Fires raged in the north, east and south of Greece, including on the island of Lesbos.
Officials ordered the evacuation of around 200 people on Sunday afternoon from Vryssa village on Lesbos as flames crept closer, some 500 metres (1,600 feet) from houses, the deputy mayor of western Lesbos told Skai radio.
Elderly women carried plastic bags with only a few personal belongings as they boarded the first buses to leave the village.
Thick clouds of smoke were already engulfing the first houses of Vryssa.
The blaze broke out a day earlier, causing the evacuation of hundreds of tourists and residents from the beachside village of Vatera.
At least four houses were destroyed in Vatera, as per reports, and fires damaged an unknown number of shops, hotels and beach bars in the village.
Dozens of firefighters early on Sunday clamoured to control the blaze, with four water-dropping planes and two helicopters in operation.
In the northeastern region of Evros, a wildfire was ablaze for a fourth day in Dadia National Park, known for its black vulture colony.
The fire has already destroyed nearly 500 hectares (1,220 acres) of woodland.
More than 300 firefighters battled to control the fire in Evros and by late Saturday the thick smoke forced the evacuation of the village of Dadias.
It was unclear how many people were evacuated.
"The most important thing for us is the safety of the villagers and all forces (which) will be deployed there," Evros governor Dimitris Petrovits told media.
The fire had already passed the raptor bird observatory and was closing in on the buildings of the protected area management unit.
Petrovits said collecting and treating injured animals was a high priority for the authorities.
In the Peloponnese, a southern peninsula, a fire that broke out early Saturday forced the evacuation of Chrysokelaria village.
By midday on Sunday, firefighters had managed to contain the fire.
A wildfire in mountains near Athens on Wednesday also damaged homes and forced hundreds of people to evacuate after gale-force winds earlier in the week.
Greece's worst wildfire disaster killed 102 people in 2018 in the coastal suburb of Mati, east of Athens.
The latest fires come after a heatwave and wildfires last year destroyed 103,000 hectares and claimed three lives in Greece.
Fires in parts of France, Spain and Portugal have already burned more land so far this year than was destroyed by flames in all of 2021.
The area, some 517,881 hectares, is equivalent to the size of Trinidad and Tobago.
