The UK government has issued a new urgent travel alert for Greece, effective Saturday, July 5, 2025, due to a significant rise in wildfire threats, extreme summer heat, and increasing occurrences of natural disasters such as earthquakes and flash floods. With millions of British tourists expected to visit Greece during the peak holiday months, the Foreign, Commonwealth and Development Office (FCDO) is warning travelers to remain vigilant as the country faces a heightened risk of climate-driven emergencies. The advisory stresses the importance of preparing for rapidly changing conditions, staying informed through official Greek emergency channels, and taking preventive measures to avoid triggering fires, as even unintentional acts can lead to criminal charges under Greek law.

As Greece enters its peak summer season, the FCDO’s critical update, released on Friday, July 4, comes amid escalating temperatures across southern Europe and growing concern over public safety. Annually, over four million British travelers are drawn to Greece's islands, historic landmarks, and beaches. However, with the climate becoming increasingly volatile, UK officials urge vigilance, particularly during the fire-prone months between April and October.

The FCDO’s update specifically highlights the “high risk of wildfires during the summer season,” noting Greece's vulnerability to extreme heat and dry conditions. 2025 has already seen record-breaking temperatures and numerous wildfire outbreaks, prompting authorities to enhance public information and protection efforts. Greece has already contended with several blazes on its mainland and islands this year, fueled by strong winds and prolonged heatwaves, which have strained local firefighting resources and necessitated evacuations. British travelers are cautioned that wildfire situations can develop rapidly, often leaving minimal time for reaction.

Beyond wildfires, the FCDO also points out Greece's susceptibility to other natural hazards. These include earthquakes, as Greece lies in a seismically active zone, with tremors occasionally disrupting travel and infrastructure. Extreme heat, with temperatures often exceeding 40°C in July and August, poses risks of heat exhaustion or heatstroke. Furthermore, flash floods can occur from sudden, intense rainstorms, overwhelming drainage systems, particularly in urban or coastal areas. Travelers are advised to anticipate such possibilities, closely monitor local conditions, and adhere to guidance from Greek civil protection authorities.

A crucial piece of advice from the FCDO is for UK nationals to ensure their mobile devices are registered to receive emergency alerts in Greece. The country utilizes a system linked to the emergency number 112, which issues real-time warnings for fires, earthquakes, and evacuations. Visitors should check with their mobile provider or ensure roaming capabilities are enabled to receive these vital alerts, which can significantly aid in evacuation scenarios or emergency response coordination. The FCDO also recommends following @112Greece on social media platforms for the latest updates from Greek authorities.

While travelers prioritize avoiding danger, the FCDO also emphasizes the shared responsibility in preventing wildfires. Many fires originate from careless or accidental behavior, often due to unawareness of consequences. Travelers are strongly advised to dispose of rubbish responsibly, as glass, plastic, and other materials can spark fires in dry conditions. Properly extinguishing cigarettes is vital, as even a small ember can ignite dry grass or brush. Avoiding open flames and barbecues is prohibited in rural or forested areas, and is considered a serious offense. In Greece, causing a wildfire, whether intentionally or through negligence, is a criminal offense, with penalties including fines and imprisonment, especially if property damage or injury results.

If travelers find themselves near a wildfire or threatened by its spread, they are urged to call emergency services immediately by dialing 112. They must follow instructions from local authorities without delay, remain calm, and evacuate early if warned, avoiding congested roads or areas at risk of becoming blocked by fire or debris. Staying informed through reliable sources, such as official government websites, the local embassy, or tour operators, is also crucial. Airlines and travel providers are often notified during evacuations or emergencies and may assist with rescheduling flights or arranging return transport to the UK.

To mitigate risks while enjoying their holiday, UK travelers should check travel insurance coverage to ensure it includes natural disaster situations. Downloading the Civil Protection app is recommended for extended stays. It is also wise to keep important documents and medications accessible in case of rapid evacuation, stay hydrated, and avoid strenuous activity during the hottest parts of the day. Monitoring air quality in wildfire-prone regions is important, especially for those traveling with children, the elderly, or individuals with respiratory conditions. With the Mediterranean region experiencing more intense climate impacts annually, the UK government’s updated advisory for Greece serves as a timely reminder for tourists to prioritize safety alongside enjoyment. While Greece remains a stunning and popular destination, changing weather patterns necessitate more informed and cautious travel behavior. By staying alert, respecting local regulations, and planning ahead, travelers can ensure their summer getaway remains memorable for the right reasons, avoiding an avoidable crisis.
