Where is the best free wedsite to get Current data on wave height, swell period and STP (steepness). I searched noaa and failed to find todays forcast for these things. Would someone clue me in on this subject ? A good iphone app would be good too, free or not. Thanks any help

If you are fishing near shore this is a good website

http://www.magicseaweed.com

You can then look up conditions along the Texas coast.

magic seaweed is honest, ive found some websites to sugar coat swells and i hate it....., magic seaweed has been honest every time ive used it( 4 trips now)

I use weather underground marine buoy which gives a pretty accurate measure and forecast.
