UK Foreign Office's travel warnings for Spain, Turkey, Greece and Cyprus

The Foreign Office has issued travel advice for Brits heading to Spain, Turkey, Greece and Cyprus as a heatwave sweeps across the European Union.

Northern Europe is currently enduring an early summer heatwave, with forecasters warning of soaring temperatures in the weeks to come. Here in the UK, we've also been feeling the heat, with thermometers hitting 34C on Saturday.

France's national weather agency, Meteo France, has echoed these warnings, cautioning that the high temperatures put "everyone at risk, even healthy people."

Portugal recently recorded its highest temperature this year at 40.5 degrees, while parts of Spain have seen the mercury rise above 42 degrees.

The situation is already much more serious in Southern Europe, with Chios in Greece in the grips of a fearsome wildfire at the moment. Locals have been evacuated after the tinder-dry island burst into flames over the weekend.

On its website, the Foreign and Commonwealth Development Office (FCDO) has issued warnings about extreme heat in four countries, including in Greece, where nighttime temperatures are sticking stubbornly above 30C in large parts of the country.

The FCDO has also issued heat-related warnings for Turkey, Cyprus and Spain:

Greece: "Greece can experience extreme natural phenomena such as earthquakes, wildfires, extreme heat and flash floods.

"Take extra care when planning a hike or walk, especially during higher temperatures than you are used to. Trails often lack shade and the quality of route markings can vary.

"Do not light fires as it is both dangerous and illegal due to the high risk of wildfires."

Turkey: "Extreme temperatures can affect many areas of Turkey over the summer months. Wildfires happen frequently in Turkey during summer."

Cyprus: "The Department of Meteorology of Cyprus issues warnings for severe weather, especially during summer. Weather can sometimes cause travel disruption."

Spain: "Temperatures in some parts of Spain can change very quickly. Take extra care when planning a hike or walk. Check local weather reports for warnings of extreme heat or cold temperatures."

Bas Amelung, Wageningen University environmental systems analysis professor, forecasts that popular holiday destinations like Spain, France, Italy, Greece, and Turkey could become unbearably hot in summers to come.

"Countries such as Spain, France, Italy, Greece and Turkey that currently attract the traditional 'sun and sand' summer tourists are likely to become too hot for comfort in the summer," he cautions.

"People take decisions based on their perceptions," Amelung further explains. "So if a large majority of holidaymakers thinks some European destinations will soon be 'too hot', they may well start adapting, either by going somewhere else in summer or by going to the same place in another season."

In Chios, the government declared a state of emergency following the outbreak of the fires on Sunday, leading to several villages being evacuated. As of Tuesday, the wildfires are still raging, with hundreds of firefighters, aided by aircraft, tackling multiple blazes.

The fires have causedsignificant disruption, including power cuts, water shortages, and property damage. Indeed, as of 24 June 2025, wildfires continue to blaze on the Greek island of Chios. Hundreds of firefighters, backed by aircraft, have been battling numerous wildfires in various parts of the island for the third day running.
