This is one of the most fascinating threads I've read in years. Never 'warm salt' fished in my life. A real learning curve here. Fished the 'salt' up in Puget Sound close to 30 years ago, but if water conditions were rough (waves over 2 foot) you didn't step in over your knees. Even that shallow the weight/force of the water was amazing!
Comment above about waves in sets of seven was even true in what would be considered to be 'sheltered water.'
