Sea Level Rise Mapping

A set of maps were produced to provide an initial indication of the areas that may be potentially impacted by increases in sea levels of up to 90cm by the year 2100.

These maps were based on static calm water conditions using topographical information currently held by Gosford City Council.

The actual extent of impacts may be greater or lesser than that shown, but the maps represent the best information that council holds at this time.

If you require further information on sea level rise, please refer to the Sea Level Rise Planning page.

King tide inundation map

King tides are especially high tides which occur at the time of the new moon or full moon during the summer and winter months.

At these times, the moon and the sun are in line and the gravitational pull is at its strongest.

On the Central Coast the highest tides occur during the winter months of June, July and August, and the summer months of December, January and February.

The highest tide of each of these periods is known as the king tide. The winter king tide usually occurs at night and therefore goes unnoticed.

Consequently, the summer king tide usually catches the most attention. King tides are particularly problematic for developed low-lying riverine and estuary lands throughout the Gosford local government area. 

Note: These maps are a communication tool only and are not suitable for decision-making.
