![]() The Severn Estuary has the second highest tides in the world – after the Bay of Fundy in Canada – and the highest in Europe. This is because the complex rhythm of the tides broadly follows the rhythm of the waxing and waning moon. The 8th Century British scholar and theologian, The Venerable Bede, wrote that the tides were somehow created by the breath of the moon. Sometimes the pull of moon and sun are in line (at new and full moon) and the highest, spring tides occur.īefore gravity was understood the tides were a great mystery to science and religion. Sometimes the gravitational pull of the sun (which is weaker on the earth as the sun is so far away) counteracts that of the moon and tides are lower. The gravity of the moon pulls at the earths surface, as water is “loose” it moves in response. Tides are caused by the combining gravitational pull of the sun and the moon in relation to forces created by the spin of the earth. Along parts of the Atlantic and Pacific coasts their rise and fall can be extreme. In the Mediterranean the tides are small. They vary from month to month, season to season and place to place. That’s the height of three double decker buses.Īll around the world the sea level rises and falls every day with the tides. ![]() On the Severn Estuary in Southwest England the all-important sea level can rise and fall as much as 14 metres in the space of 12 hours. They take place on the Amazon and the Qiantang River in Southeast China, where the event is held to be sacred and marked by temples and large crowds. Tidal bores are one of the most famous tidal effects where rising water from the ocean creates tidal waves which wash inland, up rivers. What’s known as a tidal bore – a wave of up to 2.8 metres – came in from the Atlantic on Sunday and a five-star bore (the largest waves that occur) coursed up the river on Monday morning. Gourmet meal (local producers), concert, entertainment for children, something to delight the whole family.Surfers and spectators gathered along the Severn Bore in Gloucestershire, England, in recent days to take advantage of the tidal wave that swept upstream. The village of Vayres, organizes as every year, the “festival of the river”. ![]() In addition, debris can be carried by the tide, be careful. Indeed, the rising waters may surprise you. A hell of a wave that you can surf for 10 minutes (for the most gifted of course)!įriends spectators, place yourself in height and not along the banks. The tidal bore moves at a speed of 15 to 30 km depending on the location. Surf, kayak, paddle, longboard, canoe and even jetski come to enjoy the show. Sure ! Like all waves, the Mascaret lends itself to sliding. What to check before leaving if the conditions are favorable. ![]() A tip? The town hall of Vayres provides a tide calendar on its website. There are two tidal bores a day, more than 730 a year, but only about fifty are truly remarkable. The wave is formed thanks to the large tidal coefficients: the higher it is, the more imposing the wave will be. And THE spot on the Dordogne side, at the foot of Castle of Vayres and the port of Saint-Pardon.Īccording to legend, the Mascaret comes from the name of a Girondin village, located at the point where the phenomenon occurs furthest upstream on the river: Saint Macaire, quite simply.īetween June and October is the good season to see the Tidal Bore in Gironde, on the Dordogne and the Garonne. ![]() On the Garonne side, head towards Langoiran or Podensac. Spots to enjoy the Tidal Bore in Gironde are a bit like mushroom spots, it's sacred and secret. When the tide goes up the course of a river, it collides with the descending waters, this creates waves, waves and presto, the tidal bore is formed. It is a natural phenomenon that occurs on certain estuaries. Here we reveal some of its secrets, because we are like that in Gironde, we share! This incredible natural phenomenon intrigues, questions and sometimes even fascinates. ![]()
