In case you didn't read this on home page news section:
As of 6/23 8am:
The current swellinfo time plots are a bit funky right now, as we had to perform some maintenance on our wave models. You'll have to ignore the 0 to 48 hour timeplots, and then past 48 hours it should be good. The time plots and all forecast data should be back to normal on Saturday.
Just to give you a heads up, we are working on some other cool forecasting features that will be implemented in the near future : )
