Not in and out, but up (or down) the coastline? There are various times given for high and low tides all along Long Island, and I presume there’s some rhyme or reason to it, though this tides chart doesn’t seem to suggest any real pattern offhand. Is there some pattern I’m not seeing based on geography generally, or is it all a matter of factors others than geography (depth of bay, the mood that Poseidon is in that morning, stuff like that).
If you want a specific inquiry, when I go running on the beach I often choose the direction I run in so I won’t be staring straight into the sun as I run, but I’ve been wondering if the low tide could be moving along the shoreline with me, or against me, and if so, how quickly–much faster than I run, much slower, etc. or whether this is impossible to predict on a regular basis.
