I chanced across this site while surfing the net. It's got a slick interface, with easy viewing of all the data garnered from the NOAA Wavewatch III model output.

surf forecast

...mega, pat reckons 30 minutes to look at the charts, 30 minutes chatting with the met. fella's and 30 minutes writeup for his forecast.
can someone please tell me why jerome aucan stopped filling in for pat when he was away?
Pat caldwell
I stopped doing it when Pat Caldwell's page moved from being a semi informal website on the university webserver to an official NWS webpage. I am just a graduate student (I m also finished), and the "caretaker" of the waimea and kailua buoy. Not good enough for NWS.
By the way, the buoy website (http://www.soest.hawaii.edu/~buoy) is constantly upgraded with new products, you just have to scroll down the frame on the left. I had local tide charts, and 7 days forecasts for specific Oahu locations

check out http://www.wavewatch.com
the wavewatch.com cams are nice, you can view kammies, monster mush, rp, ehukai, and otw, from new angles surfline doesn't have.
I guess one is from jamie o's house.

surf media war of the giants
On one side :
-AOL Time warner with Transworld surf, (+transworld skate, snowboard etc...) and surfline.com
On the other side :
-Primedia with Surfer, Surfing and Surfing Girl magasines, and wavewatch.com
No matter who wins,it shows you how much the surf industry is $$$

Here's a link you might like
real-time data from a platform i helped some of the Ocean eng. guys put out off Kewalo's
gives significant wave height, direction and a million other things.
updated every 20 minutes. sorry wave heights are in metres

oh yeah, good point
click on real-time data
that gives you a summary and some graphs if you scroll down.
H_sig is the significant wave height. this is just the average of the highest 1/3 waves. Zero crossing or spectoral is the method with which they calculate the wave height. The pressure sensor simply measures the weight of water above it. under a peak, there will be more water, under a trough, less. the zero crossing method takes the average of the two as the mean sea surface (zero height) and calculates wave height from every time this average is 'crossed'
however i was thinking about this yesterday. during south swells, the frequency (or period) is often very narrow, due to the distance the waves have travelled. This is why south shore swells seem more inconsistent than north. the more spread in the wave frequencies, the more consistent the surf.
however this inconsistancy might be screwing up the wave averaging.
If in 30 minutes there are only a few large sets (say 5'), and the rest small (say 2') then the average of even the top 1/3 waves is still going to be underestimating the wave that we (as surfers) are interested in.
Sorry about the babble. to actually answer your question H_sig (zero crossing) should give you wave height. although it looks too small to me, hence my rambling...

i've found http://www.magicseaweed.com to be a quite good resorce for us brits. they have started covering other countries as well now so might be worth a look.
