Super moon, super tide?

by Julie C.

During the summer months when we aren’t Field Trip Explaining; we’re exploring!

Last week, I headed over to the beach the morning after the supermoon or perigee-syzygy of the Earth-Moon-Sun system! Isn’t that a great term? Perigee means that the moon is closest to earth in its elliptical route. Syzygy of the Earth-Moon-Sun system means that those bodies are aligned, ie: a full or new moon.

My thought was that the tide would also be exaggerated. I headed over to Land’s End around 7am to check (here’s a tide chart for areas around San Francisco.) While the tide was very low, but it was only a little lower than last month’s low tide caused by the normal full moon…Which is good news because there were all sorts of amazing creatures to see exposed on the beach!
