The double high tide in the Solent is a geographical anomoly caused by the back pressure of water flowing South West out of the Solent holding the water in Poole Harbour, which faces East.
Why does Poole Harbour have 2 tides?
Poole Harbour’s Tidal Anomaly:
Poole Harbour is both close to a Nodal Point but also a standing wave located in the English Channel which causes this. It also means the tidal stream at Poole Harbour entrance ebbs and flows 8 x a day (rather than x 4 like most other areas).
Why are there 2 tides?
Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes.
Why does the Solent have two tides?
700 million cubic metres of water weighs 700 million tonnes and creates a “tidal stream” as it enters, and then again as it leaves the Solent. This creates two “high waters” (“HW”) and two “low waters” (“LW”) per day, alternating approximately every 6 hours or so.

Where is the fastest tide in the UK?
Pentland Firth, the passage that lies between the north coast of Scotland and the Orkney Islands, has tidal streams that are amongst the fastest in the world, running at up to 16 knots.
Why does Weymouth have 4 high tides a day?
Well, that is because that is how long a lunar day lasts. As the earth rotates on its axis, the moon travels around the globe in the same direction. That means as the earth returns to its original point (24 hours), the moon has moved further along its orbit. So the earth needs a little longer to catch up.
How does Southampton have 4 tides a day?
Why are tides formed 4 times a day in Southampton, the coast of England? Because of the presence of the Isle of Wight which divides the approach to Southampton Water into two, the Solent to the West & the Spithead to the East so the tide comes up one way and then up the other way as the first tide goes out.
Why are tides so different in UK?
Why are the tides not the same around the entire coast of Britain? The shape of the coastline and the bathymetry (water depth) result in different tide times around the coast of Britain. Tides travel as waves (moving at about 20 ms−1 in shallow seas and at hundreds of ms−1 in the deep ocean).
What is special about Poole Harbour?
Harbour Information

Why is there no tide in the Caribbean?
There are tides in the Caribbean, but because there is no bloody great continental coastline for the ocean to wash up against pulled by the Moon’s gravity, you don’t get the dramatic tides you see on continental coasts.

What is the strongest current in the UK?
Cap de la Hague
Due to the English Channel’s geography, it has extreme tidal currents, the strongest recorded at 13 knots.
What is second tide?
A second tidal bulge (the second high tide of the day) is created by the centrifugal force of the Earth and Moon orbiting a common centre of mass. This is the same force you experience when you feel like you are going to be thrown off as you spin around on a roundabout.
Is it better to fish tide in or out?
Tides and Rock Marks
Some rock marks offer better fishing over low water, while others such as rock ledges and cliffs may fish better at high tide as the water level rises and provides a greater depth of water to cast into.
