Late high tide this morning

The tide seemed to be extremely high in my little part of Sydney Harbour while I was out jogging this morning, so much so that I had to hang off a wall and inch my way along the edge of a cement culvert thing to stay out of the water (I didn't want my shoes all soaking and squelching for the rest of it!) where normally there is no water - or very occasionally there is only a little water. So I googled to see if there was any particular reason, out of curiousity, and according to this table, a late high tide was predicted for today months and months ago - all to do with the usual moon phases - and tomorrow is set to be even higher! For some reason I find that sort of thing interesting (and tomorrow might need a re-route). I rather like it that the ocean tide interrupts my life.
