Spanish Prime Minister Pedro Sánchez spoke of a "dramatic situation" and urged people to take great care. Three fires were burning west of Madrid, at Villa del Prado and San Martín de Valdeiglesias.
French Interior Minister Laurent Nuñez said 40,000 people had either been or were in the process of being evacuated from the Cap Ferret peninsula, which has the Atlantic on one side and the Bay of Arcachon on the other.
Local prefect Sophie Brocas said 53 homes had been lost as well as a campsite, but that 2,000 houses had been saved
A local councillor said 2,000 evacuees from the peninsula had already arrived by boat in the port of Arcachon on the south side of the bay.
Fire and rescue chief Marc Vermeulen said the wildfire had spread rapidly at the end of Thursday and into the early hours of Friday. Authorities then took the decision on Friday morning to begin the evacuation of the town of Arès, which lies south-east of Lège-Cap Ferret on the Bay of Arcachon.

Further down the Atlantic coast, around the town of Biscarrosse in France's Landes region, another major fire that began on Thursday afternoon has prompted the evacuations of more than 23,000 people.
About 18,000 people in Biscarrosse and 5,000 in Parentis-en-Born had to leave their homes, campsites, a nursing home and a summer camp.
Landes prefect Gilles Clavreul said the fire around Biscarrosse was not going to be out by the end of Friday, with winds of up to 50km/h (31mph) and temperatures of 36-37C.
No further casualties have been reported overnight in south-west France, although two firefighters died on Tuesday while tackling a blaze near Bordeaux airport.
French President Emmanuel Macron said on Thursday night the wildfire situation in the country was "very tense" - especially in the Gironde region.
Macron said he had asked for help from the European Union, and that support would soon come in the form of aircraft from Croatia, Portugal, the Czech Republic and Slovakia.
Headmaster David Morton, 53, from Gloucester had been on holiday with his wife and sons when they received an emergency alert via text overnight on Thursday instructing them to evacuate.The family were staying in a house in Petit Piquey, along the peninsula, and were woken up at 03:00 local time (01:00 GMT) by emergency texts and an alert on the property's landline.
"We got in our car, packed everything up as quickly as we could... and then set off and joined a very long, slow-moving queue of traffic," he told the BBC.
"Everyone was driving with their lights on, driving very slowly – there was lots of fire service people, ambulances, police on the other side of the road controlling things and we could see several fires in the distance as we drove."
As they drove past the fire near Lège, Mr Morton described the flames as "enormous".
"You could see the whole forest was on fire and that really brought it home what a major fire it was.".He described the evacuation as "well-controlled" with people being "very respectful and sensible".
"It's different from seeing it on the television… seeing it blazing out of control despite hundreds and hundreds of firemen and women helping."
The Cap Ferret peninsula has a year-round population of just under 8,000 but that can swell by 10 times that number in peak season.
Around 20,000 people within the Gironde region had been evacuated on Thursday many of whom were visitors to campsites on the peninsula.
Further evacuations also took place from La Porge on Thursday night which Ms Brocas said had taken place "calmly".She added that homes in evacuated areas would be monitored to prevent any vandalism.
"Significant resources" remain on the ground tackling the blaze while additional ground and air reinforcements are due in the coming hours.The public has been told not to go to the affected areas.
