The boss of TUI has said heatwaves and climate change could prompt people to take their holidays in spring or autumn and choose cooler destinations.
Sebastian Ebel, chief executive of the tour firm, said holidaymakers might choose to travel to Greece in November, benefiting the travel industry.
Destinations such as the Belgian or Polish coast might become more popular, he added.
TUI said July’s wildfires in Rhodes had cost the firm €25m (£21.5m).
TUI said 8,000 of its customers had been evacuated from the Greek island. However, the German company said 80% of its guests on the island were unaffected.
