TEXT

Tides and tidal streams

  1. It is high water, full and change, at Port Pasajes at 3 h. 20 m.; springs rise 11 feet, and neaps 9 feet. The ebb stream has a rate of 2 knots an hour.

  2. It is high water, full and change, at Mundaca Bar, at 3 h. 0 m. and the rise is about 11 feet. The ebb stream has a rate of not less than 3 knots an hour at springs. The sea at times breaks a great distance from the bar.

  3. It is high water, full and change, in Portsmouth Harbour, at 11 h. 30 m. mean springs rise 13 feet, neaps 10V2 feet above the datum, which is a quarter foot above the level of mean low water springs.

  4. It is high water, full and change, at Chichester Harbour at 11 h. 30 m.; within the entrance springs rise 14 feet, neaps 11 feet. About 1 mile outside the bar the stream is rotary and of little strength turning to the. eastward an hour before low water and to the southward IV4 hours after high water; between the entrance points and over the bar it runs with considerable strength.

  5. It is high water, full and change, in Santona Inlet at 3 h. 0 m.; springs rise 121/2 feet, neaps 10V2 feet. The ebb stream is always much stronger than the flood and runs about 3 knots an hour at springs.

  6. It is high water, full and change, at San Sebastian Bay, at 3 h. 20 m.; but the tide is accelerated or retarded according to the wind; ordinary springs rise 12 feet, and neaps 9 feet. With strong winds from SW to NW the tide rises 1 to 1V2 feet above the usual level. The tidal streams are felt in the bay. On the coast in fine weather, the flood stream sets east­ward and the ebb westward. During thick weather the current runs strong to the eastward.

  7. The stream in the offing off Beachy Head begins to run east­ward at the time of low water at Beachy Head, and westward at high water. Close inshore between Selsea and Beachy Head the streams turn earlier than in the offing, the west-going stream commencing about 1V2 hours before it is high water at Dover and the east-going stream 5 hours after high water there. Southward of the Royal Light-vessel (Lat. 60°43' N, Long. 0°27'E), the two streams meet at 5 hours before high water at Dover, and separate one hour after high water at Dover. The east-going stream has a maximum rate varying from 3 knots at springs to 2 knots at neaps; the west-going stream 2 knots. Strong winds accelerate or retard both time and rate of the streams according to their direction.

  1. In the Park the eastern stream begins about 4V2 hours after high water at Portsmouth, and sets eastward, the western stream about l3/4 hours before high water there, and sets for the first 3 hours south-westward; at 3 hours after high water it slackens, and runs 216° true, gradually turning more southerly; the velocity never exceeds 1V2 knots but the nearer the Mixon is approached the stronger the tide runs.

  2. On the inner bar the flood stream at first sets weakly towards Southsea Castle, but at 3V2 hours before high water it sets towards the harbour with a velocity of lx/2 knots, which increases to 41/* knots in the entrance, gradually decreasing to 3 knots off the Dockyard. The flood stream off the Dockyard runs for 7 h. 12 m., continuing as a narrow stream for about 15 or 20 minutes after high water. The ebb stream runs for 5 h. 13 m., attaining a greatest velocity of about 2 knots at the entrance to Porchester Lake, which increases to 5V2 knots in the narrows at the harbour entrance.

  1. In Brownsea Road (Lat. 50°41' N, Long. 1°57'W) the flood stream commences 4V2 hours before the first high water, and the ebb stream three-quarters of an hour after the first high water. The flood stream at springs attains a maximum velocity of 3V2 knots, and the ebb of from 2 to 3 knots for about 3 hours, when it slackens or is sometimes reversed in direction until the second high water, then it again runs with a velocity of 3 knots.

  2. The tidal stream in St. Mary's Sound flows north-eastward on an average for 6 hours and ebb for 6 hours 25 m. in the opposite direction. The flood from the south-west divides and sets round the islands on both sides, the two streams meeting again in the north-east. The stream begins to set to the south­eastward about 4 hours before high water at Devonport and runs for 6V4 hours nearly in the direction of the channel. The stream passing south of the shoals off Samson Island is deflected northward and joins the other streams from Smith Sound, all these being deflected to the north-westward of Steeple Rock, where there is a strong tide ripple at springs. The rate of both streams is about 2 knots at springs.

  3. In Smith Sound the streams run in the direction of the channel and attain a velocity of 2V4 knots. The northerly stream commences at 3V2 hours after high water at Devonport, and runs for 7 hours, the southerly stream begins at about 3 hours before high water at Devonport, and runs for about 6 hours. In Gorregan Neck the northerly stream commences about 83/4 hours after high water at Devonport in a 276° true direction, but after the first hour it runs in the direction of the channel until it meets with the stream from the Bishop Rock.

13. About 2 miles off the entrance to the inlet, the stream sets east-south-eastward from the time of the moon's meridian passage until 6. hours after, and attains a rate of 2V2 knots; this stream sets south-south-westward into the inlet from the time of the moon's meridian passage until 5 hours after, and attains a rate of 2 knots for the first 2V2 hours, after which it gradually decreases. Then the stream sets towards Krasno-gorsk point, where it turns northward and sets over Jarengski spit and the bar north-eastward.
