Foam returns to Alexandra Headland after ex-cyclone Marcia
The wild weather on the Sunshine Coast is creating sea foam at Alexandra Headland.
Dozens of locals are stopping to take photos of the rare lather brought about by high seas and strong winds.
Sea foam at Alexandra Headland created international attention in 2013 after Alexandra Parade became submerged.
A video of a car emerging from the foam and nearing hitting a police officer went viral.
Scientists believe sea foam happens because of natural detergent-like chemicals that sit in the microlayer of the ocean surface.
These chemicals typically come from phytoplankton blooms, seaweed or even terrestrial plants.
The waves, especially in big seas, can whisk these chemicals into a foamy mass.
