Tide times
Tides and the dangers
A beach can seem like a vast playground but the tide can come in surprisingly quickly. As the tide moves up and down the beach, the depth of the water changes throughout the day, sometimes by as much as 10 metres.
Always keep a look out of the tide's direction while on the beach.
