About the tides at Koh Tao
The tide at Koh Tao is diurnal: mostly one high tide and one low tide a day. This month the tidal range (highest high to lowest low) is about 2.0 m. The biggest tides (spring tides) come a day or two after the new and full moon; the smallest (neap tides) after the quarter moons.
How this is made. These are computed predictions, not measurements or official tables. We fit tidal harmonics to a year of the Open-Meteo marine ocean model at the nearest ocean cell (5 km from the spot) and predict forward. On open coasts like this, our checks against official tide tables found high and low times usually within about 10 minutes and nine times in ten within 30 minutes, heights within about 10 cm. See the accuracy tests. Not for navigation: harbours, river mouths and lagoons nearby can differ.
