It’s set to be another scorching summer, with extreme and prolonged heat waves forecast across many parts of the United States and Europe.The stifling conditions could impact millions of travelers and wreak havoc on vacations at some of the world’s most popular tourist destinations. Multiple heat-related deaths among tourists have been reported in Greece and Saudi Arabia in June following extreme temperatures in the Middle East and Aegean regions. Even those who have booked trips in traditionally cooler places may not be spared from the summer heat because of the growing unpredictability of weather patterns.Here are some tips on how to manage high temperatures when traveling in a heat zone.Check government guidanceIf a heat wave has been forecast at your destination, check government websites before embarking on your trip to give yourself plenty of time to plan and adapt. In extreme temperatures, governments often issue heat advisories warning people to stay indoors during peak heat hours and provide resources to help residents and visitors stay cool. In the United States, the National Integrated Heat Health Information System has a website with information and tools to help prevent illness and death during excessive heat.Tourist attractions also provide important updates about the conditions at the sights, including any scheduled closures, as a precaution against high temperatures. Some cities grappling with intensive heat, like Los Angeles, Miami, Athens and Melbourne, have assigned chief heat officers to prepare for the heat waves and lead emergency responses.Avoid peak sun hoursIt may seem obvious, but staying outdoors for prolonged periods of time when the sun is at its peak can put many at risk of heat exhaustion. Even if the temperature does not read exceptionally high, excessive dry heat or humidity can make an environment feel hotter than it is.Travel advisers are adapting itineraries, putting sightseeing in the cooler early morning and evening hours and prebooking tickets for their clients so they do not have to wait in long lines.“We tend to do activities and tours in the morning, then stop for lunch, and in the mid- to late afternoon you either go back to the hotel to sit by the pool or go to the beach,” said Gary Portuesi, a co-managing partner at Authentic Explorations, a New York-based travel company that specializes in Europe.Hiking in the middle of the day is also not advised. On June 5, Dr. Michael Mosley, a British medical journalist, died during an afternoon hike in a 104-degree heat wave on the Greek Island of Symi. Four more tourists, including an American man, have recently died in Greece as temperatures have continued to soar.“I would always recommend going hiking with a certified local guide and under no circumstances alone,” said Franziska Basso, a Milan-based travel adviser for Dreamsteam Exclusive Travel. “Of course, avoid the hottest hours of the day. Go hiking very early in the morning. And always stick to official hiking trails.”In some European cities, including Paris and London, air conditioning is not a given, so check if it is available before booking a hotel, restaurant or transportation to ensure you have a cool place to find respite from the scorching heat. Visiting a museum or other indoor sightseeing is another good option, but expect crowds at peak hours.Stay hydrated and take a siestaDehydration and heatstroke are among the most common causes of hospitalization during heat waves and can be prevented by staying hydrated and limiting alcohol consumption. During meals, consider eating foods like melons, cucumbers and celery as it can help to sustain hydration throughout the day. Always carry a water bottle with you and consider a parasol and portable fan to help keep you cool and shaded when outdoors.While your itinerary may be packed with activities and tours, the heat can take a toll on stamina, so consider following the European siesta ritual by breaking up your day with a short nap.“I’m telling my clients to adapt their itineraries and take advantage of the after-lunch siesta and then push their tours to later in the day when it’s cooler,” said Sarah Johnson, who owns Paper Ink & Passports Travel, a luxury travel company based in Pennsylvania. “There’s a reason they’ve been doing it in Spain and Italy for generations. Walking around in the midday heat and waiting in line could really hurt some people.”Wear cool clothingThe National Weather Service recommends lightweight, loosefitting, light-colored clothing for outdoor use as it reflects heat and sunlight. Hats and sunscreen are also recommended to protect the face and scalp from harmful UV rays.Just because it’s hot, doesn’t mean it will be dry. Heat waves can bring torrential rainfall, so be prepared.“My biggest advice to travelers is to be prepared — for hot or cold, dry or wet weather since one never knows,” said Laurel Brunvoll, the owner of Unforgettable Trips, a Maryland-based travel agency. “Pack layers.”Book a flexible tripEven after taking all the right precautions, traveling in a heat wave can be miserable, making it worthwhile to make flexible bookings and purchase “cancel for any reason” travel insurance to have the option to postpone your trip to a cooler time.Sensible Weather, a Los Angeles-based start-up that provides a weather guarantee for vacations and outdoor experiences, has recently added high heat protection to its coverage. Travelers booking through a Sensible partner in the United States will be able to add daily protection that will allow them to claim reimbursement for a booking if the temperature exceeds a threshold that is usually set between 90 and 100 degrees.“Our customers can still go on their vacations, but if it’s too hot for some hours of the day and unpleasant to go outside, you can hang out in the air-conditioning and we will reimburse you,” said Nick Cavanaugh, the company’s founder, who was developing the product while caught in a heat wave in Barcelona last year. Those on package tours are reimbursed for the average daily rate of their entire trip for each day that surpassed the heat threshold.For more travel advice, visit our collection of Travel 101 tips and hacks.
