, these coasts often top out at 22–26°C. Bonus: it's where the van fleet is best suited (heating, insulation), and heat spells there rarely last more than two or three days.
Last-minute booking: doable
Contrary to expectations, vans are still available a week out in mid-summer in mountain and northern cities — it's the south that sells out. On Van-Comparator, compare Yescapa, Goboony, Roadsurfer and Indie Campers across several departure cities at once to spot availability.
The moves that save the night
- Park in the afternoon shade (west side of a building or hedge), not the morning shade.
- Reflective screens on the windscreen and cab windows, cross-ventilation as soon as the sun sets.
- Drive during the hottest hours (AC), sightsee early and late, nap in the shade.
- Check how the fridge copes with heat: a compressor fridge holds up, an absorption three-way fridge struggles above 35°C.
And if the heat catches you mid-trip, remember a campervan's structural advantage: you can simply drive 300 km north or climb 1,000 m, and sleep cool that same night.
