It is worth noting this is for the purpose of video games or visual effects not for scientific/operational simulations of the ocean.
Daily operational wave forecasts are available from NOAA's WaveWatch3 model here https://polar.ncep.noaa.gov/waves/wavewatch/ . These data products are wildly used by a variety of services including surf forecasts.
NOAA's Great Lakes Environmental Research Laboratory also publishes nice graphics of the WaveWatch3 forecast for the great lakes https://www.glerl.noaa.gov/emf/waves/WW3/
EDIT: So many interesting scales of wave research too!
Here is a very small scale study: https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/201...
