Northwest Australia Tides

This part of Australia is known for large fluctuations between high and low tides.  While we've been here, the difference has been about 8 meters (25 feet).  That's measured vertically, so depending on the topography of the shore, the horizontal difference can be huge.  Farther north, the tidal difference can be as large as 11-12 meters.

Here are two pictures taken from the same spot with the same zoom settings at high tide and low tide.  Many of the mangroves are submerged when the tide is in.
