The Bangtao tidal prediction for Phuket is just that, a well educated guess based on years of observed data.
Many factors will affect the tide tables at Bang Tao including local winds and pressure systems. A margin of error of at least 10 minutes is to be expected with any forecast and its this level of accuracy we aim to achieve.
Data quality varies by port and country: large western commercial ports will be very accurate, small Asian fishing villages are probably going to be somewhat less accurate. If you think the tide tables at Bang Tao are wildly innacurate please let us know (please tell us what source you are comparing us with).
Bang Tao in Phuket is a quite exposed beach break that has fairly consistent surf. May-Oct (Dry Season) is the best time of year for waves. Offshore winds blow from the west southwest with some shelter here from south winds. Groundswells and windswells are equally likely and the ideal swell angle is from the west. Waves at the beach are both lefts and rights. Good surf at all stages of the tide. An uncrowded break, even when it is working. Watch out for dangerous rips.
