Annual tide tables are found in the Littlehampton Harbour Port Information Booklet, pick up a copy at the Harbour Office or various other locations across Littlehampton. The controlling depth for the harbour is the level of the Littlehampton entrance bar which extends 600 metres southwards from the end of the West Pier and is 0.9 metres above chart datum. The depth of water covering the bar can be calculated by subtracting 0.9 metres from the height of water indicated on the tide boards situated within the harbour. It also important to factor in real time swell conditions when deciding on an under keel clearance.
MHWS – 5.9m, MLWS – 0.4m, MHWN – 4.4m, MLWN – 1.7m, Spring range – 5.5m, Neap range – 2.7m
Rule of Thumb: Regardless of springs or neaps cycle 2½ hrs before HW until 3 hrs after HW there will be at least 3.4m on the tide gauge and so 2.5m over the bar.
