Travelers visiting Greece in the summer should be prepared for extreme heat. As much as many wish to see the ancient sites, sit on the beach or go hiking, intense heatwaves with soaring temperatures can be dangerous. Some heatwave advice would therefore come in handy for visitors not used to the hot sun in the Mediterranean.

Just this week, BBC presenter Michael Mosley reportedly died from heat exhaustion while a 59-year-old American tourist on Amorgos is still missing after he went hiking and as is a 74-year-old Dutch tourist on Samos.

In the meantime, Greek authorities have closed schools, ancient sites including the Acropolis, and have stopped delivery services due to the extremely high temperatures expected to continue into Thursday.

That said, do not underestimate the heat and sun.
