https://www.fnmoc.navy.mil/PUBLIC/ then go to the Aus/Nz map at the right, then click on the green button at the far right of "FNMOC Wave Watch 3 Sig Wave Heights [ft] ; Over Ocean Sfc Winds [kt] " It gives a 7 day graphical rain forecast. If you move your cursor back and forth over the boxes below the graphic its easy to watch the changing patterns.
