If you are wondering why I am posting images from winter, the reason is that the weather here lately has been perfect, max 28, min 18, blue skies, and no clouds. Terrible for photography – not a decent sunrise or sunset anywhere!
This image is of the beach at Cosy Corner (down towards Cape Leeuwin). The green is a weed that grows on the reef over winter, and it can be a real lime green colour. As summer approaches the sun bleaches the weed, and it turns white. Later in the summer this gets covered by sand. However when the weed is visible (green or white) it contrasts beautifully with the colours of the sand, and ocean.
