With extreme heat warnings covering large parts of England and Wales this week, many people are discovering that the hardest part of a heatwave isn't the daytime temperatures - it's trying to sleep once the sun goes down.

While sunshine may be welcome during the day, warm overnight temperatures can make bedrooms uncomfortable long after sunset. Forecasters are warning of "tropical nights" in some urban areas, where temperatures remain above 20°C overnight, leaving homes with little chance to cool down.

For anyone craving a last-minute escape this weekend, there are still plenty of destinations across the UK where temperatures are expected to remain considerably lower.

Looking North For Cooler Nights

If escaping the heat is the priority, Scotland's Highlands and Islands are likely to be among the most appealing destinations this weekend.

Western parts of Scotland are expected to stay cooler than many areas further south, with both Tiree and Castlebay forecast to see temperatures of around 15°C on Saturday before dropping by just a degree overnight.* Tiree could even see some rain during the early hours, helping to keep conditions feeling fresh.

Elsewhere, locations such as Pitlochry, the Isle of Arran and Blairgowrie are set to experience overnight lows in the mid-teens, along with the chance of rain in some areas. For travellers used to restless nights in warmer conditions, that could make these destinations particularly attractive over the coming days.

The Hebrides are also expected to enjoy some of the UK's coolest temperatures this weekend. Interest in cooler northern destinations appears to be growing too, with Superbreak seeing an 18% increase in bookings across the north of England, led by strong demand for breaks in the Lake District.

Coastal Wales And The South West Could Offer Relief

Although weather warnings remain in place across much of Wales this week, not every destination is expected to experience the same overnight temperatures.

Along the Welsh coast, locations including Llandudno, St Davids and Fishguard are forecast to cool to around 15°C overnight this weekend, offering a noticeably different experience from some inland areas.

Further south, parts of Devon and Cornwall are also expected to remain relatively comfortable. Lynton in North Devon and St Just in Cornwall are forecast to see daytime highs of around 18°C, making them some of the cooler destinations in England this weekend.

Travellers looking to combine fresh sea air with a hotel stay can also find breaks in popular coastal towns such as Penzance and North Devon, where some properties offer swimming pools for an extra way to cool down.

You May Not Need To Travel Far

For those unable to head to Scotland or the far South West, there are still ways to escape the heat closer to home.

The UK's coastline often enjoys more stable temperatures than inland areas thanks to cooling sea breezes. During warm spells, that can make seaside destinations feel noticeably more comfortable, particularly during the evening and overnight.

And for those staying local, even a nearby hotel break could make a difference. Air-conditioned rooms, blackout curtains and modern hotel facilities can provide welcome relief when temperatures remain high overnight.

Many spa breaks also offer access to outdoor pools, cold plunge facilities and other cooling experiences, making them an increasingly attractive option for anyone looking to escape the heat for a day or two.
