low tide

Today’s photo shows the beach at low tide. Lots and lots of sand. We enjoy long strolls, holding hands, enjoying the sounds of the water. However, the tides have caused us some difficulties. There have been times when we missed our walk because of high tides. And it was news to me that high and low tides are not consistently at the same time each day.

Following is a link to a Wikipedia article about tides which includes explanations such as

{\displaystyle {\text{tidal force}}\propto {\frac {M}{d^{3}}}\propto \rho \left({\frac {r}{d}}\right)^{3}}

Also, a link has been included for today’s photo saved on Flickr with the caption Low tide on Seabrook Island in South Carolina.
