Karitane surfers have experienced foam surfing, as the New Zealand surf spot got infested by fluffy-covered waves.

A large amount of thick brown foam has invaded the line-up. New Zealand surfers have ridden unusual waves with a 330ft area covered up with a strange happening.

But these murky waves have an explanation. The region of Karitane has been suffering severe floodings and flood water has been coming out into the sea.
