Example of a north Pacific animated surf forecast available from stormsurf.com. The animation shows a storm generating 14 to 16 foot surf for Hawaii's northern shores, arriving on Sept 27th, 2012. This video is a bit fuzzy, and the animations on stormsurf.com are better quality.
This is Keiki Beach where you can bring your children to swim or just be on the beach. It is very safe for children as there are four life guards looking out for children. Also, the water is not that deep for children but it goes deeper as you go out further.
