Back to back weekends, early in the week, Friday and Saturday hold the promise of head high and overhead perfection. As the week progresses, the promising swell shrinks and dwindles to just a typical average waist high crappy wind swell. Mother Nature is a playful creature, she giveth and taketh away.
Wrong! If the forecast says, then it will come. You cannot dispute the stay power of a surf forecast, for it is set in stone. Idea: I need to take the forecast models, and the computers that run them, to AC. I'd be rich in days, and I would select 25 SI users for a month long surf trip to the Banzai Pipeline!
I used to check the stone forecast back before the newspaper and the telegraph became prominent. SI is pretty money in the short term 24-72 range, no one can predict a week out accurately all the time. Makes for good dinner party conversation though. "Say Winston, did you see that large north east swell forecast for a fortnight from heretofore? Pass the Grey Poupon."
The best is when you see the report look like doggie doo, and go check it due to boredom, and "just in case", and it is breaking nicely, maybe even firing on sets, and you score it before the whole crew has a clue.
I find that the model tends to start out "hot" with long range projections, then dwindles as the day gets closer, only to jump back up a few days in advance
