Sea level and climate variability at Zanzibar

This study focuses on general features and variations of sea level at Zanzibar, and the relation of these to climate variability over the tropical western Indian Ocean during the 1997-1998 EI Niño and the 2000-2001 la Niña periods. The sea level data used in this study has been collected over a period of nine years from 1996 to 2004. Analyses have shown that the predominant type of tides at Zanzibar are semidiurnal with two high and two low water levels in each tidal day. Over the monthly cycle, two spring and two neap tides with different tidal ranges are observed. The tidal range may vary depending on the season of the year.
