swell charts in retrospect
If you are familiar with the NETCDF4 format here is a 30 year (1979-2010) wave hindcast in retrospect which was published I think in the last year or so (Bureau of Meteorology Australia, CSIRO Australia 2013.).

For someone who is not familiar with matlab/c/fortran/python/etc.. it is probably not an option to extract this data. I am sadly a bit limited with time but if you need something specific I can code up a small proggy and show you the results. Keep in mind that this data is gridded and interpolated in between grid points, so the resolution is limited! For the Australian coast the resolution is increased however.
I dont see an option on this site to post pictures so I cant post an example.
Cheers
Edit:
I found this figure that shows the resolution for the different regions on the world map:
https://data.csiro.au/dap/SupportingAttachment?collectionId=7847&fileId=77
So if you are lucky the region of interest has a grid point spacing of 7 or 18km :)
If you are in NSW you can request wave data from the MHL network of buoys - 7 locations across the state, spanning up to 30years. This includes height, period, direction and others (100's of parameters) that are measured data rather than modeled. See this for more information: http://new.mhl.nsw.gov.au/data/realtime/wave/
There is data online for the last few days if you are looking at recent events, but if you want older records then you need to make a data request. Or you can contact me directly: ben.modra at mhl.nsw.gov.au
There's similar operations in other states if you live elsewhere.
You have to wait for delta/quadrant star Y20 too line up with BOM first....
Then MHL network will fire up.
Thats what I have found..
Serious.
Hey bmod do you know how to find info for the realtime swell bouys of southern & western australian coasts ? historic data ?
Some weather nerds may find this interesting..... http://nomad3.ncep.noaa.gov/cgi-bin/pdisp_6p_r1.sh?ctlfile=pgb.ctl&varli...
That was my primary source of weather data for about 5 years SD! Used to plot thousands of charts every day via the Nomad servers. Still do occasionally if I need to retrace my steps.
Cheers, Ben.... here's another one I use at times...... Takes a bit of getting used to, but not too bad

Sheepio I need a pilots license to drive that thing:)
Give me some directions please, would not have a clue, its not lining up with quadrant/ delta Stephen Hawkins y20189999 star system at all.....?
Yeah SD, Wunderground have a great range of weather data, we use that as a backup sometimes.
Welly , Get captain cut and paste to help ya'........... ;)
Just for basics, scroll down to the bottom of "field", click "msl & thick mean sea level pressure"......... In "map projection", click "Aust".... Then click "plot".
Just play around with it from there , welly......
@welly just stick to driving your Kodak and get the yowie pic
Cheers Sheepio, will have a go thanx champ.
Udo, your right I'm forever trying, but not with that kodak as wifey won't let me touch it (the Kodak of course).
Putting some of my own 2 cents of research up on Yowie Hunters as we speak.
Gonna wait for the latest non infrared camera, thats coming out soon and use rope access to get up real high in the gummies to set it up :)
Anyone know of any good sites to look back at charts on specific dates in the past? Also is there anyway on this site or others to get other specifics such as swell period, size, direction on any given date in the past?
