Important Sea Level Information

From past observations, spring tides with heights of 2.80 meters or more (obtained through the BoM tide calendar), overtopping and inundation of sea water can be observed in low lying coastal sites along Tarawa. They worsen when associated with windy or gusty conditions. The causes of spring tides are different from those of storm surges. Storm surges are more related to storm events. Impacts from sea during storm surges can be observed although tide level is less than 2.80 meters.
