Europe was once home to the perfectly temperate summer holiday, but increasingly, rising temperatures are turning many of the continent’s favourite holiday destinations into places where a day seeing the sights feels more like a challenge than an experience. The summer of 2026 has been another reminder of that shift, with red heat warnings issued across Europe and extreme temperatures bringing the heat to everywhere from the UK to the southeastern corners of the continent. Wildfires have blazed in places like Spain and Greece, and anywhere with a bit of a breeze has come to feel like manna from heaven.
Fortunately, help is at hand in the form of the cool vacation or ‘coolcation’. And while some of these spots have experienced warmer-than-normal temperatures (35C? In Wales? Wales?!), there is still respite to be found. From breezy islands to crisp mountain valleys, these destinations offer the opportunity to enjoy Europe in August without feeling like you’ve been packed into the air fryer.
