Veranda Time & Tide clock by Weems & Plath

For over three months i've been living near the seaside, and still i have no idea about the tides.

i've come to the point where i recognize high tide, which means that whenever i'm walking towards the sea with someone who's not from around here, i can say in a proud 'don't-you-know'-kind of way: "It's high tide."
(recognizable by the teeny tiny strip of sand left in front of the beach bars, it's kind of obvious, actually)

Sadly that's still as far as my knowledge stretches. Maybe if i had a proper clock like this one, the whole tidal-thing would slowly start making sense.
