The St. David’s pen...Trip Planning - Ramsey Island<br /><br />The St. David’s peninsula and the islands extend into the main tidal streams running along the E. coast of St George’s Channel. Consequently, large volumes of water are squeezed back and forth through Ramsey Sound and between the rocks and islets of the Bishops and clerks. Streams can run up to six knots, causing overfalls, strong eddies and confused seas. In addition to the main N/S streams, it is important to note that there are streams that do not conform to the general flow. <br /><br />The tidal streams begin at the following times:- <br /><br />2 ½ miles W. of The Bishops: <br />-02.25 H.W. Milford Haven N 2kn. <br />+04.00 H.W. Milford Haven S 2kn. <br /><br />Between Ramsey Island and The Bishops: <br />-02.55 H.W. Milford Haven N.E. 5kn. <br />+03.30 H.W Milford Haven S.W 5kn. <br /><br />In the narrowest part of Ramsey Sound: <br />-03.25 H.W Milford Haven N 6kn. <br />+03.00 H.W Milford Haven S 6kn. <br /><br />The North going, flood stream runs on either side of Ramsey Island, being at its strongest in the narrows between the Bitches and Pen Dal Aderyn. Where the stream flows through the Bitches, standing waves are formed and there is an extensive area of whitewater downstream, with an eddy stream returning S. along the east coast of Ramsey. South going eddies may also be encountered on the E. side of the sound from Point St. John to Penmaenmelyn. <br /><br />On the W. side of Ramsey, the North going stream runs strongly around Carreg Gwylan and Trwyn Bendro. Further offshore, at the Bishops and Clerks, the stream starts later than they do in Ramsey Sound, and run N.E. through the islets and rocks towards St. David’s Head. <br /><br />When streams are running strongly standing waves extend down the length of the sound and overfalls form around Horse Rock. <br /><br />The South going, ebb stream runs S.W. from St. Davids Head and between the islets of the Bishops and Clerks. The stream divides near Gwahan, one arm running through Ramsey Sound and another running W. of Ramsey Island. The stream strengthens where it flows around Trwyn Drain Du and Trwynllundain, and there are strong streams on both sides of Carreg Gwylan.<br /><br />A strong N.W. going stream is known to occur off Trwyn Sion Owen at the beginning of the South going stream. On the W. side of Ramsey Sound, north-going eddies run from Ynys Cantwr to the Bitches. North going eddies form along the coast of the mainland from Porthstinian to Point St. John and an eddy stream runs N.E. into Porthmawr between Carreg-gafeilog and the mainland.<br /><br />Important Note - At the south end of Ramsey, streams run strongly through TwII y Dillyn. According to local knowledge slack water here is 2hrs after local H.W. The E. going stream then runs for 3hrs. A short period of slack water is then followed by a W. going stream for 9hrs, which at its strongest can exceed 6kn. Streams also run strongly through Twll Y Gwyddel. <br /><br />Streams run along the S. shore of the St. Davids Peninsula, between Porthclais and Pen Dal Aderyn. They are generally weak, but may run quickly around Carreg Fran and between Pen Pedol and Pen Dal Aderyn, where the W. going stream joins the main stream in Ramsey Sound. <br /><br />Slack water in Ramsey Sound is, according to local knowledge 2 ½ hours after local H.W. and L.W. i.e. 3 hours after H.W. & L.W. Milford Haven. It may last about 15 minutes on neaps but is considerably shorter on springs and may sometimes appear to be non-existent. <br /><br />Tidal differences. <br /><br />H.W Traeth Mawr + 00.10 H.W Milford Haven. <br />H.W. Ramsey + 00.30 H.W. Milford Haven. <br /><br />Opinion vary as to the exact time of H.W. and slack water in the Sound. The times at which the streams begin may vary considerably from those given hereSea Kayak Markhttps://www.blogger.com/profile/12372699464975270081noreply@blogger.com
