Harmonic prediction from the Port Erin tide gauge (TICON-4); within about 2 min and 0.06 m of official times. Springs and neaps go by the day's largest tidal range at Liverpool as a percentage of mean springs: springs at 90% or more, neaps at 65% or less. The moon marks new, first quarter, full and last quarter.
Not for navigation. Heights are astronomical predictions only; weather and surge are not included. Check Admiralty tables and local harbour information before going afloat.
