Not just you, stuck on Wed as well. Not that it matters much for me sitting on this part of the "Lake of Mexico".
Your right... Everything on the site is up to date, but the "swell table" (exception: Socal). This will be fixed shortly.
The forecast hasn't updated for me since yesterday and is still showing yesterday's forecast but grayed out. It's doing that for the swell table, text forecast, and wave maps. Same with the mobile app.
