As temperatures across the UK are forecast to hit a sweltering 40°C this week, many travellers are rethinking their summer holiday plans. Instead of chasing even hotter destinations in southern Europe, a growing number of holidaymakers are opting for the latest travel trend: the coolcation.
The term refers to travellers seeking out destinations with milder climates, offering a more comfortable and enjoyable holiday experience during extreme summer heat. This year, cities across Northern Europe are becoming increasingly popular alternatives to traditional Mediterranean hotspots.
If you’re looking for a last-minute escape from the heat, these three European city breaks could be the perfect solution.
Why Coolcations Are Trending in 2026
For years, summer holidays were all about sunshine and soaring temperatures. However, with heatwaves becoming more frequent across Europe, many travellers are prioritising comfort, walkability and outdoor experiences without the risk of extreme heat.
According to forecasts, cities such as Dublin, Copenhagen and Stockholm are expected to remain significantly cooler than many parts of the UK this week, making them ideal destinations for a summer getaway.
Dublin: Ireland’s Refreshingly Cool Capital
Dublin is one of the easiest and most accessible city breaks for UK travellers. With forecast highs around 27°C, Ireland’s capital is expected to be up to 11°C cooler than some parts of Britain.
The city’s compact centre makes it ideal for exploring on foot, while attractions such as the historic waterfront, riverside walks and nearby coastal towns provide plenty of opportunities to stay comfortable during warmer days.
Travellers looking for affordable accommodation can stay at Generator Dublin, which offers a central location within walking distance of many of Dublin’s top attractions.

Copenhagen: Scandinavian Style Without the Scorching Heat
Copenhagen continues to rank among Europe’s most liveable cities, and it’s easy to see why.
With temperatures expected to remain comfortably in the low-to-mid 20s, the Danish capital offers visitors a pleasant summer climate alongside world-class design, vibrant waterfront neighbourhoods and extensive cycling routes.
One of Copenhagen’s standout features during summer is its harbour baths, where locals and visitors alike can cool off in the city’s clean waterways.
Accommodation is available at Generator Copenhagen, which provides a convenient base for exploring the city.

The city’s abundance of green spaces, waterfront promenades and open-air attractions make it a popular destination for travellers seeking a more relaxed alternative to crowded southern European resorts.
For accommodation, Generator Stockholm offers a central location with easy access to the city’s major districts and island-hopping opportunities.

Could Coolcations Become the New Summer Holiday?
As climate patterns continue to change, travel habits are evolving alongside them. More holidaymakers are choosing destinations based on comfort, outdoor accessibility and quality experiences rather than simply seeking the hottest weather possible.
With Dublin, Copenhagen and Stockholm all forecast to remain noticeably cooler than many parts of the UK this week, the coolcation trend shows no sign of slowing down.
For travellers seeking a refreshing summer escape, Northern Europe may be the hottest travel trend of all—without the heat.
