As global temperatures break records and heatwaves intensify across popular tourism destinations, travelers face unique challenges and risks. From Europe to the United States, scorching heat is disrupting vacations and raising safety concerns. This guide provides practical advice for anyone planning to visit a heatwave zone, including how to cope with extreme temperatures, understand health risks, and navigate transportation and refund policies.
Which Regions Are Affected?
Destinations across the United States and Europe are experiencing dangerous heat. In the US, Grand Canyon National Park is forecast to reach 110°F (43°C) at low elevations, prompting officials to warn against midday hiking after several heat-related incidents, including two deaths on the North Kaibab Trail. In Europe, health warnings are active in France, Spain, the United Kingdom, and others. France recorded its hottest night since 1947, while Spain saw temperatures above 113°F (45°C) in Andújar. The UK issued a rare heat-health alert as schools closed and record highs were predicted.
Is It Safe to Travel to a Heatwave Zone?
Traveling to affected areas is possible with caution, but original itineraries may need adjustment. High-risk individuals—such as older people, young children, and those with chronic conditions—should reconsider. Visitors should monitor local government advice and be prepared for closures or evacuations due to wildfires, floods, or typhoons. In severe cases, canceling or rescheduling may be the best option.
Practical Tips to Cope with the Heat
- Plan outdoor activities for early morning, before 11 a.m., as temperatures rise throughout the afternoon.
- Frequently cool your wrists, face, and arms with cool water from public fountains.
- Take cool showers and air-dry when possible.
- Italian authorities recommend at least three hours daily in air-conditioned spaces—seek out museums, galleries, or restaurants.
- Wear loose, light clothing made from breathable fabrics and apply sunscreen regularly.
- Carry a handheld fan—it can make a significant difference.
- Drink more water than usual, even if not thirsty, and eat water-rich foods like fruits and salads.
- If you have asthma or other health conditions, consult a doctor before travel and ensure your accommodation has air conditioning.
- Purchase travel insurance that covers medical expenses and cancellation if a doctor advises against travel.
Health Risks to Be Aware Of
Extreme heat can cause heat stroke and heat exhaustion, which may be fatal. According to The Lancet, approximately 489,000 heat-related deaths occurred annually between 2000 and 2019. Heat stroke symptoms include body temperature over 103°F (39.4°C), hot red skin without sweating, headache, dizziness, and fainting. Heat exhaustion involves heavy sweating, muscle cramps, pale skin, and nausea. Seek immediate medical attention if symptoms appear. Humidity can worsen breathing conditions, even without wildfires.
How Heat Affects Transportation
Heatwaves disrupt all modes of travel. Flights may be delayed or passengers bumped if planes become too heavy to take off in high temperatures. Train tracks and roads can buckle; in 2022, London painted rails white and wrapped a bridge in foil. Highways may close due to flash flooding or wildfire risk. Public transport may lack air conditioning, making journeys uncomfortable. If driving, carry extra water and snacks and prepare for unexpected delays.
Can You Get a Refund If You Cancel?
Heatwaves are typically not covered by standard travel insurance unless an official travel advisory is issued—which is rare. However, if heat causes flight cancellations, airlines may offer refunds or rebooking. Some hotels may allow cancellations without fees; check your booking terms. Travelers with pre-existing conditions that worsen in heat may have limited recourse.
Do Europeans Have Air Conditioning?
Air conditioning is far less common in Europe than in the US. A 2018 IEA study found less than 10% of European households have AC, versus 90% in the US. Older buildings are designed to retain heat. Larger hotels in cities often have cooling, but smaller properties may not. Public transport varies—some subways have AC, but not all. Use apps like Citymapper to find air-conditioned routes. Cinemas are a reliable refuge; summer blockbusters like Toy Story 5 and Supergirl offer a cool escape.
How Long Will the Heatwave Last?
As of July 2026, there is no clear end in sight. Travelers should stay updated on weather forecasts and official warnings before and during their trip.
