This is a split screen video that compresses over an hour of surfing into just over 5 minutes. It's a great way to see how much this surf spot changes as the tide drops.
notice how there are two main waves on river left, with a short time when people can catch the stuff in the midde. Towards the end of the good surf period, boaters will often head way over to river right where a wave/hole forms at lower levels.
Watch towards the end of the video how the wave on the left side of the top screen suddenly turns into a hole. It's a good blasting spot that washed towards the middle.
