Massive waves of up to 13 feet (four metres) are pummeling the coasts of Peru, leaving scores of ports closed on Saturday, authorities said. Peru closed 91 of its 121 ports until January 1, the National Emergency Operations Centre said on its X social media account.

Callao, which sits adjacent to the capital Lima and is home to Peru’s largest port, has closed several beaches and barred tourist and fishing boats from venturing out. Many beaches along the central and northern stretches of the country were closed to prevent risk to human life, authorities said.
