Nearshore Surf-Forecasting with SWAN from magicseaweed

Hi from France,

I read an article at Surfcore about your next wave forecast system using
WW3 spectra+SWAN:
http://surfcore.co.uk/node/1735

I try to do the same thing in France, only for a small area
around the Ile de Ré and the Ile d'Oléron (Les Alassins / Vert Bois).

I was wondering if it is a good idea to use the nww3 output (grib: hs,tp,
wave direction) close to my computational boundaries or use like you the spectral files?
Because with the spectral file I need a larger grid with SWAN and add a wind input
but maybe the results are more accurates (with a nested grid close to the coast).

My website with the nww3 grid output (like buoyweather), and the NDBC and French buoys

Thanks for your reply.

Thanks for your advices,

I think like you without the spectra you are missing something...
I think you can put more than 1 spectra for one boundary if you use
the spectral outputs of another wave model (not NOAA/WW3).
I have never used SWAN with the spectra files and my area is not very well closed :?
so to begin, I will try with boundary conditions forced with nww3
and test with the real world, if the waves want to come one day :-D
I will sent an email when it is done (maybe in 2 or 3 weeks).

Cheers
