A week of king tides is just about to end.
Wikipedia tells me that king tide isn't a scientific term, but originated in Australia and New Zealand as a way to describe the highest tides. They're due to the Earth being closer to the Moon, and they're far more dramatic than you'd anticipate when told that high tide will be about 60cm higher than usual.
Incidentally, Wikipedia also has this to say about tides:
Tides are driven by the relative positions of the Earth, Moon, and Sun, the elliptical orbits of the celestial bodies, land formations, and relative location on Earth.
I've just finished reading The Luminaries, and it is potentially due to this that this sentence fills me with such wonder, awe, and that sudden jarring feeling that happens when you realise how truly insignificant you are.
I took these photos down at Cox's Bay just after high tide, when the water was on its slow way out. 60cm makes more of a difference than you'd think; the bay looked like a giant bowl about to overflow.
P.S. Don't read the comments under that link to The Luminaries. It's sad that 'don't read the comments' has to be applied to a discussion about the winner of the Man Booker prize, but…it does. I suppose there's a certain painful irony in some of them, but it's still not worth it. Just focus on how amazing this universe we live in is.
