The long period swell was showing on the masonboro buoy, but I guess not making into the beaches there. Those long period swells that are generated in the middle of the North Atlantic are always really fickle.
SwellInfo is right on about 85 to 90% of the time. Just take a look at the crowd when it says it will be good. So what if they missed it this time. Remember back before Al Gore invented the internet and you actually had to go to the beach and check the surf for yourself? Probably not... I wish it said it sucked all the time and all the weiners would stop jumping in the line-up, but that is not going to happen.
