The appearance of larger than average waves is a known statistical phenomena to sailors---or should be. Looks like these guys might want to learn about the same rules (especially the two guys that reappears in the channel at 47 seconds)

So, if there are regular 10 foot waves, you should plan with startling regularity, on running into 20-25 foot high waves that will appear to come "out of nowhere"

This translates, BTW, into prudent navigation; since you know that waves start to "break" when the bottom is half the depth of the wave height, in a 10 foot swell, you should stay in water 25 feet deep with your boat unless you want the way-to-frequent for comfort big wave to come crashing down on top you as it "breaks" rather than sliding underneath your boat.

The most recent sailing accident attributable not following this rule was the sinking of the sailboat "Low Speed Chase" off the coast of the Farallon Islands (San Francisco Bay)---when she shaved a corner and ventured into the shallows and was crushed and sank by a breaking wave---(drowning some of her crew and the captain).
