Traveling During a Heat Wave: Tips and Precautions

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.
