I guess the moderator is tired of explaining the data. But, here is the dumb-downed version. The onshore prediction is based on off-shore data. The shoals on the East Coast (South of NJ) eat in to that energy. So, when you look at predictions for 4 and 5 days out, the data is accurate. But, as the swell approaches there are several factors that cause the predictions to drop in size. Therefore, instead of complaining about how Swell Info is wrong, just enjoy the fact that you can check the surf without actually going to the beach...like we had to back in the day when the line-up was a lot less crowded.
Keep up the good work Swell Info.
All this is true and I think everyone is very appreciative of all surf forecasting, maybe except magic seaweed which is constantlyway off on some areas northern south carolina and southern north carolina . Swell info is usually on, it is a difficult thing, you are providing a great service, but criticism will come with any forecasting, not just weather, ocean, or atmospheric conditions. Reason being is you can see patterns develop for some breaks off certain conditions and either leaves you with a bad taste in your mouth or stoked out the yin yang. Being that the east coast is very fickly, playing it down is a must in order to be rewarded.. Another point is traveling to breaks, sacraficing work time, spending gas money, etc. all to pull up to some weak surf that is blown out, which contradicts the forecast.. This is where it becomes knowlegde of the area and certainly studying the models to what you think is best for the given break. So, playing it down is actually very realistic and rewarding along this coast.
