Tide & Tidal Range The Thames Estuary is macrotidal with a mean spring tide range of 5.2 m at Sheerness gradually increasing upstream to 5.9 m at Tilbury and 6.6 m at London Bridge (United Kingdom Hydrographic Office, 2003).
How big are tides on the Thames?
We can compare these levels with the maximum high tide recorded in the tide tables for Thames which is of 4.0 m and a minimum height of 0.0 m. The following graph shows the progression of the tidal coefficient in the month of November of 2022.
How far up the Thames do tides go?
Of the Thames’ 346km (215 mi) total length, 160km (99 mi) is in fact tidal, that’s close to half of the length. This section, which is known as the Tideway, stretches all the way from the sea until stopping at the first lock on the river in Teddington.
Is high tide the same everywhere in the UK?
The shape of the coastline and the bathymetry (water depth) result in different tide times around the coast of Britain.
How deep is the water under Tower Bridge?
The depth of the river changes drastically but it is 20 metres at its deepest.
Where is the biggest tide in the UK?
The Bristol Channel has the second highest tidal range in the world, only exceeded by the Bay of Fundy in Canada. This huge body of water is 45 km across in the west but narrows to less than 10 km by the time it reaches Clevedon.
What is the strongest tide in the world?
The highest tides in the world can be found in Canada at the Bay of Fundy, which separates New Brunswick from Nova Scotia. The highest tides in the United States can be found near Anchorage, Alaska, with tidal ranges up to 40 feet . Tidal highs and lows depend on a lot of different factors.
Why is the tide so big in the UK?
As the Earth rotates on its axis, the changing gravitational pull from the Moon powers two giant waves flowing around the coast of Britain.
How big are the tides in England?
Around the UK the tidal range varies between a minimum of 0.5 m and a maximum of 15 m in the Bristol Channel.
Can you swim in the Thames?
The PLA allows swimming to take place upriver of Putney Bridge through to Teddington. It is permitted in this area only but be reminded that it is still a busy section of the tidal Thames for leisure and recreational activities.
Where is the biggest tide in the world?
the Bay of Fundy
Located in Canada, between the provinces of Nova Scotia and Brunswick, sits the Bay of Fundy, home to the world largest tidal variations.
What countries have no tides?
Some bodies of water (the Mediterranean, Baltic, Black Sea, Caspian Sea, and Caribbean) don’t respond strongly to tidal forces. The reasons for this are a bit complex but basically it is due to their size and geographic nature. These areas are described as Non-Tidal.
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.
Are there sharks in the River Thames?
Spurdogs are also known as spiny dogfish, and they were almost overfished into extinction. These sharks have recently started showing up in the Thames due to warming and rising seawater and are not returning to an ancestral habitat.

Why is River Thames so brown?
The River Thames appears brown because there is silt on the riverbed. This silt is made up of fine particles which disperse in the water and make it look muddy.
Where is the highest tide in Europe?
Mont Saint-Michel
The highest tides in continental Europe are found at Mont Saint-Michel, reaching a difference of up to 15 metres between low and high tide. During high tides, the sea withdraws 15 kilometres from the coast and rises very quickly.
How long does high tide last UK?
12 hours and 25 minutes
There is a period of 6 hours and 12.5 minutes between a high tide and a low tide. Example: High tide is at 12pm – the next low tide will be at 6.12. 5pm (6 hours and 12.5 minutes) or there is a high tide every 12 hours and 25 minutes.
How long does the tide stay in UK?
There are two high and two low tides in each 24 hour period. It moves forward about half an hour with each tide, with one high/low tide every 12 hours and 25 minutes.
Where on Earth are tides the weakest?
It is weakest on the side of the Earth facing the opposite direction. These differences in gravitational force allow the ocean to bulge outward in two places at the same time. One bulge occurs on the side of the Earth facing the moon. This is the moon’s direct tidal force pulling the ocean toward it.
Why are tides smaller in Hawaii?
The Hawaiian islands lack a continental shelf, they lack sufficiently large bays, and they are out in the open ocean near an amphidromic point. On the other hand, places like Europe and north-western Australia have shallow continental shelves, large bays, and they are greater distances from amphidromic points.
