This service provides the predicted height and time of the tides at over 380 locations around Australia, Antarctica and the South Pacific. These are labeled as "Tide locations" in the legend.

The predictions are based on the effects of the gravitational forces exerted by the Moon, Sun and the rotation of the Earth and average seasonal changes. The actual tide height will be a combination of these effects and the weather conditions at the time. The effects of the weather are not included in these predictions.

The predictions are for seven days. You can select the start of the seven days up to 2 years ahead.

Important to note that the predictions are in daylight saving time when it is observed.
