Danger of sneaker waves that will suck you off the beach or rocks in an instant.

It seems a very placid, enjoyable, and secluded get-away from cities, noise, and urban pollution.

Yet this environment can be fatal to those who take risks or ignore warnings:

I did near hundreds of cases of people being sucked off the shore or rocks there, only to have a less than 10% of survival.
The seas can be lethal there, and those ignorant or that do not pay attention to warnings put themselves,
friends, family...and Yes, Responders at risk.

WOW... almost like a mini tsunami.

Learn something new every day.

A sneaker wave is created when the crests of two swells combine.

Example: There might be a West swell of 4 feet at 8 seconds between crests,
then also a SW swell of 3 feet at 12 seconds. When to two combine during those intervels
there could be a total swell of 7 feet.

They are pretty easy to predict if one was to examine the coastal ocean forecast for an area.

This forecast indicates there could be sneaker waves of up to 6 feet created:
