When strong wind blows
across the ocean over a long distance, a series of long unbroken
waves form. This is known as a swell.
As the sign at Cable Beach Reads:
"When two large swells combine, the resulting
wave may double in height. If this wave bounces off a steep cliff
face or headland to combine with another large wave, it's size can
double yet again. Even during mild conditions, waves or swells may
combine to produce a churning wall of water that can sweep people
from headlands or beaches."
The 100 tonne boulder that lies in the middle of Cable
Beach was tossed to shore by a wave such as described above.
BE AWARE - BE CAREFUL - BE ALERT
Always watch children closely, especially in unpatrolled areas.
