Wildfires are frequent in Greece during its hot, dry summers. In 2018, a massive fire swept through the seaside town of Mati, east of Athens, trapping people in their homes and on roads as they tried to flee. More than 100 died, including some who drowned trying to swim away from the flames.

Extreme heat has gripped countries including France, Greece, Italy, Portugal and Spain, with record temperatures, health alerts and wildfires.
