The times given in the data in relation to Dover refer to the higher rise.
Rain and river water have an effect on the depths within the harbour, and the speed of the outgoing flow through The Run.
The Run is unstable and can often change in depth and in course, especially during the winter. During periods of high pressure the depths of water within the harbour and the run in could be reduced by 0.3 m which is of great significance with so little depth to spare.
With strong or prolonged winds from the South to the south-east a dangerous swell with a breaking sea on the bar can develop.
Make the approach from well out and well offshore on a bearing of about 290°.
As the water gradually shoals to around 2.5 m (at CD), you should be able to pick up the buoyage, lying to the north-east of the harbour entrance.
The town itself is very beautiful, and the harbour is unspoilt and an important nature reserve with salt marshes, reefs and sand dunes.Residents of the city reported feeling tremors in Linwood, Hornby, Port Hills and at Burwood Hospital.'Massive here in North beach.
