Interesting high/low tide pics

In the area I live high and low tides are not very impressive so these are amazing to me.
Just like people come to see Mangrove swamps here.

Pretty pics of high/low tide.

Re: Interesting high/low tide pics

Been in some places like that over the years... sure makes dinghy management interesting when going ashore! To say nothing of being very careful when anchoring.

Folks who deal with tidal ranges like that regularly must get a heightened ability to judge things by looking at sun and moon, as well as reading tide tables very carefully.

Cheers,

Jim

Great pics. It's not as much as some places, but we have a 10'-13' tide swing here. Those pics make me want to go do a time-laps video.....

Re: Interesting high/low tide pics

British Columbia, Canada has tides exceeding 20 feet among islands and fjords that produce currents that can exceed 15 knots that makes for memorable cruising..

Here are , and . Most people pass through these areas at slack tide. If you are not at slack even moderate currents are unsettling when a large swirler suddenly moves your boat sideways towards a rocky shore. Such areas are on the charts, and predicted currents are available.

Third picture down is the village of Staithes in Yorkshire where James Cook once lived. Place used to be one of the biggest fishing ports on the NE coast of England.

Fourth Picture is the St. Mary's Lighthouse at Whitley Bay, Northumberland

Sixth Picture is Blackpool, for some reason, very popular with the Scots during the summer.

That looks like Bedruthan Steps in Cornwall.

I learned to sail on an tidal river estuary that was a mile across at high tide, but the channel was 15 feet wide at low tide. You timed everything around the tide.

Re: Interesting high/low tide pics

Cool pictures. But I have a dumb question. The web site says the photos are taken 8 or 16 hours apart.

Why not 6 or 12? I've heard of diurnal, semi-diurnal and mixed tides, but never anything 8 or 16 hours apart. Is this something unique to the UK? Or is the web site just wrong?

Actually not dumb at all. Since the lunar day is 24 hours and 50 minutes long and the earth rotates through two tidal bulges in that time, high tides will be spaced 12 hours and 25 minutes apart. Tide prediction is rather complicated and depends on the influence of the moon, the sun, and the shape of the shorelines. NOAA has more information here.

Right. Which is why I asked. I know some isolated locations around the world have oddball tides due to geography and bathymetry. But 8 hours is closer to 1/3 of a lunar day, so I fail to grasp how you'd get consistently high and low water 8 hours apart. I assume it's a mistake, but I stand ready to be educated.
